Solar Flare Frenzy: Earth’s Brush with the Biggest Geomagnetic Storm in 20 Years

This episode of SpaceTime explores the recent surge in solar activity, including the largest solar flare of the year and the most intense geomagnetic storm in two decades. Massive Solar Flare and Its Implications

We delve into the details of a powerful X 2.7 class solar flare that erupted from a newly active sunspot region, AR14087. Although the flare was not initially directed towards Earth, its rotation has now positioned it directly in our path. We discuss the mechanics of solar flares, their classification, and the potential impacts of such events on our planet, including disruptions to communication systems, satellite operations, and even power grids. The Gannon Storm: A Historic Geomagnetic Event

The episode highlights the Gannon Storm, a severe geomagnetic storm that struck Earth on May 10, 2024. Coinciding with a space weather exercise, this event caused significant disruptions, including high voltage power line failures and rerouted flights due to radiation exposure. We analyze its effects on the atmosphere, satellites, and even the ionosphere, revealing insights into how such storms can impact modern technology. Ancient Solar Storms and Their Modern Implications

In a fascinating segment, we discuss a groundbreaking study that identifies the strongest solar storm ever recorded, dating back to 12350 BCE. This ancient event, significantly more intense than any modern storm, provides invaluable data for understanding solar activity and its potential risks to contemporary infrastructure. Science Robert: Long Work Hours and Brain Changes

We also touch on a new study revealing how long working hours could alter brain structures, potentially affecting memory and emotional regulation.Join us as we unpack these cosmic phenomena and their implications for life on Earth and beyond.

This is Spaceime Series 28 episode 61


00:00:03.439 --> 00:00:06.110
for broadcast on the 21st of May


00:00:06.120 --> 00:00:09.589
2025. Coming up on Spaceime, the biggest


00:00:09.599 --> 00:00:11.910
solar flare this year, the biggest


00:00:11.920 --> 00:00:14.789
geomagnetic storm in the past 20 years,


00:00:14.799 --> 00:00:17.189
and the most extreme solar storm known


00:00:17.199 --> 00:00:19.750
to have hit the Earth. All that and more


00:00:19.760 --> 00:00:23.269
coming up on Spaceime.


00:00:23.279 --> 00:00:27.310
Welcome to Spaceime with Stuart Garry.


00:00:27.320 --> 00:00:34.180
[Music]




00:00:42.559 --> 00:00:44.310
Well, we've just experienced the largest


00:00:44.320 --> 00:00:46.389
solar flare so far this year, producing


00:00:46.399 --> 00:00:49.910
an X2.7 class event. The massive


00:00:49.920 --> 00:00:51.910
eruption emanated from a newly appeared


00:00:51.920 --> 00:00:53.830
active sunspot region cataloged as


00:00:53.840 --> 00:00:56.310
AR14087.


00:00:56.320 --> 00:00:58.229
It's one of two X-class flares and


00:00:58.239 --> 00:01:00.310
several smaller M-class events all


00:01:00.320 --> 00:01:02.549
coming from the same region. Now,


00:01:02.559 --> 00:01:04.469
luckily, they weren't pointed directly


00:01:04.479 --> 00:01:06.550
towards the Earth, leaving the planet on


00:01:06.560 --> 00:01:08.789
the outer edge of the strike zone. But,


00:01:08.799 --> 00:01:10.710
of course, that's now changed as this


00:01:10.720 --> 00:01:12.789
active region has now rotated to


00:01:12.799 --> 00:01:15.350
directly face the Earth. The event


00:01:15.360 --> 00:01:17.429
happened as the sun reaches solar


00:01:17.439 --> 00:01:20.149
maximum, the climax of its 11-year solar


00:01:20.159 --> 00:01:22.950
cycle. Solar flares are powerful blasts


00:01:22.960 --> 00:01:25.350
of energy erupting from sunspots on the


00:01:25.360 --> 00:01:28.149
sun's surface. Sunspots are slightly


00:01:28.159 --> 00:01:30.070
cooler regions on the sun's surface, the


00:01:30.080 --> 00:01:31.990
photosphere caused by magnetic field


00:01:32.000 --> 00:01:34.390
lines from deep inside the sun, breaking


00:01:34.400 --> 00:01:36.510
through the surface and looping out into


00:01:36.520 --> 00:01:39.190
space. Now, because the sun is fluid


00:01:39.200 --> 00:01:41.510
rather than solid, different latitudes


00:01:41.520 --> 00:01:43.429
rotate at different rates, and this


00:01:43.439 --> 00:01:45.590
causes the magnetic field lines to twist


00:01:45.600 --> 00:01:48.550
and snap. When they reconnect, a process


00:01:48.560 --> 00:01:50.069
called magnetic reconnection, it


00:01:50.079 --> 00:01:51.910
triggers pathful explosions near the


00:01:51.920 --> 00:01:54.710
surface known as solar flares. Solar


00:01:54.720 --> 00:01:56.630
flares are classified according to their


00:01:56.640 --> 00:01:59.350
strength. The smallest ones are B-class,


00:01:59.360 --> 00:02:01.749
that's followed by C, then M, and the


00:02:01.759 --> 00:02:04.550
largest AXclass flares. It's similar to


00:02:04.560 --> 00:02:06.550
the RTER scale used for earthquakes,


00:02:06.560 --> 00:02:08.550
with each letter representing a 10-fold


00:02:08.560 --> 00:02:11.350
logarithmic increase in energy output.


00:02:11.360 --> 00:02:13.910
So, an X-class flare is 10 times as


00:02:13.920 --> 00:02:16.150
strong as an M-class flare and 100 times


00:02:16.160 --> 00:02:18.630
as strong as a C-class flare. Within


00:02:18.640 --> 00:02:20.790
each letter class, there's a finer scale


00:02:20.800 --> 00:02:24.070
from 1 to 9. C-class flares are too weak


00:02:24.080 --> 00:02:26.070
to noticeably affect the Earth. But


00:02:26.080 --> 00:02:28.470
M-class flares can cause brief radio


00:02:28.480 --> 00:02:30.229
blackouts at the poles and minor


00:02:30.239 --> 00:02:32.470
radiation storms that could endanger


00:02:32.480 --> 00:02:35.430
people in space. Although X is the last


00:02:35.440 --> 00:02:37.110
letter, these flares can have more than


00:02:37.120 --> 00:02:39.830
10 times the power of an X1 class, so


00:02:39.840 --> 00:02:43.110
they can go much higher than an X9. The


00:02:43.120 --> 00:02:45.030
most powerful flare on record was back


00:02:45.040 --> 00:02:48.229
in 2003 during the last solar maximum.


00:02:48.239 --> 00:02:49.750
In fact, it was so powerful it


00:02:49.760 --> 00:02:51.670
overloaded the sensors measuring it.


00:02:51.680 --> 00:02:54.309
They cut out at X17, and the flare was


00:02:54.319 --> 00:02:57.509
later estimated to be about an X45.


00:02:57.519 --> 00:02:59.670
A powerful X-class flare like that can


00:02:59.680 --> 00:03:01.830
create long lasting radiation storms


00:03:01.840 --> 00:03:03.350
which can harm and even destroy


00:03:03.360 --> 00:03:05.350
satellites, give airline passengers


00:03:05.360 --> 00:03:07.750
flying near the poles dose of radiation


00:03:07.760 --> 00:03:09.750
scramble communication and navigation


00:03:09.760 --> 00:03:12.470
systems and even overload power grids


00:03:12.480 --> 00:03:14.309
causing widespread blackouts on the


00:03:14.319 --> 00:03:16.869
ground. The most powerful solar flares


00:03:16.879 --> 00:03:19.270
can trigger chronal mass ejections, huge


00:03:19.280 --> 00:03:21.509
blasts of the sun's material, including


00:03:21.519 --> 00:03:23.589
protons, electrons, magnetic field, and


00:03:23.599 --> 00:03:26.470
helium nuclei. Now, our current solar


00:03:26.480 --> 00:03:29.270
cycle number 25 began back in December


00:03:29.280 --> 00:03:32.149
2019 and so should be reaching solar max


00:03:32.159 --> 00:03:35.110
around now. This is when the sun reaches


00:03:35.120 --> 00:03:37.350
its most violent phase with lots of


00:03:37.360 --> 00:03:39.670
sunspot activity and consequently lots


00:03:39.680 --> 00:03:41.550
of solar flares and coronal mass


00:03:41.560 --> 00:03:43.910
ejections. A number of sunspots are


00:03:43.920 --> 00:03:46.149
predicted to reach a peak of around 115


00:03:46.159 --> 00:03:48.550
by July this year, making the current


00:03:48.560 --> 00:03:50.869
solar cycle weaker than average and only


00:03:50.879 --> 00:03:52.470
slightly more active than the previous


00:03:52.480 --> 00:03:54.789
solar cycle 24.


00:03:54.799 --> 00:03:56.470
During each of these roughly 11 year


00:03:56.480 --> 00:03:58.789
solar cycles, the sun's magnetic field


00:03:58.799 --> 00:04:01.030
flips in polarity. North pole becomes


00:04:01.040 --> 00:04:03.350
south and south pole north. And this


00:04:03.360 --> 00:04:05.830
flip occurs when the solar cycle reaches


00:04:05.840 --> 00:04:07.830
solar minimum with the next flip


00:04:07.840 --> 00:04:09.789
probably occurring around


00:04:09.799 --> 00:04:13.830
2030. This is spacetime. Still to come,


00:04:13.840 --> 00:04:15.830
the biggest geomagnetic storm in 20


00:04:15.840 --> 00:04:18.229
years and the most extreme solar storm


00:04:18.239 --> 00:04:20.310
ever known to have hit the earth. All


00:04:20.320 --> 00:04:24.920
that and more still to come on


00:04:24.930 --> 00:04:38.030
[Music]


00:04:38.040 --> 00:04:40.710
Spaceime. While spectacular, the most


00:04:40.720 --> 00:04:42.629
recent geomagnetic storm events we've


00:04:42.639 --> 00:04:44.710
seen pale into insignificance when


00:04:44.720 --> 00:04:46.390
compared to the solar storm that hit the


00:04:46.400 --> 00:04:48.310
Earth just a year ago, which has now


00:04:48.320 --> 00:04:50.390
officially been listed as the biggest in


00:04:50.400 --> 00:04:51.390
20


00:04:51.400 --> 00:04:54.629
years. Amazingly, that event coincided


00:04:54.639 --> 00:04:56.390
with the inaugural space weather


00:04:56.400 --> 00:04:59.030
tabletop exercise. The exercise was


00:04:59.040 --> 00:05:00.469
meant to be a training event where


00:05:00.479 --> 00:05:02.310
experts could work through realtime


00:05:02.320 --> 00:05:04.550
ramifications of a major geomagnetic


00:05:04.560 --> 00:05:06.550
storm, a global disruption to Earth's


00:05:06.560 --> 00:05:08.790
magnetic field. Now, as we mentioned


00:05:08.800 --> 00:05:10.950
earlier, geomagnetic storms can decimate


00:05:10.960 --> 00:05:12.950
satellites, overload electrical power


00:05:12.960 --> 00:05:14.870
grids, and expose astronauts to


00:05:14.880 --> 00:05:17.189
dangerous levels of radiation. So,


00:05:17.199 --> 00:05:19.510
minimizing the impact of such storms


00:05:19.520 --> 00:05:21.830
requires close coordination. And so,


00:05:21.840 --> 00:05:23.590
this meeting was a chance for scientists


00:05:23.600 --> 00:05:26.950
to practice. But then their simulation


00:05:26.960 --> 00:05:29.110
turned into reality. The director of


00:05:29.120 --> 00:05:30.950
NASA's space weather program, Jamie


00:05:30.960 --> 00:05:32.870
Favorvers, says the plan was to run


00:05:32.880 --> 00:05:35.189
through a hypothetical scenario, finding


00:05:35.199 --> 00:05:37.029
where existing processes worked and


00:05:37.039 --> 00:05:39.189
where they needed improving. But then


00:05:39.199 --> 00:05:40.710
this hypothetical scenario was


00:05:40.720 --> 00:05:43.830
interrupted by the real thing. On May


00:05:43.840 --> 00:05:47.350
the 10th, 2024, the first G5 or severe


00:05:47.360 --> 00:05:48.950
geomagnetic storm in more than two


00:05:48.960 --> 00:05:51.670
decades hit planet Earth. The event


00:05:51.680 --> 00:05:53.749
named the Ganon storm in memory of the


00:05:53.759 --> 00:05:55.590
leading space weather physicist Jennifer


00:05:55.600 --> 00:05:57.670
Ganon didn't cause any catastrophic


00:05:57.680 --> 00:06:00.469
damages. But a year on key insights into


00:06:00.479 --> 00:06:02.469
the Ganon storm are helping scientists


00:06:02.479 --> 00:06:03.990
understand and prepare for future


00:06:04.000 --> 00:06:06.870
geomagnetic events. The Ganon storm had


00:06:06.880 --> 00:06:09.510
effects both on and off our planet. On


00:06:09.520 --> 00:06:11.189
the ground, some high voltage power


00:06:11.199 --> 00:06:13.590
lines tripped, transformers overheated,


00:06:13.600 --> 00:06:15.990
and GPS guided tractors veered off


00:06:16.000 --> 00:06:17.909
course in the Midwest United States,


00:06:17.919 --> 00:06:19.990
further disrupting spring planting that


00:06:20.000 --> 00:06:22.390
had already been delayed by heavy rains.


00:06:22.400 --> 00:06:24.390
In the air, the threat of high radiation


00:06:24.400 --> 00:06:26.550
exposure as well as communications and


00:06:26.560 --> 00:06:28.390
navigation losses forced numerous


00:06:28.400 --> 00:06:30.469
transatlantic and trans-pacific flights


00:06:30.479 --> 00:06:32.870
to change course. During the storm,


00:06:32.880 --> 00:06:34.870
Earth's upper atmospheric layer, the


00:06:34.880 --> 00:06:37.070
thermosphere, heated to unusually high


00:06:37.080 --> 00:06:39.830
temperatures. In fact, at 60 km in


00:06:39.840 --> 00:06:41.189
altitude. The temperature, which


00:06:41.199 --> 00:06:44.150
typically peaks at around 650° C,


00:06:44.160 --> 00:06:46.749
surpassed over


00:06:46.759 --> 00:06:49.830
1,150°. NASA's global scale observations


00:06:49.840 --> 00:06:51.830
of the Lemon Disc or Gold Mission


00:06:51.840 --> 00:06:53.749
observed the atmosphere expanding from


00:06:53.759 --> 00:06:55.990
the heat generated to create a strong


00:06:56.000 --> 00:06:57.670
wind that lofted heavy nitrogen


00:06:57.680 --> 00:07:00.469
particles much higher into space. Now,


00:07:00.479 --> 00:07:02.309
in orbit, the expanded atmosphere


00:07:02.319 --> 00:07:04.070
increased drag on thousands of


00:07:04.080 --> 00:07:07.589
satellites. NASA's ISAT 2 lost altitude


00:07:07.599 --> 00:07:09.670
and wound up entering safe mode, while


00:07:09.680 --> 00:07:11.830
NASA's Colorado inner radiationbuilt


00:07:11.840 --> 00:07:14.670
experiment Cubat was forced to de-orbit


00:07:14.680 --> 00:07:16.870
prematurely. Other spacecraft such as


00:07:16.880 --> 00:07:18.790
the European Space Agency Sentinel


00:07:18.800 --> 00:07:20.790
mission required more power to maintain


00:07:20.800 --> 00:07:22.469
their orbital altitude, and they were


00:07:22.479 --> 00:07:23.990
forced to perform maneuvers to avoid


00:07:24.000 --> 00:07:26.469
collisions with space debris. The storm


00:07:26.479 --> 00:07:28.230
also dramatically changed the structure


00:07:28.240 --> 00:07:30.790
of the Earth's ionosphere. A dense zone


00:07:30.800 --> 00:07:32.469
of the ionosphere that normally covers


00:07:32.479 --> 00:07:34.390
the equator at night dipped downwards


00:07:34.400 --> 00:07:36.629
towards the south pole, forming a sort


00:07:36.639 --> 00:07:38.390
of check mark shape and causing a


00:07:38.400 --> 00:07:40.629
temporary gap near the equator. The


00:07:40.639 --> 00:07:42.430
Ganon storm also rocked Earth's


00:07:42.440 --> 00:07:44.390
magnetosphere, magnetic bubble that


00:07:44.400 --> 00:07:46.790
surrounds the planet. Data from NASA


00:07:46.800 --> 00:07:49.510
missions MMS and thermos Artemus saw


00:07:49.520 --> 00:07:51.510
giant curling waves of particles and


00:07:51.520 --> 00:07:53.749
rolled up magnetic fields along the edge


00:07:53.759 --> 00:07:56.150
of the coronal mass ejections. And these


00:07:56.160 --> 00:07:57.830
waves were perfectly sized to


00:07:57.840 --> 00:07:59.909
periodically dump extra magnetic energy


00:07:59.919 --> 00:08:01.909
and mass into the magnetosphere upon


00:08:01.919 --> 00:08:03.830
impact. In the process, creating the


00:08:03.840 --> 00:08:05.350
largest electrical current seen in the


00:08:05.360 --> 00:08:08.150
magnetosphere in 20 years. Incoming


00:08:08.160 --> 00:08:10.230
energy and particles from the sun also


00:08:10.240 --> 00:08:12.150
created two new temporary belts of


00:08:12.160 --> 00:08:13.869
energetic particles within the


00:08:13.879 --> 00:08:15.909
magnetosphere. These belts formed


00:08:15.919 --> 00:08:17.990
between the existing Van Allen radiation


00:08:18.000 --> 00:08:19.670
belts which permanently surround the


00:08:19.680 --> 00:08:22.230
Earth. The storm also ignited auroral


00:08:22.240 --> 00:08:24.150
activity around the globe, including at


00:08:24.160 --> 00:08:25.830
lower latitudes, where these celestial


00:08:25.840 --> 00:08:27.830
light shows are rare. NASA's


00:08:27.840 --> 00:08:29.830
aurorasaurus project was flooded with


00:08:29.840 --> 00:08:31.990
more than 6,000 observer reports from


00:08:32.000 --> 00:08:34.430
over 55 countries on all seven


00:08:34.440 --> 00:08:36.389
continents. Photographers helped


00:08:36.399 --> 00:08:38.070
scientists better understand why the


00:08:38.080 --> 00:08:40.310
aurora observed throughout Japan were


00:08:40.320 --> 00:08:42.550
magenta rather than the typical read in


00:08:42.560 --> 00:08:44.790
color. Researchers studied hundreds of


00:08:44.800 --> 00:08:46.870
photos and found that the auroray was


00:08:46.880 --> 00:08:49.590
surprisingly high, around 1,000 km above


00:08:49.600 --> 00:08:52.389
the ground. That's around 320 km higher


00:08:52.399 --> 00:08:55.190
than red auroray typically appear. In a


00:08:55.200 --> 00:08:56.389
paper published in the journal


00:08:56.399 --> 00:08:58.310
Scientific Reports, the authors found


00:08:58.320 --> 00:09:00.710
the peculiar color of the auroray likely


00:09:00.720 --> 00:09:02.550
resulted from a mix of red and blue


00:09:02.560 --> 00:09:04.870
aurora produced by oxygen and nitrogen


00:09:04.880 --> 00:09:06.710
molecules lofted higher than usual as


00:09:06.720 --> 00:09:09.030
the Ganon storm heated and expanded the


00:09:09.040 --> 00:09:11.430
upper atmosphere. And impacts of the


00:09:11.440 --> 00:09:13.590
sun's amped up solar activity didn't end


00:09:13.600 --> 00:09:16.230
in Earth's space. The solar region that


00:09:16.240 --> 00:09:18.070
sparked the Gaton storm eventually


00:09:18.080 --> 00:09:19.829
rotated away from our planet and


00:09:19.839 --> 00:09:21.670
redirected its outburst towards the


00:09:21.680 --> 00:09:24.470
planet Mars. As energetic particles from


00:09:24.480 --> 00:09:26.389
the sun struck the Martian atmosphere,


00:09:26.399 --> 00:09:28.630
NASA's Maven Orbiter watched the aurora


00:09:28.640 --> 00:09:30.870
engulf the red planet from May the 14th


00:09:30.880 --> 00:09:33.509
through to the 20th and solar particles


00:09:33.519 --> 00:09:35.509
overwhelmed the star camera on NASA's


00:09:35.519 --> 00:09:37.590
Mars Odyssey orbiter, causing the camera


00:09:37.600 --> 00:09:39.670
to cut out for almost an hour.


00:09:39.680 --> 00:09:41.590
Meanwhile, down on the Martian surface,


00:09:41.600 --> 00:09:43.350
images from the navigation cameras on


00:09:43.360 --> 00:09:45.430
NASA's Curiosity rover were freckled


00:09:45.440 --> 00:09:47.829
with snow, streaks, and specks caused by


00:09:47.839 --> 00:09:50.150
the charged particles. Curiosity's


00:09:50.160 --> 00:09:52.070
radiation assessment detector recorded


00:09:52.080 --> 00:09:53.990
the biggest surge of radiation since the


00:09:54.000 --> 00:09:56.310
rover landed on the red planet Mars Gale


00:09:56.320 --> 00:09:59.670
Crater back in 2012. Now, had astronauts


00:09:59.680 --> 00:10:01.110
been there, they would have received a


00:10:01.120 --> 00:10:04.150
radiation dose of around 8,100 micro


00:10:04.160 --> 00:10:06.310
grays. That's equivalent to some 30


00:10:06.320 --> 00:10:09.269
chest X-rays. The Ganon storm spread


00:10:09.279 --> 00:10:11.829
Aurora to unusually low latitudes. In


00:10:11.839 --> 00:10:13.110
fact, it's been called the best


00:10:13.120 --> 00:10:15.670
documented geomagnetic storm in history.


00:10:15.680 --> 00:10:17.190
And the data captured during this


00:10:17.200 --> 00:10:18.949
historic event will continue to be


00:10:18.959 --> 00:10:21.110
analyzed for years to come, revealing


00:10:21.120 --> 00:10:22.630
new lessons about the nature of


00:10:22.640 --> 00:10:24.949
geomagnetic storms and how best to


00:10:24.959 --> 00:10:30.389
weather them. This report from NASA TV.


00:10:30.399 --> 00:10:34.310
In May 2024, a spectacular multicolored


00:10:34.320 --> 00:10:36.949
light show flooded the skies across the


00:10:36.959 --> 00:10:39.630
world. These displays are known as the


00:10:39.640 --> 00:10:42.069
auroras. They're usually seen near the


00:10:42.079 --> 00:10:44.630
polar regions, but that May, sky


00:10:44.640 --> 00:10:46.949
watchers spotted the glowing lights far


00:10:46.959 --> 00:10:48.110
from Earth's


00:10:48.120 --> 00:10:50.710
poles. People were witnessing the


00:10:50.720 --> 00:10:53.550
biggest geomagnetic storm in over 20


00:10:53.560 --> 00:10:56.710
years. This storm was so intense. It was


00:10:56.720 --> 00:10:58.949
the most intense in two decades. This


00:10:58.959 --> 00:11:00.710
was one of those large events that we've


00:11:00.720 --> 00:11:03.670
been talking about for years. It all


00:11:03.680 --> 00:11:05.670
began from this active region on the


00:11:05.680 --> 00:11:08.389
sun. Active regions are known for having


00:11:08.399 --> 00:11:10.949
intense magnetic fields and the more


00:11:10.959 --> 00:11:13.110
tangled those fields become, the more


00:11:13.120 --> 00:11:16.949
likely they are to erupt. We watched the


00:11:16.959 --> 00:11:19.750
active region evolve and we thought that


00:11:19.760 --> 00:11:21.430
this might be something to watch and


00:11:21.440 --> 00:11:24.230
might be something active. Eventually,


00:11:24.240 --> 00:11:26.470
the active region unleashed a chain of


00:11:26.480 --> 00:11:29.310
huge solar eruptions directly towards


00:11:29.320 --> 00:11:33.030
us. What made it so strong was the fact


00:11:33.040 --> 00:11:35.430
that there was so much energy put off by


00:11:35.440 --> 00:11:37.910
the sun. It was really great conditions


00:11:37.920 --> 00:11:40.949
for the perfect storm. On May 10th, the


00:11:40.959 --> 00:11:43.509
eruptions reached Earth, triggering a


00:11:43.519 --> 00:11:45.509
global disruption to Earth's magnetic


00:11:45.519 --> 00:11:49.430
field, known as a geomagnetic storm. It


00:11:49.440 --> 00:11:52.710
was rated a G5, the rarest and strongest


00:11:52.720 --> 00:11:55.670
type. The powerful storm pushed auroras


00:11:55.680 --> 00:11:58.550
to appear in unusual places like Arizona


00:11:58.560 --> 00:12:01.310
in the United States and Perth in


00:12:01.320 --> 00:12:04.150
Australia. That energy interacted with


00:12:04.160 --> 00:12:06.310
the Earth and created the aurora and


00:12:06.320 --> 00:12:08.710
caused all sorts of disturbances that we


00:12:08.720 --> 00:12:10.949
felt here on the ground. The storm


00:12:10.959 --> 00:12:13.509
caused some high voltage lines to trip


00:12:13.519 --> 00:12:15.750
and transformers to overheat.


00:12:15.760 --> 00:12:18.470
transatlantic flights rerouted due to


00:12:18.480 --> 00:12:21.190
risks of high radiation exposure and


00:12:21.200 --> 00:12:23.150
communication and navigation


00:12:23.160 --> 00:12:25.750
disruptions. Further up, NASA saw


00:12:25.760 --> 00:12:28.069
Earth's upper atmosphere get unusually


00:12:28.079 --> 00:12:31.350
hot. The temperature 100 m up in the


00:12:31.360 --> 00:12:33.870
thermosphere usually peaks at


00:12:33.880 --> 00:12:37.509
1,200° F, but during the storm, it


00:12:37.519 --> 00:12:38.590
reached


00:12:38.600 --> 00:12:42.069
2,100° F. The heating caused the


00:12:42.079 --> 00:12:45.069
atmosphere to expand which affected


00:12:45.079 --> 00:12:47.590
satellites. There were thousands of


00:12:47.600 --> 00:12:49.829
satellites that had to move their orbits


00:12:49.839 --> 00:12:52.550
because the storm was coming through.


00:12:52.560 --> 00:12:55.350
The storm also affected the space beyond


00:12:55.360 --> 00:12:57.990
Earth. It created two new temporary


00:12:58.000 --> 00:13:00.590
belts of energetic particles around our


00:13:00.600 --> 00:13:03.190
planet, adding to Earth's two permanent


00:13:03.200 --> 00:13:06.069
ones, which are known as the Van Allen


00:13:06.079 --> 00:13:08.710
radiation belts. The particles in these


00:13:08.720 --> 00:13:11.030
belts can harm orbiting satellites and


00:13:11.040 --> 00:13:13.750
astronauts heading for deep space. So


00:13:13.760 --> 00:13:16.949
NASA studies them closely. As the sun


00:13:16.959 --> 00:13:19.350
rotated, the active region eventually


00:13:19.360 --> 00:13:21.990
moved away from Earth and redirected its


00:13:22.000 --> 00:13:25.430
outbursts towards Mars. On Mars, NASA's


00:13:25.440 --> 00:13:27.990
Curiosity rover saw solar particles from


00:13:28.000 --> 00:13:31.030
the storm. The rover also recorded the


00:13:31.040 --> 00:13:33.269
biggest surge of radiation since it


00:13:33.279 --> 00:13:36.310
landed in 2012. If an astronaut had been


00:13:36.320 --> 00:13:38.310
on the Martian surface, they would have


00:13:38.320 --> 00:13:40.629
received a radiation dose equivalent to


00:13:40.639 --> 00:13:43.150
30 chess X-rays at


00:13:43.160 --> 00:13:45.829
once. With spacecraft throughout the


00:13:45.839 --> 00:13:48.150
solar system and modern cameras in so


00:13:48.160 --> 00:13:50.470
many people's pockets, the storm was the


00:13:50.480 --> 00:13:53.590
most well doumented in history. There's


00:13:53.600 --> 00:13:56.310
lots of data. We're able to actually use


00:13:56.320 --> 00:13:58.230
that data to understand things and


00:13:58.240 --> 00:14:00.069
predict more and more how this is going


00:14:00.079 --> 00:14:02.550
to affect our Earth. Although the storm


00:14:02.560 --> 00:14:05.030
passed within days, NASA will continue


00:14:05.040 --> 00:14:07.430
to learn from the observations for years


00:14:07.440 --> 00:14:09.910
to come, helping us better prepare for


00:14:09.920 --> 00:14:11.910
the next big storm. And in that report


00:14:11.920 --> 00:14:13.990
from NASA TV, we heard from NASA


00:14:14.000 --> 00:14:17.470
helopysicist Kelly Cor. This is


00:14:17.480 --> 00:14:19.910
spaceime. Still to come, the most


00:14:19.920 --> 00:14:21.990
extreme solar storm ever known to have


00:14:22.000 --> 00:14:23.829
hit the Earth. And later in the science


00:14:23.839 --> 00:14:26.069
report, a new study claims people who


00:14:26.079 --> 00:14:28.710
work long hours could have altered brain


00:14:28.720 --> 00:14:31.189
structures. All that and more still to


00:14:31.199 --> 00:14:35.100
come on


00:14:35.110 --> 00:14:41.940
[Music]




00:14:47.639 --> 00:14:50.069
Spaceime. New researchers uncovered the


00:14:50.079 --> 00:14:52.470
strongest solar event ever recorded in


00:14:52.480 --> 00:14:54.230
the process rewriting science's


00:14:54.240 --> 00:14:56.230
understanding of space weather and


00:14:56.240 --> 00:14:59.030
radiocarbon dating. This new finding


00:14:59.040 --> 00:15:00.949
expands the timeline and intensity of


00:15:00.959 --> 00:15:03.030
known solar activity and sets a new


00:15:03.040 --> 00:15:05.069
upper boundary for such solar


00:15:05.079 --> 00:15:07.189
phenomenon. The study's authors


00:15:07.199 --> 00:15:09.030
discovered an extreme spike in


00:15:09.040 --> 00:15:11.870
radiocarbon corresponding to the


00:15:11.880 --> 00:15:15.110
12,350 BCE during the dusk of the last


00:15:15.120 --> 00:15:18.389
ice age. The study by Celia Gulabeko and


00:15:18.399 --> 00:15:20.629
Ilia Uzoskin from the University of Ulo


00:15:20.639 --> 00:15:22.470
in Finland utilized their newly


00:15:22.480 --> 00:15:24.230
developed chemistry climate model which


00:15:24.240 --> 00:15:25.990
was specifically designed to reconstruct


00:15:26.000 --> 00:15:27.990
solar particle storms under ancient


00:15:28.000 --> 00:15:30.629
global climatic conditions. The model


00:15:30.639 --> 00:15:32.629
confirmed that the detected solar event


00:15:32.639 --> 00:15:35.269
was approximately 18% stronger than the


00:15:35.279 --> 00:15:38.389
notorious year 775 event which until now


00:15:38.399 --> 00:15:40.470
had been the strongest solar storm ever


00:15:40.480 --> 00:15:43.670
recorded using tree ring archives. Leeno


00:15:43.680 --> 00:15:45.430
says that compared to the largest event


00:15:45.440 --> 00:15:47.030
in the modern satellite era, which is


00:15:47.040 --> 00:15:50.110
the 2005 particle storm, the ancient


00:15:50.120 --> 00:15:53.430
12,350 B.CE event was more than 500


00:15:53.440 --> 00:15:56.150
times more intense. Other large known


00:15:56.160 --> 00:15:57.990
solar particle events occurred around


00:15:58.000 --> 00:16:04.030
the years 994, 663 B.CE, 5259 B.CE, and


00:16:04.040 --> 00:16:07.030
7176 B.CE. And a few other candidates


00:16:07.040 --> 00:16:09.350
are still being investigated. The new


00:16:09.360 --> 00:16:11.350
model was verified using wood samples


00:16:11.360 --> 00:16:13.509
recently found in the French Alps dating


00:16:13.519 --> 00:16:17.430
back some 4,300 years. Solar particle


00:16:17.440 --> 00:16:19.590
storms are rare, but when they occur,


00:16:19.600 --> 00:16:21.829
they bombard the earth with an enormous


00:16:21.839 --> 00:16:24.389
amount of high energy particles. In


00:16:24.399 --> 00:16:26.550
comparison, the famous Carrington solar


00:16:26.560 --> 00:16:29.509
storm of 1859 was a different kind of


00:16:29.519 --> 00:16:31.590
event and not accompanied by a solar


00:16:31.600 --> 00:16:33.749
particle storm. Gulabeno says the


00:16:33.759 --> 00:16:37.110
ancient event in 12,350 B.CE CE is the


00:16:37.120 --> 00:16:39.189
only known extreme solar particle event


00:16:39.199 --> 00:16:41.509
outside the holene epoch which is the


00:16:41.519 --> 00:16:43.790
past 12,000 years of stable warm


00:16:43.800 --> 00:16:46.150
climate. With this model, the authors


00:16:46.160 --> 00:16:47.670
were able to assess the strength,


00:16:47.680 --> 00:16:49.590
timing, and terrestrial effects of what


00:16:49.600 --> 00:16:51.350
is now the most powerful and extreme


00:16:51.360 --> 00:16:54.230
solar particle event ever known. Solar


00:16:54.240 --> 00:16:56.230
particle storms can greatly enhance the


00:16:56.240 --> 00:16:58.550
normal production of cosmogenic isotopes


00:16:58.560 --> 00:17:00.629
like radiocarbon 14 in the atmosphere,


00:17:00.639 --> 00:17:02.470
which are produced by galactic cosmic


00:17:02.480 --> 00:17:05.510
rays. Such enhanced production preserved


00:17:05.520 --> 00:17:07.909
in annual tree rings serves as a clear


00:17:07.919 --> 00:17:10.230
cosmic timestamp, making possible


00:17:10.240 --> 00:17:13.350
absolute dating of tree samples. These


00:17:13.360 --> 00:17:15.590
dramatic spikes, known as Miyaki events


00:17:15.600 --> 00:17:17.270
after the Japanese researcher first


00:17:17.280 --> 00:17:19.270
discovered them, offer invaluable data


00:17:19.280 --> 00:17:21.029
for scientists studying both solar


00:17:21.039 --> 00:17:23.029
activity, ancient Earth systems, and


00:17:23.039 --> 00:17:25.829
space climate. Miyaki events allow


00:17:25.839 --> 00:17:27.990
scientists to pin out exact calendar


00:17:28.000 --> 00:17:29.669
years in floating archaeological


00:17:29.679 --> 00:17:32.549
chronologies. Radiocarbon signals from


00:17:32.559 --> 00:17:34.230
such events have already enabled


00:17:34.240 --> 00:17:36.310
researchers to precisely date Viking


00:17:36.320 --> 00:17:37.669
settlements in New Foundland and


00:17:37.679 --> 00:17:40.150
Neolithic communities in Greece. The


00:17:40.160 --> 00:17:41.909
findings are revising science's


00:17:41.919 --> 00:17:44.230
understanding of solar physics and space


00:17:44.240 --> 00:17:46.310
weather extremes. And this event


00:17:46.320 --> 00:17:49.190
establishes a new worst case scenario.


00:17:49.200 --> 00:17:51.350
Understanding its scale is critical for


00:17:51.360 --> 00:17:53.270
evaluating the risks posed by future


00:17:53.280 --> 00:17:55.270
solar storms to modern infrastructure


00:17:55.280 --> 00:17:57.350
such as satellites, power grids, and


00:17:57.360 --> 00:18:00.230
communication and navigation systems.


00:18:00.240 --> 00:18:01.600
This is space


00:18:01.610 --> 00:18:16.750
[Music]


00:18:16.760 --> 00:18:19.110
time. And time out of tech. Another


00:18:19.120 --> 00:18:20.470
brief look at some of the other stories


00:18:20.480 --> 00:18:22.390
making news in science this week with a


00:18:22.400 --> 00:18:25.190
science report. A new study claims that


00:18:25.200 --> 00:18:27.270
people who work long hours could have


00:18:27.280 --> 00:18:29.909
altered brain structures. A report in


00:18:29.919 --> 00:18:31.110
the Journal of Occupational


00:18:31.120 --> 00:18:32.950
Environmental Medicine looked at brain


00:18:32.960 --> 00:18:35.190
scans of 110 participants who worked


00:18:35.200 --> 00:18:37.830
either 52 or more hours a week or a


00:18:37.840 --> 00:18:40.950
standard 35 to 40hour week. They found


00:18:40.960 --> 00:18:42.710
that when compared with those who work


00:18:42.720 --> 00:18:44.310
standard hours, those who worked


00:18:44.320 --> 00:18:46.470
excessive hours had changes in brain


00:18:46.480 --> 00:18:48.710
regions associated with working memory,


00:18:48.720 --> 00:18:50.470
problem solving, and emotional


00:18:50.480 --> 00:18:52.870
regulation. Now, while this study only


00:18:52.880 --> 00:18:54.950
provides a snapshot, can't be used to


00:18:54.960 --> 00:18:56.630
show cause and effect, authors say


00:18:56.640 --> 00:18:58.470
previous research had linked overwork


00:18:58.480 --> 00:19:00.230
with various health issues, and these


00:19:00.240 --> 00:19:02.070
results can help provide more insights


00:19:02.080 --> 00:19:04.909
into overwork and our


00:19:04.919 --> 00:19:07.830
bodies. Engineers have invented a smart


00:19:07.840 --> 00:19:09.990
sponge-like device that can capture


00:19:10.000 --> 00:19:12.710
water from thin air. A report in the


00:19:12.720 --> 00:19:14.789
journal of cleaner production claims the


00:19:14.799 --> 00:19:16.950
system uses the sun's energy and works


00:19:16.960 --> 00:19:18.710
even in low humidity where other


00:19:18.720 --> 00:19:20.870
technologies such as fog harvesting and


00:19:20.880 --> 00:19:23.350
radiative cooling have struggled. They


00:19:23.360 --> 00:19:25.110
say the water from their device remained


00:19:25.120 --> 00:19:26.549
effective across a broad range of


00:19:26.559 --> 00:19:29.029
humidity levels from 30 to 90% and


00:19:29.039 --> 00:19:34.230
temperature levels between 5 and 55° C.


00:19:34.240 --> 00:19:36.549
A new study claims that a ban on


00:19:36.559 --> 00:19:38.870
smartphones and social media access for


00:19:38.880 --> 00:19:40.870
kids doesn't promote a healthy use of


00:19:40.880 --> 00:19:43.510
technology by children. The findings


00:19:43.520 --> 00:19:45.270
reported in the British Medical Journal


00:19:45.280 --> 00:19:46.870
claims the focus should move to a


00:19:46.880 --> 00:19:48.549
rightsbased approach with age


00:19:48.559 --> 00:19:50.549
appropriate design and education, one


00:19:50.559 --> 00:19:52.150
that protects kids from harm while


00:19:52.160 --> 00:19:53.990
developing the right skills to help them


00:19:54.000 --> 00:19:56.630
participate in a digital society. The


00:19:56.640 --> 00:19:58.549
authors say that blanket restrictions on


00:19:58.559 --> 00:20:00.870
technology like smartphones are a stop


00:20:00.880 --> 00:20:02.950
gap solution that does little to support


00:20:02.960 --> 00:20:05.110
a child's longerterm healthy engagement


00:20:05.120 --> 00:20:08.070
with digital spaces across school, home,


00:20:08.080 --> 00:20:10.190
and other


00:20:10.200 --> 00:20:12.549
occasions. Australian telecommunications


00:20:12.559 --> 00:20:14.630
giant Telstra has begun testing the


00:20:14.640 --> 00:20:16.870
Starlink broadband satellite network for


00:20:16.880 --> 00:20:18.789
remote customers beyond the conventional


00:20:18.799 --> 00:20:21.270
cell phone network. With the details,


00:20:21.280 --> 00:20:23.029
we're joined by technology editor Alex


00:20:23.039 --> 00:20:26.070
Sahara from techadvice.life. life. Yeah.


00:20:26.080 --> 00:20:27.350
Well, they've been testing their


00:20:27.360 --> 00:20:29.990
Starlink capability to send text


00:20:30.000 --> 00:20:31.750
messages to people and they're going to


00:20:31.760 --> 00:20:33.830
launch this in Australia later this


00:20:33.840 --> 00:20:35.830
year. Now, this mirrors what Verizon did


00:20:35.840 --> 00:20:38.310
in the US with their ability to send


00:20:38.320 --> 00:20:40.470
messages via Star Link. This is


00:20:40.480 --> 00:20:42.710
augmented over what Apple launched a


00:20:42.720 --> 00:20:44.870
couple of years ago or the iPhone 14


00:20:44.880 --> 00:20:46.149
which has now been extended to the


00:20:46.159 --> 00:20:48.630
iPhone 13 to send emergency messages via


00:20:48.640 --> 00:20:50.549
SOS and now of course you can send other


00:20:50.559 --> 00:20:52.870
messages and use find my let your


00:20:52.880 --> 00:20:54.149
relatives see where you are. But in


00:20:54.159 --> 00:20:55.350
other parts of the world like Australia


00:20:55.360 --> 00:20:57.029
and New Zealand and phone companies are


00:20:57.039 --> 00:20:59.029
like, "Wow, well, we can send messages


00:20:59.039 --> 00:21:01.270
and hopefully eventually soon also make


00:21:01.280 --> 00:21:03.270
phone calls via satellite networks from


00:21:03.280 --> 00:21:05.430
people are outside of the traditional


00:21:05.440 --> 00:21:07.510
cellular networks." And this is a very


00:21:07.520 --> 00:21:09.909
handy capability. So Telstra has sent


00:21:09.919 --> 00:21:12.470
55,000 text messages in its testing


00:21:12.480 --> 00:21:14.789
phase. And so this is basic testing. You


00:21:14.799 --> 00:21:16.549
don't have to be doing this for


00:21:16.559 --> 00:21:18.789
emergency purposes, but it is for hard


00:21:18.799 --> 00:21:20.710
to reach places where the network


00:21:20.720 --> 00:21:22.789
doesn't exist. You know, this is part of


00:21:22.799 --> 00:21:24.789
the ability for regional Australians


00:21:24.799 --> 00:21:26.070
primarily because they're the ones who


00:21:26.080 --> 00:21:28.549
live outside of the uh traditional 4G


00:21:28.559 --> 00:21:31.110
and 5G mobile network coverage. And they


00:21:31.120 --> 00:21:33.270
did also send 500 plus messages in the


00:21:33.280 --> 00:21:34.950
live trial and they've been also sending


00:21:34.960 --> 00:21:37.110
GPS coordinates and emerges via text


00:21:37.120 --> 00:21:39.750
message. So, this is an awesome update


00:21:39.760 --> 00:21:41.830
to the ability for the world to stay in


00:21:41.840 --> 00:21:44.390
contact wherever you are. and uh the new


00:21:44.400 --> 00:21:46.310
ubiquitous communications that we've


00:21:46.320 --> 00:21:48.070
sort of I guess dreamed of for for years


00:21:48.080 --> 00:21:50.470
ever since we've had satellite calls via


00:21:50.480 --> 00:21:52.710
Aridium and then uh the mobile networks


00:21:52.720 --> 00:21:53.990
that have grown and grown and this is


00:21:54.000 --> 00:21:55.909
the next logical step and given the fact


00:21:55.919 --> 00:21:58.149
that Elon Musk wants to get us all to


00:21:58.159 --> 00:22:00.310
Mars. No doubt at some point soon this


00:22:00.320 --> 00:22:01.990
will be interplanetary as well but for


00:22:02.000 --> 00:22:03.669
the time being we're still firmly


00:22:03.679 --> 00:22:05.270
anchored here on Earth. That's Alex
