00:00:00.359 --> 00:00:02.270
welcome to astronomy daily your source
00:00:02.280 --> 00:00:04.749
for the latest space and astronomy news
00:00:04.759 --> 00:00:06.670
I'm Anna and today we're covering some
00:00:06.680 --> 00:00:08.270
fascinating stories from across the
00:00:08.280 --> 00:00:10.589
cosmos from groundbreaking research and
00:00:10.599 --> 00:00:13.509
alien life detection to massive Cosmic
00:00:13.519 --> 00:00:16.230
structures so let's get straight into
00:00:16.240 --> 00:00:18.750
it in an exciting development for the
00:00:18.760 --> 00:00:20.870
search for extraterrestrial life
00:00:20.880 --> 00:00:22.870
researchers in Germany have created a
00:00:22.880 --> 00:00:25.310
new and remarkably simple method that
00:00:25.320 --> 00:00:27.349
could revolutionize how we look for life
00:00:27.359 --> 00:00:30.070
on other planets the technique focuses
00:00:30.080 --> 00:00:32.630
on detecting movement in microorganisms
00:00:32.640 --> 00:00:34.229
specifically their attraction to certain
00:00:34.239 --> 00:00:37.430
chemicals a process known as chemotaxis
00:00:37.440 --> 00:00:39.389
the team tested their method on three
00:00:39.399 --> 00:00:41.950
different types of microbes two bacteria
00:00:41.960 --> 00:00:44.750
and one ARA using an amino acid called
00:00:44.760 --> 00:00:47.310
Els Serene as bait all three species
00:00:47.320 --> 00:00:48.990
showed clear movement toward the
00:00:49.000 --> 00:00:50.950
chemical which is particularly
00:00:50.960 --> 00:00:52.790
significant since these organisms were
00:00:52.800 --> 00:00:55.270
chosen for their ability to survive in
00:00:55.280 --> 00:00:57.270
extreme conditions similar to what we
00:00:57.280 --> 00:01:00.189
might find on Mars what makes this
00:01:00.199 --> 00:01:02.709
Discovery particularly promising is its
00:01:02.719 --> 00:01:05.350
Simplicity instead of requiring complex
00:01:05.360 --> 00:01:08.109
equipment the method uses a basic slide
00:01:08.119 --> 00:01:10.149
with two Chambers separated by a thin
00:01:10.159 --> 00:01:12.990
membrane microbes are placed on one side
00:01:13.000 --> 00:01:15.310
and Els Serene on the other if living
00:01:15.320 --> 00:01:17.030
organisms are present and capable of
00:01:17.040 --> 00:01:18.870
movement they'll naturally swim through
00:01:18.880 --> 00:01:20.910
the membrane toward the chemical the
00:01:20.920 --> 00:01:22.710
implications for future space missions
00:01:22.720 --> 00:01:25.030
are significant Els Serene is believed
00:01:25.040 --> 00:01:27.469
to exist on Mars and if Martian life
00:01:27.479 --> 00:01:29.550
shares any biochemical similarities with
00:01:29.560 --> 00:01:31.990
Earth life this method could provide a
00:01:32.000 --> 00:01:34.590
straightforward way to detect it while
00:01:34.600 --> 00:01:36.429
some modifications would be needed to
00:01:36.439 --> 00:01:38.149
make the system spaceworthy and
00:01:38.159 --> 00:01:40.590
automated the fundamental Simplicity of
00:01:40.600 --> 00:01:42.429
the approach makes it an attractive
00:01:42.439 --> 00:01:45.230
option for future missions this method
00:01:45.240 --> 00:01:46.670
could be particularly valuable for
00:01:46.680 --> 00:01:49.030
exploring places like Europa Jupiter's
00:01:49.040 --> 00:01:50.870
moon where we suspect there might be
00:01:50.880 --> 00:01:53.469
oceans that could Harbor Life by making
00:01:53.479 --> 00:01:55.990
life detection cheaper and faster future
00:01:56.000 --> 00:01:57.830
missions could achieve more with fewer
00:01:57.840 --> 00:02:00.230
resources potentially accelerating our
00:02:00.240 --> 00:02:01.910
search for life beyond
00:02:01.920 --> 00:02:04.830
Earth let's get a Mars update now a
00:02:04.840 --> 00:02:06.550
fascinating Discovery has emerged from
00:02:06.560 --> 00:02:08.630
Mars where scientists have uncovered
00:02:08.640 --> 00:02:11.029
what they're calling a seismic Highway
00:02:11.039 --> 00:02:13.589
deep within the red planet this finding
00:02:13.599 --> 00:02:15.630
comes from analyzing data from NASA's
00:02:15.640 --> 00:02:17.630
Insight Lander which has completely
00:02:17.640 --> 00:02:19.550
changed our understanding of how seismic
00:02:19.560 --> 00:02:21.790
waves travel through Mars by comparing
00:02:21.800 --> 00:02:24.190
Mars Quake data with impact craters
00:02:24.200 --> 00:02:25.790
identified by the Mars reconnaissance
00:02:25.800 --> 00:02:28.110
Orbiter researchers found something
00:02:28.120 --> 00:02:30.990
unexpected when meteoroids strike Mars
00:02:31.000 --> 00:02:33.150
they create seismic waves that travel
00:02:33.160 --> 00:02:34.589
much deeper into the planet than
00:02:34.599 --> 00:02:36.710
previously thought rather than being
00:02:36.720 --> 00:02:39.149
dampened by the crust as expected these
00:02:39.159 --> 00:02:41.190
waves appear to find a more direct route
00:02:41.200 --> 00:02:43.550
through the planet's mantle one
00:02:43.560 --> 00:02:45.949
particular impact crater measuring 71 ft
00:02:45.959 --> 00:02:48.790
in diameter proved especially revealing
00:02:48.800 --> 00:02:50.470
the seismic signals from this impact
00:02:50.480 --> 00:02:52.830
were detected at the curus fossy region
00:02:52.840 --> 00:02:54.509
over a thousand miles away from the
00:02:54.519 --> 00:02:57.350
impact site this remarkable distance far
00:02:57.360 --> 00:02:58.750
exceeded what scientists thought
00:02:58.760 --> 00:03:01.270
possible based on their existing models
00:03:01.280 --> 00:03:04.030
of Mars's interior structure the
00:03:04.040 --> 00:03:05.710
discovery is forcing scientists to
00:03:05.720 --> 00:03:07.670
reassess their understanding of Mars's
00:03:07.680 --> 00:03:10.390
composition and internal structure as
00:03:10.400 --> 00:03:12.470
one researcher put it they used to think
00:03:12.480 --> 00:03:14.509
most seismic energy was confined to
00:03:14.519 --> 00:03:16.990
traveling within the Martian crust
00:03:17.000 --> 00:03:19.509
instead they found this deeper faster
00:03:19.519 --> 00:03:21.789
pathway through the mantle allowing
00:03:21.799 --> 00:03:23.789
seismic signals to reach much more
00:03:23.799 --> 00:03:26.309
distant regions of the planet this
00:03:26.319 --> 00:03:27.910
breakthrough was made possible through
00:03:27.920 --> 00:03:29.270
the clever use of artificial
00:03:29.280 --> 00:03:30.910
intelligence
00:03:30.920 --> 00:03:32.710
scientists developed a machine learning
00:03:32.720 --> 00:03:35.110
algorithm that could quickly analyze
00:03:35.120 --> 00:03:36.949
tens of thousands of images from the
00:03:36.959 --> 00:03:39.429
Mars reconnaissance Orbiter identifying
00:03:39.439 --> 00:03:41.710
impact craters in a matter of days
00:03:41.720 --> 00:03:43.030
rather than the years it would have
00:03:43.040 --> 00:03:45.949
taken to do manually what's particularly
00:03:45.959 --> 00:03:48.350
exciting about this discovery is how it
00:03:48.360 --> 00:03:50.710
might help us better understand not just
00:03:50.720 --> 00:03:54.069
Mars but other rocky planets as well by
00:03:54.079 --> 00:03:56.110
revealing these unexpected properties of
00:03:56.120 --> 00:03:58.789
Mars's interior we're gaining valuable
00:03:58.799 --> 00:04:00.830
insights into planet AR Evolution that
00:04:00.840 --> 00:04:03.429
could apply to Earth the moon and
00:04:03.439 --> 00:04:05.630
Beyond here's news of a party I wouldn't
00:04:05.640 --> 00:04:07.949
mind going to maybe my invitations in
00:04:07.959 --> 00:04:10.869
the mail but I won't hold my breathe the
00:04:10.879 --> 00:04:13.190
L observatory in Flagstaff Arizona is
00:04:13.200 --> 00:04:15.550
gearing up for an exciting celebration
00:04:15.560 --> 00:04:17.870
as it marks the 95th Anniversary of one

this year's Festival theme to boldly go
00:04:34.240 --> 00:04:36.629
beyond New Horizons carries special
00:04:36.639 --> 00:04:38.790
significance as it also marks the 10th
00:04:38.800 --> 00:04:40.950
anniversary of NASA's New Horizons
00:04:40.960 --> 00:04:43.270
Mission which gave us our first detailed
00:04:43.280 --> 00:04:45.629
glimpses of this fascinating dwarf
00:04:45.639 --> 00:04:48.150
planet the celebration promises an
00:04:48.160 --> 00:04:50.510

guest is Adam neoy son of Star Trek
00:05:02.000 --> 00:05:04.070
Legend Leonard neoy who brings an
00:05:04.080 --> 00:05:05.909
intriguing connection between science
00:05:05.919 --> 00:05:07.909
fiction and real world
00:05:07.919 --> 00:05:10.189
astronomy he'll be joining an impressive
00:05:10.199 --> 00:05:12.390
panel alongside New Horizon's principal
00:05:12.400 --> 00:05:14.629
investigator Alan Stern and renowned
00:05:14.639 --> 00:05:16.629
comet hunter David Levy at the Orum
00:05:16.639 --> 00:05:19.189
theater the connection between the nemoy
00:05:19.199 --> 00:05:21.749
family and the observatory runs deeper
00:05:21.759 --> 00:05:24.670
than you might expect Leonard nemoy who
00:05:24.680 --> 00:05:27.070
grew up in Boston's immigrant West End
00:05:27.080 --> 00:05:29.070
had a genuine fascination with astronomy
00:05:29.080 --> 00:05:31.749
and space exploration he owned his own
00:05:31.759 --> 00:05:34.029
telescope and even visited the LEL
00:05:34.039 --> 00:05:36.189
Observatory bringing home models of
00:05:36.199 --> 00:05:37.990
satellites from his visits to various
00:05:38.000 --> 00:05:40.830
space facilities the festival will also
00:05:40.840 --> 00:05:42.550
feature a special presentation where
00:05:42.560 --> 00:05:45.070
Adam neoy will discuss his book the most
00:05:45.080 --> 00:05:47.390
human exploring his relationship with
00:05:47.400 --> 00:05:49.590
his father followed by a screening of
00:05:49.600 --> 00:05:51.870
his documentary For the Love of
00:05:51.880 --> 00:05:54.029
Spock it's a fitting tribute that
00:05:54.039 --> 00:05:55.590
Bridges the gap between science
00:05:55.600 --> 00:05:57.870
Fiction's ability to inspire and the
00:05:57.880 --> 00:06:00.230
real world pursuit of astrona omal
00:06:00.240 --> 00:06:01.550
discovery that continues at L
00:06:01.560 --> 00:06:04.270
Observatory to this day in an
00:06:04.280 --> 00:06:05.909
extraordinary Discovery that's pushing
00:06:05.919 --> 00:06:07.909
the boundaries of our understanding
00:06:07.919 --> 00:06:09.629
astronomers have identified one of the
00:06:09.639 --> 00:06:12.550
largest exoplanets ever found orbiting a
00:06:12.560 --> 00:06:15.749
relatively small star about 244 light
00:06:15.759 --> 00:06:19.710
years from Earth named Gaia 4B this
00:06:19.720 --> 00:06:21.390
Mysterious World was discovered through
00:06:21.400 --> 00:06:24.749
the European space agency's Gaia Mission
00:06:24.759 --> 00:06:26.589
which detected the planet by observing
00:06:26.599 --> 00:06:28.950
how its massive gravitational pull
00:06:28.960 --> 00:06:30.629
affects its parent Stars movement
00:06:30.639 --> 00:06:33.270
through space this Celestial giant
00:06:33.280 --> 00:06:36.350
boasts a mass 11.8 times that of Jupiter
00:06:36.360 --> 00:06:38.670
making it a truly remarkable find
00:06:38.680 --> 00:06:40.270
especially considering it orbits a
00:06:40.280 --> 00:06:42.790
relatively modest orange dwarf star with
00:06:42.800 --> 00:06:46.070
just 64% of our Sun's mass while it
00:06:46.080 --> 00:06:47.790
follows an orbit similar in distance to
00:06:47.800 --> 00:06:50.270
Mars's path around our sun its cooler
00:06:50.280 --> 00:06:53.029
Star means temperatures on Gaia 4B are
00:06:53.039 --> 00:06:55.550
likely quite chil what makes this
00:06:55.560 --> 00:06:57.589
discovery particularly intriguing is how
00:06:57.599 --> 00:06:58.990
it challenges our traditional
00:06:59.000 --> 00:07:00.070
classification
00:07:00.080 --> 00:07:02.749
of cosmic objects the line between what
00:07:02.759 --> 00:07:04.909
we call a planet and what we consider a
00:07:04.919 --> 00:07:07.550
failed star or brown dwarf becomes
00:07:07.560 --> 00:07:10.830
remarkably blurry with Gaia 4B while its
00:07:10.840 --> 00:07:13.350
mass Falls below the typical 13 Jupiter
00:07:13.360 --> 00:07:15.270
Mass threshold used to define Brown
00:07:15.280 --> 00:07:17.670
dwarfs the way it likely formed raises
00:07:17.680 --> 00:07:19.469
fascinating questions about its true
00:07:19.479 --> 00:07:22.670
nature the Stars chemical composition
00:07:22.680 --> 00:07:24.110
suggests there might not have been
00:07:24.120 --> 00:07:25.790
enough heavy elements available during
00:07:25.800 --> 00:07:28.230
the system's formation to build such a
00:07:28.240 --> 00:07:29.670
massive Planet through through
00:07:29.680 --> 00:07:32.110
traditional planetary formation
00:07:32.120 --> 00:07:34.749
processes this hints at the possibility
00:07:34.759 --> 00:07:37.909
that Gia 4B may have formed more like a
00:07:37.919 --> 00:07:40.270
star through the gravitational collapse
00:07:40.280 --> 00:07:42.710
of a gas cloud rather than the way we
00:07:42.720 --> 00:07:45.749
think most planets come together whether
00:07:45.759 --> 00:07:47.950
we call it a supersized planet or a
00:07:47.960 --> 00:07:51.149
failed star Gia 4B represents one of the
00:07:51.159 --> 00:07:53.270
most massive worlds ever found around a
00:07:53.280 --> 00:07:56.149
lower mass star making it an invaluable
00:07:56.159 --> 00:07:57.790
Discovery for understanding how these
00:07:57.800 --> 00:07:59.990
extraordinary systems form
00:08:00.000 --> 00:08:02.550
evolve as we continue to analyze data
00:08:02.560 --> 00:08:04.830
from the Gaia Mission we may find more
00:08:04.840 --> 00:08:06.430
of these boundary pushing worlds that
00:08:06.440 --> 00:08:08.149
help us better understand the diverse
00:08:08.159 --> 00:08:10.510
range of objects populating our
00:08:10.520 --> 00:08:12.830
galaxy now try and get your brain around
00:08:12.840 --> 00:08:14.510
this just when we thought we had a
00:08:14.520 --> 00:08:17.110
handle on the scale of cosmic structures
00:08:17.120 --> 00:08:19.070
astronomers have made a mind-bending
00:08:19.080 --> 00:08:21.029
discovery that's forcing us to think
00:08:21.039 --> 00:08:23.510
even bigger they've Found What appears
00:08:23.520 --> 00:08:25.149
to be the largest structure ever
00:08:25.159 --> 00:08:26.950
observed in our universe and they've
00:08:26.960 --> 00:08:30.350
named it queo after an ancient incin
00:08:30.360 --> 00:08:32.829
measuring system to give you an idea of
00:08:32.839 --> 00:08:35.110
just how massive this structure is it
00:08:35.120 --> 00:08:38.029
contains roughly 200 quadrillion times
00:08:38.039 --> 00:08:40.430
the mass of our sun that's a number so
00:08:40.440 --> 00:08:43.029
large it's rarely used even in astronomy
00:08:43.039 --> 00:08:44.710
where we regularly deal with Cosmic
00:08:44.720 --> 00:08:47.030
scale measurements and if that wasn't
00:08:47.040 --> 00:08:49.310
impressive enough kipo stretches across
00:08:49.320 --> 00:08:52.670
1.3 billion light years of space this
00:08:52.680 --> 00:08:54.150
super structure isn't just breaking
00:08:54.160 --> 00:08:56.670
records it's reshaping our understanding
00:08:56.680 --> 00:09:00.310
of the cosmos kipu and four other newly
00:09:00.320 --> 00:09:01.670
discovered super structures together
00:09:01.680 --> 00:09:05.030
contain 45% of all Galaxy clusters in
00:09:05.040 --> 00:09:07.350
their region of space 30% of the
00:09:07.360 --> 00:09:11.269
galaxies and 25% of all matter they're
00:09:11.279 --> 00:09:13.870
essentially Cosmic metropolises on an
00:09:13.880 --> 00:09:16.790
unimaginable scale these structures are
00:09:16.800 --> 00:09:18.590
so massive that they actually distort
00:09:18.600 --> 00:09:21.190
our view of the universe their immense
00:09:21.200 --> 00:09:22.790
gravitational influence affects
00:09:22.800 --> 00:09:24.389
everything from our measurements of the
00:09:24.399 --> 00:09:26.230
cosmic microwave background the
00:09:26.240 --> 00:09:28.350
Afterglow of the Big Bang to our
00:09:28.360 --> 00:09:30.710
calculations of how fast the universe is
00:09:30.720 --> 00:09:33.110
expanding they even act as enormous
00:09:33.120 --> 00:09:35.630
Cosmic lenses bending light from distant
00:09:35.640 --> 00:09:38.190
objects as it travels toward Earth while
00:09:38.200 --> 00:09:39.949
our current models of the universe can
00:09:39.959 --> 00:09:42.310
account for structures like kipu these
00:09:42.320 --> 00:09:44.550
Cosmic Giants won't last forever
00:09:44.560 --> 00:09:46.910
scientists predict that over time these
00:09:46.920 --> 00:09:48.550
super structures will eventually break
00:09:48.560 --> 00:09:51.190
apart into smaller units but for now
00:09:51.200 --> 00:09:53.190
they stand as remarkable Cosmic
00:09:53.200 --> 00:09:55.790
monuments offering us unprecedented
00:09:55.800 --> 00:09:57.550
insights into the largest scale
00:09:57.560 --> 00:09:59.710
architecture of our universe and
00:09:59.720 --> 00:10:01.470
challenging our understanding of how
00:10:01.480 --> 00:10:03.590
such enormous structures could have
00:10:03.600 --> 00:10:05.269
formed in the first
00:10:05.279 --> 00:10:07.710
place in a groundbreaking move that
00:10:07.720 --> 00:10:09.790
brings space exploration into the modern
00:10:09.800 --> 00:10:12.750
