00:00:00.320 --> 00:00:02.310
Welcome to Astronomy Daily. I'm your
00:00:02.320 --> 00:00:04.870
host, Anna. Thanks for joining me today
00:00:04.880 --> 00:00:06.710
as we explore the fascinating world
00:00:06.720 --> 00:00:09.350
beyond our atmosphere. Today's cosmic
00:00:09.360 --> 00:00:11.110
journey takes us from the moon to the
00:00:11.120 --> 00:00:13.509
far reaches of space as we dive into
00:00:13.519 --> 00:00:15.350
some truly remarkable developments in
00:00:15.360 --> 00:00:17.910
astronomy and space exploration. We'll
00:00:17.920 --> 00:00:19.429
be starting close to home with China's
00:00:19.439 --> 00:00:21.349
ambitious plans to construct a nuclear
00:00:21.359 --> 00:00:23.189
power plant on the lunar surface in
00:00:23.199 --> 00:00:25.509
collaboration with Russia, a bold step
00:00:25.519 --> 00:00:27.349
toward establishing a permanent human
00:00:27.359 --> 00:00:29.509
presence on our celestial neighbor. Then
00:00:29.519 --> 00:00:31.109
we'll examine a groundbreaking new
00:00:31.119 --> 00:00:33.190
technology from researchers at the
00:00:33.200 --> 00:00:35.110
University of Arizona that could
00:00:35.120 --> 00:00:37.389
revolutionize our ability to detect
00:00:37.399 --> 00:00:39.830
exoplanets by effectively dimming the
00:00:39.840 --> 00:00:41.430
overwhelming light of their parent
00:00:41.440 --> 00:00:43.830
stars. This coronagraph breakthrough
00:00:43.840 --> 00:00:45.590
might just help us find Earthlike
00:00:45.600 --> 00:00:47.510
planets in habitable zones and
00:00:47.520 --> 00:00:50.229
potentially signs of life. If you're an
00:00:50.239 --> 00:00:52.229
early riser, you're in for a treat this
00:00:52.239 --> 00:00:54.310
week. We'll tell you about a mini planet
00:00:54.320 --> 00:00:56.869
parade happening on April 24th when
00:00:56.879 --> 00:01:00.310
Mercury, Venus, Saturn, Neptune, and our
00:01:00.320 --> 00:01:01.910
moon will cluster together in the
00:01:01.920 --> 00:01:04.549
pre-dawn sky, creating a spectacular
00:01:04.559 --> 00:01:07.109
viewing opportunity for amateur
00:01:07.119 --> 00:01:08.950
astronomers and stargazers. We have
00:01:08.960 --> 00:01:10.950
exciting news about asteroid Vesta,
00:01:10.960 --> 00:01:13.109
which reaches opposition on May 2nd.
00:01:13.119 --> 00:01:15.590
hand. This ancient protolanet will be
00:01:15.600 --> 00:01:17.429
visible even to the naked eye under the
00:01:17.439 --> 00:01:19.670
right conditions with a special viewing
00:01:19.680 --> 00:01:21.350
opportunity coming up when it forms a
00:01:21.360 --> 00:01:23.270
temporary double star with another
00:01:23.280 --> 00:01:25.510
celestial object. Finally, we'll
00:01:25.520 --> 00:01:27.030
celebrate a major milestone as the
00:01:27.040 --> 00:01:29.590
Hubble Space Telescope marks its 35th
00:01:29.600 --> 00:01:31.990
year in orbit. We'll look back at how
00:01:32.000 --> 00:01:33.429
this remarkable instrument has
00:01:33.439 --> 00:01:34.950
transformed our understanding of the
00:01:34.960 --> 00:01:36.390
universe and continues to make
00:01:36.400 --> 00:01:38.149
groundbreaking discoveries after more
00:01:38.159 --> 00:01:41.190
than three decades. So settle in as we
00:01:41.200 --> 00:01:43.190
journey through these cosmic wonders and
00:01:43.200 --> 00:01:44.870
explore the latest developments in our
00:01:44.880 --> 00:01:47.230
ongoing quest to understand the
00:01:47.240 --> 00:01:49.670
universe. In what can only be described
00:01:49.680 --> 00:01:51.429
as one of the most ambitious lunar
00:01:51.439 --> 00:01:54.230
projects since the Apollo era, China has
00:01:54.240 --> 00:01:56.230
revealed plans to develop a nuclear
00:01:56.240 --> 00:01:58.389
power plant on the moon. This
00:01:58.399 --> 00:02:00.230
extraordinary undertaking would support
00:02:00.240 --> 00:02:01.990
the International Lunar Research
00:02:02.000 --> 00:02:04.310
Station, a collaborative effort between
00:02:04.320 --> 00:02:07.190
China and Russia aimed at establishing a
00:02:07.200 --> 00:02:09.669
sustained human presence on our nearest
00:02:09.679 --> 00:02:12.070
celestial neighbor. The announcement
00:02:12.080 --> 00:02:14.070
came during a presentation by a senior
00:02:14.080 --> 00:02:16.869
Chinese space official just last week,
00:02:16.879 --> 00:02:18.790
highlighting the serious intentions
00:02:18.800 --> 00:02:20.710
behind what might otherwise sound like
00:02:20.720 --> 00:02:23.510
science fiction. This nuclear facility
00:02:23.520 --> 00:02:25.350
would provide the consistent power
00:02:25.360 --> 00:02:27.910
needed for long-term lunar operations,
00:02:27.920 --> 00:02:29.510
addressing one of the fundamental
00:02:29.520 --> 00:02:31.270
challenges of maintaining a permanent
00:02:31.280 --> 00:02:34.470
outpost so far from Earth. The timeline
00:02:34.480 --> 00:02:36.229
for this lunar endeavor centers around
00:02:36.239 --> 00:02:39.990
the Changi 8 mission scheduled for 2028.
00:02:40.000 --> 00:02:41.350
This mission will serve as the
00:02:41.360 --> 00:02:43.030
foundation for what China hopes will
00:02:43.040 --> 00:02:45.990
become a permanent manned lunar base by
00:02:46.000 --> 00:02:49.589
2035. The preliminary plans also include
00:02:49.599 --> 00:02:52.150
implementing large-scale solar arrays
00:02:52.160 --> 00:02:53.990
alongside an intricate network of
00:02:54.000 --> 00:02:56.229
pipelines and cables built across the
00:02:56.239 --> 00:02:58.150
lunar surface to distribute heat and
00:02:58.160 --> 00:03:00.470
electricity to the various components of
00:03:00.480 --> 00:03:03.030
the research station. What makes this
00:03:03.040 --> 00:03:05.030
particularly interesting is how China's
00:03:05.040 --> 00:03:07.670
lunar ambitions mirror the timeline of
00:03:07.680 --> 00:03:10.710
NASA's own Aremis program, which aims to
00:03:10.720 --> 00:03:12.710
return American astronauts to the moon
00:03:12.720 --> 00:03:14.949
by 2027.
00:03:14.959 --> 00:03:17.110
We appear to be entering a new era of
00:03:17.120 --> 00:03:19.110
lunar exploration and possibly
00:03:19.120 --> 00:03:21.270
settlement, reminiscent of the space
00:03:21.280 --> 00:03:23.910
race of the 1960s, but with more
00:03:23.920 --> 00:03:25.910
emphasis on establishing long-term
00:03:25.920 --> 00:03:27.910
infrastructure rather than simply
00:03:27.920 --> 00:03:30.630
planting flags. The China Russia
00:03:30.640 --> 00:03:32.710
collaboration is especially notable
00:03:32.720 --> 00:03:34.309
given the current geopolitical
00:03:34.319 --> 00:03:37.190
landscape. Recent Western sanctions have
00:03:37.200 --> 00:03:39.670
significantly limited Russia's access to
00:03:39.680 --> 00:03:41.589
space technology, making this
00:03:41.599 --> 00:03:43.670
partnership strategically valuable for
00:03:43.680 --> 00:03:46.550
both nations. For Russia, it provides
00:03:46.560 --> 00:03:48.229
continued involvement in cuttingedge
00:03:48.239 --> 00:03:50.550
space exploration, while China gains
00:03:50.560 --> 00:03:52.710
access to Russia's decades of experience
00:03:52.720 --> 00:03:55.430
in space operations and technology.
00:03:55.440 --> 00:03:57.030
Building a nuclear power plant on the
00:03:57.040 --> 00:03:58.869
moon presents enormous engineering
00:03:58.879 --> 00:04:00.390
challenges.
00:04:00.400 --> 00:04:01.990
The facility would need to withstand
00:04:02.000 --> 00:04:04.149
extreme temperature variations,
00:04:04.159 --> 00:04:06.070
radiation exposure, and the
00:04:06.080 --> 00:04:08.550
complications of lunar dust, not to
00:04:08.560 --> 00:04:10.149
mention the logistical hurdles of
00:04:10.159 --> 00:04:11.910
transporting construction materials and
00:04:11.920 --> 00:04:15.589
equipment 238,000 m from Earth. Yet, the
00:04:15.599 --> 00:04:17.830
advantages are equally significant.
00:04:17.840 --> 00:04:19.990
Nuclear power offers the high energy
00:04:20.000 --> 00:04:22.069
density and reliability needed for a
00:04:22.079 --> 00:04:24.070
permanent lunar base without the
00:04:24.080 --> 00:04:25.830
limitations of solar power during the
00:04:25.840 --> 00:04:29.110
twoe lunar nights. If successful, this
00:04:29.120 --> 00:04:30.790
endeavor could fundamentally alter
00:04:30.800 --> 00:04:33.030
humanity's relationship with our nearest
00:04:33.040 --> 00:04:35.110
celestial neighbor, transforming the
00:04:35.120 --> 00:04:37.590
moon from a destination for brief visits
00:04:37.600 --> 00:04:39.670
to a place where people may one day live
00:04:39.680 --> 00:04:42.469
and work for extended periods. It also
00:04:42.479 --> 00:04:44.230
raises fascinating questions about
00:04:44.240 --> 00:04:47.270
international cooperation, competition,
00:04:47.280 --> 00:04:49.270
and the potential commercialization of
00:04:49.280 --> 00:04:52.790
lunar resources in the decades ahead.
00:04:52.800 --> 00:04:55.270
Next up today, imagine being able to see
00:04:55.280 --> 00:04:57.430
a planet a billion times dimmer than its
00:04:57.440 --> 00:05:00.870
star. It sounds impossible, right? Well,
00:05:00.880 --> 00:05:02.870
researchers at the University of Arizona
00:05:02.880 --> 00:05:05.189
have developed a breakthrough technology
00:05:05.199 --> 00:05:07.029
that might just make this seemingly
00:05:07.039 --> 00:05:09.430
impossible feat a reality. Their
00:05:09.440 --> 00:05:11.110
innovative coronagraph design could
00:05:11.120 --> 00:05:13.110
revolutionize how we detect exoplanets
00:05:13.120 --> 00:05:14.469
by effectively turning down the
00:05:14.479 --> 00:05:16.590
overwhelming brightness of their parent
00:05:16.600 --> 00:05:19.270
stars. Lead researcher Nico Dashler
00:05:19.280 --> 00:05:21.590
explained the fundamental challenge.
00:05:21.600 --> 00:05:24.310
Earthlike planets in the habitable zone
00:05:24.320 --> 00:05:26.390
can easily be up to a billion times
00:05:26.400 --> 00:05:28.510
dimmer than their host
00:05:28.520 --> 00:05:31.350
star. This extreme brightness difference
00:05:31.360 --> 00:05:33.670
has been a persistent obstacle in our
00:05:33.680 --> 00:05:35.590
quest to directly observe potentially
00:05:35.600 --> 00:05:38.390
habitable worlds. When a planet is so
00:05:38.400 --> 00:05:40.790
drastically outshined, it's like trying
00:05:40.800 --> 00:05:42.870
to spot a firefly next to a stadium
00:05:42.880 --> 00:05:45.590
flood light. The team's solution
00:05:45.600 --> 00:05:47.830
published in the journal Optica is
00:05:47.840 --> 00:05:50.629
remarkably elegant. Their coronagraph
00:05:50.639 --> 00:05:52.469
essentially siphons away the starlight
00:05:52.479 --> 00:05:54.310
that would normally overwhelm the faint
00:05:54.320 --> 00:05:57.110
light from nearby exoplanets. What makes
00:05:57.120 --> 00:05:59.189
this approach particularly exciting is
00:05:59.199 --> 00:06:01.029
that it can reach what scientists call
00:06:01.039 --> 00:06:03.189
quantum optical limits for exoplanet
00:06:03.199 --> 00:06:05.350
detection, pushing the boundaries of
00:06:05.360 --> 00:06:08.070
what we previously thought possible. In
00:06:08.080 --> 00:06:09.430
laboratory testing, the team
00:06:09.440 --> 00:06:11.189
demonstrated that their system could
00:06:11.199 --> 00:06:13.070
identify the positions of synthetic
00:06:13.080 --> 00:06:15.110
exoplanets much closer to their
00:06:15.120 --> 00:06:17.270
artificial host stars than standard
00:06:17.280 --> 00:06:19.909
resolution limits would normally allow.
00:06:19.919 --> 00:06:22.070
This capability is critical because the
00:06:22.080 --> 00:06:24.150
most interesting planets, those
00:06:24.160 --> 00:06:26.550
potentially capable of supporting life,
00:06:26.560 --> 00:06:28.469
tend to orbit in close proximity to
00:06:28.479 --> 00:06:30.790
their stars. The technology relies on
00:06:30.800 --> 00:06:32.629
what scientists call spatial mode
00:06:32.639 --> 00:06:34.950
sorting. Think of light from different
00:06:34.960 --> 00:06:37.029
sources in space as creating distinct
00:06:37.039 --> 00:06:39.070
patterns similar to different notes on a
00:06:39.080 --> 00:06:41.749
piano. The coronagraph uses a mode
00:06:41.759 --> 00:06:43.590
sorter to filter out the overwhelming
00:06:43.600 --> 00:06:45.670
starlight, followed by an inverse mode
00:06:45.680 --> 00:06:47.670
sorter to reconstruct the image,
00:06:47.680 --> 00:06:49.670
allowing the exoplanet's light to emerge
00:06:49.680 --> 00:06:52.469
with remarkable clarity. What separates
00:06:52.479 --> 00:06:53.909
this approach from other detection
00:06:53.919 --> 00:06:55.909
methods is that it captures direct
00:06:55.919 --> 00:06:58.309
images rather than inferring a planet's
00:06:58.319 --> 00:07:01.029
existence through indirect means. Our
00:07:01.039 --> 00:07:02.870
coronagraph directly captures an image
00:07:02.880 --> 00:07:05.749
of the exoplanet. Desler noted images
00:07:05.759 --> 00:07:07.670
can provide context and composition
00:07:07.680 --> 00:07:09.350
information that can be used to
00:07:09.360 --> 00:07:11.749
determine exoplanet orbits and identify
00:07:11.759 --> 00:07:13.950
other objects that scatter light from a
00:07:13.960 --> 00:07:16.950
star. To validate their concept, the
00:07:16.960 --> 00:07:18.710
researchers constructed a laboratory
00:07:18.720 --> 00:07:21.510
setup mimicking a star exoplanet system
00:07:21.520 --> 00:07:25.189
with a 1,00 to1 brightness contrast. By
00:07:25.199 --> 00:07:26.790
simulating the planet's orbit and
00:07:26.800 --> 00:07:28.950
capturing images frame by frame, they
00:07:28.960 --> 00:07:30.790
were able to pinpoint its position at
00:07:30.800 --> 00:07:32.469
separations previously considered
00:07:32.479 --> 00:07:35.110
impossible to resolve. The implications
00:07:35.120 --> 00:07:37.270
of this technology extend far beyond
00:07:37.280 --> 00:07:39.430
just finding planets. If this
00:07:39.440 --> 00:07:41.670
coronagraph can be refined and scaled up
00:07:41.680 --> 00:07:44.469
for astronomical observatories, it could
00:07:44.479 --> 00:07:46.550
potentially allow scientists to analyze
00:07:46.560 --> 00:07:49.189
the atmospheres of Earthlike exoplanets,
00:07:49.199 --> 00:07:51.830
for bio signatures, chemical indicators
00:07:51.840 --> 00:07:53.589
that might reveal the presence of life
00:07:53.599 --> 00:07:56.230
beyond our solar system. The timing
00:07:56.240 --> 00:07:57.749
couldn't be better as NASA has
00:07:57.759 --> 00:08:00.150
prioritized exoplanet discovery with its
00:08:00.160 --> 00:08:02.629
planned habitable worlds observatory.
00:08:02.639 --> 00:08:04.390
This next generation space telescope
00:08:04.400 --> 00:08:06.070
will specifically target potentially
00:08:06.080 --> 00:08:08.469
habitable exoplanets and technologies
00:08:08.479 --> 00:08:10.550
like this advanced coronagraph could be
00:08:10.560 --> 00:08:12.869
instrumental to its success. The
00:08:12.879 --> 00:08:14.790
research team is now working to refine
00:08:14.800 --> 00:08:17.270
their spatial mode sorter to reduce what
00:08:17.280 --> 00:08:19.830
they call optical cross talk essentially
00:08:19.840 --> 00:08:21.909
light leakage between channels that can
00:08:21.919 --> 00:08:24.309
contaminate the results. While
00:08:24.319 --> 00:08:26.029
manageable in moderate contrast
00:08:26.039 --> 00:08:28.230
scenarios, the extreme brightness
00:08:28.240 --> 00:08:30.629
differences in exoplanet studies demand
00:08:30.639 --> 00:08:33.350
exceptional light isolation. Beyond
00:08:33.360 --> 00:08:35.269
astronomy, the techniques developed for
00:08:35.279 --> 00:08:37.269
this coronagraph could have applications
00:08:37.279 --> 00:08:39.870
in other fields like quantum sensing,
00:08:39.880 --> 00:08:42.790
communications, and advanced imaging.
00:08:42.800 --> 00:08:44.790
It's yet another example of how the
00:08:44.800 --> 00:08:47.470
quest to explore other worlds drives
00:08:47.480 --> 00:08:49.990
innovation that benefits multiple
00:08:50.000 --> 00:08:52.790
scientific disciplines.
00:08:52.800 --> 00:08:55.269
Early birds, mark your calendars. An
00:08:55.279 --> 00:08:57.110
exceptional celestial event is about to
00:08:57.120 --> 00:08:59.990
grace our pre-dawn skies on April 24th
00:09:00.000 --> 00:09:01.990
when a striking mini planetary parade
00:09:02.000 --> 00:09:04.150
will unfold, featuring Mercury, Venus,
00:09:04.160 --> 00:09:06.470
Saturn, Neptune, and Earth's moon, all
00:09:06.480 --> 00:09:07.990
clustering in the same region of the
00:09:08.000 --> 00:09:10.710
sky. This cosmic alignment offers a rare
00:09:10.720 --> 00:09:12.550
and beautiful photo opportunity for
00:09:12.560 --> 00:09:14.710
astronomy enthusiasts and early risers
00:09:14.720 --> 00:09:16.790
alike. What makes these planetary
00:09:16.800 --> 00:09:18.710
alignments so fascinating is the
00:09:18.720 --> 00:09:20.870
illusion they create, though separated
00:09:20.880 --> 00:09:22.710
by hundreds of millions of miles in
00:09:22.720 --> 00:09:25.190
space, their orbital positions will
00:09:25.200 --> 00:09:27.230
temporarily align from our earthly
00:09:27.240 --> 00:09:29.190
perspective, making them appear
00:09:29.200 --> 00:09:32.070
remarkably close together in our sky. To
00:09:32.080 --> 00:09:34.230
witness this celestial gathering, you'll
00:09:34.240 --> 00:09:36.550
need to set your alarm clock early. Look
00:09:36.560 --> 00:09:39.590
toward the eastern horizon around 5:15
00:09:39.600 --> 00:09:41.829
a.m. local time, where you'll first spot
00:09:41.839 --> 00:09:44.870
the moon as a thin, waning crescent,
00:09:44.880 --> 00:09:47.030
approaching its new moon phase that will
00:09:47.040 --> 00:09:49.590
arrive on April 27th. Its delicate,
00:09:49.600 --> 00:09:51.509
slender form will be hovering low on the
00:09:51.519 --> 00:09:53.670
horizon, creating a stunning visual
00:09:53.680 --> 00:09:55.389
anchor for the planetary
00:09:55.399 --> 00:09:57.509
procession. Directly to the left of the
00:09:57.519 --> 00:09:59.110
moon, you'll find Venus shining
00:09:59.120 --> 00:10:02.150
brilliantly as our current morning star.
00:10:02.160 --> 00:10:03.829
Venus has recently transitioned to
00:10:03.839 --> 00:10:05.430
morning visibility following its
00:10:05.440 --> 00:10:08.310
inferior solar conjunction on March 23rd
00:10:08.320 --> 00:10:09.990
when it passed between Earth and the
00:10:10.000 --> 00:10:12.070
Sun, ending its appearance in our
00:10:12.080 --> 00:10:15.269
evening skies. Saturn can be located by
00:10:15.279 --> 00:10:16.870
looking slightly down and to the right
00:10:16.880 --> 00:10:19.590
of Venus. The ringed planet will appear
00:10:19.600 --> 00:10:22.310
as a steady yellowish point of light.
00:10:22.320 --> 00:10:24.389
Mercury will be the last of the easily
00:10:24.399 --> 00:10:27.110
visible planets to rise, requiring a
00:10:27.120 --> 00:10:29.829
clear, unobstructed eastern horizon to
00:10:29.839 --> 00:10:31.990
be spotted before sunrise. swallows it
00:10:32.000 --> 00:10:35.190
in growing daylight. Neptune, the most
00:10:35.200 --> 00:10:37.509
distant world in this cosmic lineup,
00:10:37.519 --> 00:10:39.350
will be nestled in the center of this
00:10:39.360 --> 00:10:41.910
planetary triangle. However, at
00:10:41.920 --> 00:10:45.190
magnitude 7.9, this ice giant will
00:10:45.200 --> 00:10:47.990
remain invisible to the naked eye. Those
00:10:48.000 --> 00:10:50.150
hoping to glimpse Neptune's pale blue
00:10:50.160 --> 00:10:52.710
green disc will need a telescope or
00:10:52.720 --> 00:10:54.949
powerful binoculars.
00:10:54.959 --> 00:10:56.949
This April alignment follows February's
00:10:56.959 --> 00:10:59.269
more expansive planetary parade, which
00:10:59.279 --> 00:11:01.190
featured all five of our solar systems
00:11:01.200 --> 00:11:04.550
brightest planets, Venus, Jupiter, Mars,
00:11:04.560 --> 00:11:07.110
Saturn, and Mercury, plus the ice giants
00:11:07.120 --> 00:11:09.670
Neptune and Uranus. While this week's
00:11:09.680 --> 00:11:12.069
gathering is more modest in scale, the
00:11:12.079 --> 00:11:13.750
addition of the waning crescent moon
00:11:13.760 --> 00:11:15.829
adds a particularly photogenic element
00:11:15.839 --> 00:11:18.470
that photographers won't want to miss.
00:11:18.480 --> 00:11:19.829
If you're planning to capture this
00:11:19.839 --> 00:11:21.750
celestial event, be sure to scout a
00:11:21.760 --> 00:11:24.310
location with a clear eastern horizon,
00:11:24.320 --> 00:11:26.190
free from obstructions and light
00:11:26.200 --> 00:11:28.230
pollution. Remember that observing
00:11:28.240 --> 00:11:30.949
objects near the horizon often requires
00:11:30.959 --> 00:11:33.269
patience as atmospheric conditions can
00:11:33.279 --> 00:11:36.310
affect visibility. And always exercise
00:11:36.320 --> 00:11:38.630
caution when viewing celestial objects
00:11:38.640 --> 00:11:41.350
near sunrise. Never look directly at the
00:11:41.360 --> 00:11:44.150
sun without proper solar filters.
00:11:44.160 --> 00:11:46.310
This mini planetary parade is just one
00:11:46.320 --> 00:11:48.630
of many astronomical treats visible this
00:11:48.640 --> 00:11:51.110
northern spring, offering a perfect
00:11:51.120 --> 00:11:52.949
opportunity to connect with our cosmic
00:11:52.959 --> 00:11:55.190
neighborhood before dawn breaks on an
00:11:55.200 --> 00:11:57.190
ordinary Wednesday that will briefly
00:11:57.200 --> 00:11:58.949
become extraordinary for those who know
00:11:58.959 --> 00:11:59.870
where to
00:11:59.880 --> 00:12:02.310
look. And while you're in the mood to be
00:12:02.320 --> 00:12:04.550
looking up, here's another treat for
00:12:04.560 --> 00:12:07.269
you. While most asteroids remain dim
00:12:07.279 --> 00:12:09.590
specs visible only through telescopes,
00:12:09.600 --> 00:12:12.030
Asteroid Vesta is quite the celestial
00:12:12.040 --> 00:12:14.470
standout. Reaching opposition on May
00:12:14.480 --> 00:12:17.430
2nd, Vesta will achieve peak brightness,
00:12:17.440 --> 00:12:19.670
becoming visible even to the naked eye
00:12:19.680 --> 00:12:21.710
if you're observing from a dark sky
00:12:21.720 --> 00:12:24.150
location. This remarkable visibility
00:12:24.160 --> 00:12:27.110
isn't just a coincidence. Vesta occupies
00:12:27.120 --> 00:12:29.269
a unique position in our solar system as
00:12:29.279 --> 00:12:31.990
both asteroid and protolanet. NASA's
00:12:32.000 --> 00:12:34.389
Dawn mission, which orbited Vesta for 14
00:12:34.399 --> 00:12:37.430
months between 2011 and 2012, revealed
00:12:37.440 --> 00:12:39.430
fascinating details about this enigmatic
00:12:39.440 --> 00:12:41.590
world. Its surface contains highly
00:12:41.600 --> 00:12:43.509
reflective basaltic rock alongside
00:12:43.519 --> 00:12:45.509
darker carbonatous material delivered by
00:12:45.519 --> 00:12:48.310
meteorite impacts. What makes Vesta
00:12:48.320 --> 00:12:50.949
truly special is its unusual brightness,
00:12:50.959 --> 00:12:53.110
which scientists now believe stems from
00:12:53.120 --> 00:12:54.750
its early planetary
00:12:54.760 --> 00:12:57.670
development. A 2012 study of a Vesta
00:12:57.680 --> 00:12:59.910
meteorite discovered evidence of an
00:12:59.920 --> 00:13:02.790
ancient magnetic field that existed 3.7
00:13:02.800 --> 00:13:05.590
billion years ago. This confirms that
00:13:05.600 --> 00:13:07.509
Vesta is one of the few confirmed
00:13:07.519 --> 00:13:09.990
protolanets in our solar system. During
00:13:10.000 --> 00:13:12.230
its embionic planetary phase more than 4
00:13:12.240 --> 00:13:14.629
billion years ago, Vesta's interior was
00:13:14.639 --> 00:13:16.629
hot enough to melt and differentiate
00:13:16.639 --> 00:13:19.350
into distinct layers, a metallic iron
00:13:19.360 --> 00:13:22.710
core, dense mantle, and outer crust. The
00:13:22.720 --> 00:13:24.790
molten metal within its core generated
00:13:24.800 --> 00:13:27.350
an asteroidwide magnetic field that
00:13:27.360 --> 00:13:29.430
likely shielded Vesta's surface from the
00:13:29.440 --> 00:13:31.190
solar wind and cosmic rays that
00:13:31.200 --> 00:13:32.870
typically darken surface minerals
00:13:32.880 --> 00:13:34.389
through a process called space
00:13:34.399 --> 00:13:37.030
weathering. This protective magnetic
00:13:37.040 --> 00:13:38.949
field may explain why Vesta maintains
00:13:38.959 --> 00:13:41.190
its radiant appearance today, making it
00:13:41.200 --> 00:13:43.230
an accessible target for amateur
00:13:43.240 --> 00:13:45.350
astronomers. Currently shining at a
00:13:45.360 --> 00:13:48.470
robust magnitude 5.7, Vesta is tracking
00:13:48.480 --> 00:13:50.550
from northern Libra into Virgo this
00:13:50.560 --> 00:13:53.030
month and next. Even modest pocket
00:13:53.040 --> 00:13:55.590
binoculars will reveal its presence. For
00:13:55.600 --> 00:13:57.350
those hoping to spot Vesta without
00:13:57.360 --> 00:14:00.550
optical aid, try this technique. First,
00:14:00.560 --> 00:14:02.629
confirm its position with binoculars.
00:14:02.639 --> 00:14:04.629
Then use nearby stars to create a
00:14:04.639 --> 00:14:06.310
distinctive pattern that includes the
00:14:06.320 --> 00:14:09.350
asteroid. By employing averted vision,
00:14:09.360 --> 00:14:10.870
looking slightly to the side of your
00:14:10.880 --> 00:14:13.110
target rather than directly at it, you
00:14:13.120 --> 00:14:15.750
can gradually coax Vesta into view. The
00:14:15.760 --> 00:14:19.350
2.6 magnitude star Beta Libé, also known
00:14:19.360 --> 00:14:21.910
as Zubaneshali, and fourth magnitude
00:14:21.920 --> 00:14:23.829
Mujanice provide useful reference
00:14:23.839 --> 00:14:25.189
points.
00:14:25.199 --> 00:14:27.030
Stargazers have a special opportunity
00:14:27.040 --> 00:14:30.389
from April 23rd through 27th when Vesta
00:14:30.399 --> 00:14:33.030
will lie within just 35 arc minutes of
00:14:33.040 --> 00:14:37.430
the 4.5 magnitude star 16 library. As
00:14:37.440 --> 00:14:39.590
Vesta slides northwest in retrograde
00:14:39.600 --> 00:14:42.310
motion, it will form a temporary double
00:14:42.320 --> 00:14:45.430
star with its stellar companion. This
00:14:45.440 --> 00:14:47.269
alignment makes locating the asteroid
00:14:47.279 --> 00:14:49.269
particularly easy while also
00:14:49.279 --> 00:14:50.990
highlighting its nightto-ightight
00:14:51.000 --> 00:14:54.790
movement. On April 25th and 26th, the
00:14:54.800 --> 00:14:57.030
pair will be separated by a mere 10 ark
00:14:57.040 --> 00:14:59.030
minutes. The night before this close
00:14:59.040 --> 00:15:01.910
approach, Vesta forms a compact nearly
00:15:01.920 --> 00:15:05.870
linear trio with 16 Libri and HD13
00:15:05.880 --> 00:15:09.750
23rd75, a magnitude 6.1 star located 45
00:15:09.760 --> 00:15:12.230
ark minutes to its southeast. These
00:15:12.240 --> 00:15:14.310
alignments offer perfect opportunities
00:15:14.320 --> 00:15:16.949
to track this ancient protolanet as it
00:15:16.959 --> 00:15:19.509
continues its journey around our sun,
00:15:19.519 --> 00:15:21.269
carrying with it the secrets of our
00:15:21.279 --> 00:15:22.990
solar systems early
00:15:23.000 --> 00:15:25.189
formation. And let's wrap up today's
00:15:25.199 --> 00:15:27.829
episode with a celebration. This April
00:15:27.839 --> 00:15:29.829
marks a truly remarkable milestone in
00:15:29.839 --> 00:15:32.470
space exploration as NASA celebrates the
00:15:32.480 --> 00:15:34.710
Hubble Space Telescope's 35th year in
00:15:34.720 --> 00:15:36.949
Earth orbit. To commemorate this
00:15:36.959 --> 00:15:38.949
incredible achievement, NASA is
00:15:38.959 --> 00:15:40.870
releasing a collection of stunning new
00:15:40.880 --> 00:15:43.110
images capturing everything from our
00:15:43.120 --> 00:15:45.990
planetary neighbor Mars to distant star
00:15:46.000 --> 00:15:47.949
forming regions and neighboring
00:15:47.959 --> 00:15:50.389
galaxies. After more than three decades
00:15:50.399 --> 00:15:52.629
of peering into the cosmos, Hubble
00:15:52.639 --> 00:15:55.590
remains not just relevant but iconic.
00:15:55.600 --> 00:15:57.910
The most recognized and scientifically
00:15:57.920 --> 00:16:01.030
productive telescope in human history.
00:16:01.040 --> 00:16:03.110
The Hubble mission stands as a glowing
00:16:03.120 --> 00:16:05.030
testament to American technological
00:16:05.040 --> 00:16:07.829
prowess, scientific curiosity, and
00:16:07.839 --> 00:16:11.310
pioneering spirit. Launched on April 24,
00:16:11.320 --> 00:16:14.870
1990, the 24,000lb observatory was
00:16:14.880 --> 00:16:16.710
delivered to orbit tucked inside the
00:16:16.720 --> 00:16:19.670
space shuttle Discovery's cargo bay. At
00:16:19.680 --> 00:16:21.990
the time, NASA commentators described
00:16:22.000 --> 00:16:25.030
Hubble as a new window on the universe,
00:16:25.040 --> 00:16:26.870
a promise the telescope has fulfilled
00:16:26.880 --> 00:16:30.069
beyond anyone's wildest expectations.
00:16:30.079 --> 00:16:31.670
The telescope's journey hasn't been
00:16:31.680 --> 00:16:32.509
without
00:16:32.519 --> 00:16:34.629
challenges. Shortly after launch,
00:16:34.639 --> 00:16:36.790
engineers discovered an unexpected flaw
00:16:36.800 --> 00:16:39.269
in Hubble's nearly 8ft diameter primary
00:16:39.279 --> 00:16:41.430
mirror. This early setback was
00:16:41.440 --> 00:16:43.430
dramatically overcome when astronauts
00:16:43.440 --> 00:16:45.189
performed the first shuttle servicing
00:16:45.199 --> 00:16:48.069
mission in December 1993, installing
00:16:48.079 --> 00:16:50.069
corrective optics that restored Hubble's
00:16:50.079 --> 00:16:52.150
intended sharpness.
00:16:52.160 --> 00:16:54.389
Over the years, astronauts returned to
00:16:54.399 --> 00:16:57.030
Hubble four more times, upgrading its
00:16:57.040 --> 00:16:59.030
cameras, computers, and support systems
00:16:59.040 --> 00:17:00.949
during servicing missions that continued
00:17:00.959 --> 00:17:01.949
until
00:17:01.959 --> 00:17:04.630
2009. The numbers behind Hubble's legacy
00:17:04.640 --> 00:17:07.270
are staggering. To date, the telescope
00:17:07.280 --> 00:17:10.309
has made nearly 1.7 million observations
00:17:10.319 --> 00:17:12.630
targeting approximately 55,000
00:17:12.640 --> 00:17:15.510
astronomical objects. These observations
00:17:15.520 --> 00:17:17.909
have resulted in over 22,000 scientific
00:17:17.919 --> 00:17:19.990
papers and more than 1.3 million
00:17:20.000 --> 00:17:22.710
citations. The data collected by Hubble
00:17:22.720 --> 00:17:25.829
currently totals over 400 terabytes, the
00:17:25.839 --> 00:17:27.669
largest data set for any NASA
00:17:27.679 --> 00:17:29.430
astrophysics mission aside from the
00:17:29.440 --> 00:17:30.909
James Web Space
00:17:30.919 --> 00:17:33.350
Telescope. Hubble's long operational
00:17:33.360 --> 00:17:35.029
life has given astronomers the
00:17:35.039 --> 00:17:37.430
unprecedented ability to observe cosmic
00:17:37.440 --> 00:17:39.590
changes occurring over decades. From
00:17:39.600 --> 00:17:41.510
seasonal variations on planets in our
00:17:41.520 --> 00:17:43.510
solar system to black hole jets
00:17:43.520 --> 00:17:45.990
traveling at nearly light speed, stellar
00:17:46.000 --> 00:17:48.710
convulsions, asteroid collisions, and
00:17:48.720 --> 00:17:50.950
expanding supernova remnants. The
00:17:50.960 --> 00:17:52.789
telescope's impact on our understanding
00:17:52.799 --> 00:17:55.669
of the universe cannot be overstated.
00:17:55.679 --> 00:17:57.909
Before Hubble, powerful groundbased
00:17:57.919 --> 00:17:59.830
telescopes could see only halfway across
00:17:59.840 --> 00:18:01.990
the cosmos, and estimates for the
00:18:02.000 --> 00:18:05.110
universe's age varied widely. super
00:18:05.120 --> 00:18:06.710
massive black holes were merely
00:18:06.720 --> 00:18:09.350
suspected to exist and no planets had
00:18:09.360 --> 00:18:12.150
been detected around other stars. Among
00:18:12.160 --> 00:18:14.390
Hubble's groundbreaking achievements,
00:18:14.400 --> 00:18:16.710
its deep field images revealed countless
00:18:16.720 --> 00:18:18.470
galaxies dating back to the early
00:18:18.480 --> 00:18:20.710
universe. It allowed scientists to
00:18:20.720 --> 00:18:22.390
precisely measure the universe's
00:18:22.400 --> 00:18:24.870
expansion rate. It confirmed that super
00:18:24.880 --> 00:18:26.909
massive black holes are common among
00:18:26.919 --> 00:18:29.270
galaxies, and it enabled the first
00:18:29.280 --> 00:18:32.230
measurements of exoplanet atmospheres.
00:18:32.240 --> 00:18:34.470
Perhaps most significantly, Hubble
00:18:34.480 --> 00:18:36.230
contributed to the discovery of dark
00:18:36.240 --> 00:18:38.470
energy, the mysterious force
00:18:38.480 --> 00:18:40.470
accelerating the universe's expansion
00:18:40.480 --> 00:18:43.870
work that led to the 2011 Nobel Prize in
00:18:43.880 --> 00:18:46.510
physics. The telescope's continued
00:18:46.520 --> 00:18:49.270
productivity has inspired and paved the
00:18:49.280 --> 00:18:51.789
way for a new generation of space
00:18:51.799 --> 00:18:54.070
observatories. Hubble provided the first
00:18:54.080 --> 00:18:56.150
evidence of the distant galaxies that
00:18:56.160 --> 00:18:58.150
the James Web Space Telescope now
00:18:58.160 --> 00:19:00.789
studies in infrared wavelengths.
00:19:00.799 --> 00:19:03.190
Today, the two observatories often work
00:19:03.200 --> 00:19:05.350
in tandem, complementing each other's
00:19:05.360 --> 00:19:07.350
capabilities to study everything from
00:19:07.360 --> 00:19:10.310
exoplanets to galaxy evolution. Looking
00:19:10.320 --> 00:19:12.870
ahead, Hubble's planned successor, the
00:19:12.880 --> 00:19:14.950
Habitable World's Observatory, will
00:19:14.960 --> 00:19:17.270
feature a significantly larger mirror
00:19:17.280 --> 00:19:19.669
for observing invisible and ultraviolet
00:19:19.679 --> 00:19:21.990
light. It will be notably sharper than
00:19:22.000 --> 00:19:24.390
Hubble and up to 100 times more
00:19:24.400 --> 00:19:26.710
sensitive to starlight with a major goal
00:19:26.720 --> 00:19:28.630
of identifying potentially habitable
00:19:28.640 --> 00:19:30.990
terrestrial planets around neighboring
00:19:31.000 --> 00:19:33.430
stars. As Hubble continues making
00:19:33.440 --> 00:19:35.110
groundbreaking discoveries that shape
00:19:35.120 --> 00:19:36.870
our fundamental understanding of the
00:19:36.880 --> 00:19:39.750
universe, its legacy as humanity's most
00:19:39.760 --> 00:19:41.909
successful space telescope remains
00:19:41.919 --> 00:19:44.150
secure. A remarkable scientific
00:19:44.160 --> 00:19:46.310
instrument that has truly changed how we
00:19:46.320 --> 00:19:49.510
see our place in the cosmos.
00:19:49.520 --> 00:19:51.190
And that brings us to the end of today's
00:19:51.200 --> 00:19:53.830
cosmic journey on Astronomy Daily. What
00:19:53.840 --> 00:19:55.909
