Transcript
- 0:00Welcome [music] to Astronomy Daily, your
- 0:02source for the latest space and
- 0:04astronomy news. I'm Anna.
- 0:06>> And I'm Avery. It's Monday, February
- 0:08[music] 2nd, 2026, and we've got a
- 0:11fantastic lineup of stories today,
- 0:13exploring [music] everything from
- 0:14SpaceX's audacious satellite plans to
- 0:17ancient star maps hidden for centuries.
- 0:20That's right, Avery. Today, we're diving
- 0:22into SpaceX's jaw-dropping proposal to
- 0:25launch up to 1 million solar [music]
- 0:27powered satellites. A remarkable
- 0:29archaeological discovery revealing
- 0:31Hipparcus' lost [music] star catalog and
- 0:34China's ambitious solar monitoring
- 0:36mission heading to a unique point in
- 0:39space. We'll also be discussing the
- 0:41[music] giant star that fooled
- 0:42astronomers worldwide, Time magazine
- 0:45special tribute to the Aremis 2 crew,
- 0:47and remembering Glattis West, a hidden
- 0:49figure who helps shape GPS [music]
- 0:51technology. It's going to be an
- 0:53incredible journey through space
- 0:54history, present, and future. So settle
- 0:58in and let's explore the cosmos
- 1:00together.
- 1:01>> We're starting with what might be the
- 1:02most ambitious satellite constellation
- 1:04proposal ever conceived. SpaceX has
- 1:07filed with the Federal Communications
- 1:09Commission seeking approval to launch up
- 1:11to 1 million solar powered satellites
- 1:14that would function as data centers for
- 1:16artificial intelligence.
- 1:18>> 1 million satellites, Avery. That's
- 1:20absolutely staggering. To put that in
- 1:23perspective, there are currently around
- 1:2515,000 man-made satellites orbiting
- 1:28Earth, according to the European Space
- 1:30Agency. SpaceX is essentially proposing
- 1:32to increase that number by several
- 1:35orders of magnitude.
- 1:36>> The scale is mind-boggling, Anna, and
- 1:38SpaceX isn't just framing this as a
- 1:40commercial venture. Their filing
- 1:42describes these satellites as the most
- 1:44efficient way to meet accelerating
- 1:46demand for AI computing power, but they
- 1:48go even further. They're calling it a
- 1:50first step towards becoming a
- 1:51Cardartesev type 2 civilization. One
- 1:54that can harness the sun's full power.
- 1:56>> That's quite the vision. For our
- 1:58listeners who might not be familiar, the
- 2:00Cardev scale is a method of measuring a
- 2:03civilization's technological advancement
- 2:06based on energy consumption. A type 2
- 2:08civilization would be able to harness
- 2:10all the energy output of its star. But
- 2:13let's talk practicalities here. The
- 2:15Verge has pointed out that the 1 million
- 2:18satellite number is unlikely to be
- 2:20approved outright and is probably a
- 2:22starting point for negotiation.
- 2:24>> Exactly. The FCC recently gave SpaceX
- 2:27permission to launch an additional 7,575
- 2:31Starlink satellites, but deferred
- 2:33authorization on the remaining 14,988
- 2:37satellites proposed. So there's clearly
- 2:40regulatory caution about satellite
- 2:41proliferation and there are very real
- 2:44concerns about space debris and light
- 2:45pollution that come with such massive
- 2:47constellations. The timing is also
- 2:50interesting. This filing comes as Amazon
- 2:52is seeking an FCC extension on a
- 2:55deadline to have more than 1,600
- 2:57satellites in orbit citing a lack of
- 3:00available rockets. Meanwhile, SpaceX is
- 3:03reportedly considering a merger with two
- 3:05of Elon Musk's other companies, Tesla
- 3:07and XAI, ahead of going public.
- 3:10>> It really shows how the commercial space
- 3:12sector is evolving. Anna, what was once
- 3:14the domain of governments is
- 3:15increasingly being driven by private
- 3:17companies with enormous ambitions.
- 3:19Whether SpaceX gets approval for
- 3:21anything close to a million satellites
- 3:23remains to be seen, but it certainly
- 3:25signals where they think the future is
- 3:27headed. It's fascinating to think about,
- 3:30but we'll have to see how regulators
- 3:31balance innovation with the very real
- 3:34concerns about our orbital environment.
- 3:36Now, let's move from the future to the
- 3:38distant past. From cuttingedge satellite
- 3:41technology, we're traveling back more
- 3:43than 2,000 years to rediscover one of
- 3:45astronomy's greatest lost treasures.
- 3:48Scientists have successfully recovered
- 3:50fragments of the world's earliest star
- 3:52catalog created by the ancient Greek
- 3:54astronomer Hipparus from a 1500year-old
- 3:57manuscript. This is absolutely
- 4:00remarkable. Avery Hipparus is widely
- 4:02considered the father of astronomy. He
- 4:05figured out how equinoxes shift, created
- 4:07a magnitude scale to rank star
- 4:09brightness, and tracked planetary motion
- 4:12all more than 2,000 years ago without
- 4:15any telescopes. But his actual star
- 4:17catalog had vanished from history until
- 4:20now.
- 4:21>> The manuscript is what's called a
- 4:23palumst, which means it's parchment that
- 4:26was wiped clean and reused. In this
- 4:28case, Hipparkus' original Greek text was
- 4:31erased and overwritten with Syriak
- 4:33religious writings of St. John Clamicus.
- 4:35The original work was literally buried
- 4:37under six layers of ink.
- 4:40>> So, how did researchers manage to read
- 4:42text that was intentionally erased
- 4:44centuries ago? They used some pretty
- 4:47sophisticated technology. A team led by
- 4:50Victor Gizenberg from Sorbon University
- 4:53used X-ray technology at the SALC
- 4:55National Accelerator Laboratory to scan
- 4:5811 pages of the manuscript.
- 5:01>> The key was that Hypocus original ink
- 5:03had a different chemical composition
- 5:05than the later religious texts. The
- 5:07ancient ink was rich in calcium which
- 5:09showed up clearly under X-ray scanning.
- 5:12They used extremely short X-ray pulses,
- 5:14each just 10 milliseconds long, focused
- 5:17on areas no wider than a human air.
- 5:20>> And what they found is remarkable. These
- 5:23aren't just historical curiosities. The
- 5:25star positions Hipparus recorded are
- 5:28incredibly accurate for naked eye
- 5:30observations. As Gizenberg said, the
- 5:32coordinates they're finding are
- 5:34incredibly accurate for something done
- 5:36with the naked eye. This gives us a
- 5:38window into how ancient people
- 5:40understood and mapped the night sky.
- 5:42>> It's also a testament to early
- 5:44scientific thinking. Hipparcus was
- 5:46working without any optical instruments.
- 5:49Yet, he was able to create precise
- 5:51astronomical measurements that laid the
- 5:53foundation for future astronomers. This
- 5:55discovery published in the journal for
- 5:57the history of astronomy helps us answer
- 6:00fundamental questions about the birth of
- 6:02science itself. And the manuscript now
- 6:05held at the Museum of the Bible in
- 6:07Washington DC is so delicate it had to
- 6:10be handcarried in climate controlled
- 6:12boxes to the laboratory. It's wonderful
- 6:14that modern technology can help us
- 6:16recover these ancient insights. Speaking
- 6:19of technology and new vantage points,
- 6:21let's turn to China's upcoming solar
- 6:24mission. China is making major strides
- 6:26in solar exploration with plans to
- 6:28launch its first ever solar probe to the
- 6:31Sun Earth L5 point. The satellite called
- 6:34Shihi 2 is scheduled to launch between
- 6:372028 and 2029 and it will provide a
- 6:40unique perspective on solar activity
- 6:42that we've never had before. For our
- 6:45listeners who might not be familiar, the
- 6:47L5 point or Lrangee.5 is one of five
- 6:51special locations in space where the
- 6:53gravitational forces of the Earth and
- 6:55Sun balance out. It's about 150 million
- 6:59km from Earth and spacecraft positioned
- 7:01there require minimal fuel to maintain
- 7:04their orbit because they're in a stable
- 7:06gravitational equilibrium.
- 7:08>> Exactly, Anna. and L5 provides a direct
- 7:11unobstructed view of the sun without
- 7:13Earth's atmosphere getting in the way.
- 7:15This makes it ideal for capturing
- 7:17detailed data on solar magnetic fields,
- 7:20flares, and eruptions. GI2 will be the
- 7:23first artificial probe ever stationed at
- 7:25this location. The mission has some
- 7:28impressive capabilities. GI2 is equipped
- 7:31with cuttingedge technology designed for
- 7:33high precision magnetic field detection.
- 7:36This will help reveal the intricate
- 7:38dynamics of solar eruptions. But here's
- 7:40what's really exciting. The mission aims
- 7:43to predict solar activity up to 5 days
- 7:46in advance. That's a gamecher for space
- 7:49weather forecasting. Solar flares and
- 7:51coronal mass ejections can have profound
- 7:53effects on Earth's magnetic field and
- 7:56satellite systems. We've seen how
- 7:58geomagnetic storms can disrupt
- 8:00communication networks, GPS systems, and
- 8:02even power grids. Having 5 days advanced
- 8:05warning could help protect critical
- 8:07infrastructure.
- 8:08>> It's worth noting this builds on China's
- 8:11previous solar mission. In 2021, China
- 8:14launched Shihei, their first solar
- 8:16exploration satellite, which captured
- 8:19solar Halpha spectral imaging from low
- 8:21Earth orbit. Shihi 2 represents a much
- 8:25more ambitious leap heading to a distant
- 8:27and challenging location. The mission is
- 8:30a collaborative effort between Nanjing
- 8:32University, the China Meteorological
- 8:35Administration, and the Shanghai Academy
- 8:37of Space Flight Technology. It really
- 8:40demonstrates China's growing leadership
- 8:42in space exploration and their
- 8:44commitment to understanding space
- 8:46weather. And as we become increasingly
- 8:49reliant on space-based technologies,
- 8:52understanding and predicting solar
- 8:54activity becomes more crucial than ever.
- 8:57This mission could significantly improve
- 8:59our ability to protect satellites,
- 9:01astronauts, and infrastructure on Earth.
- 9:04Now, let's turn to a mystery that had
- 9:06astronomers scratching their heads.
- 9:08>> Here's a stellar detective story for
- 9:10you. Astronomers thought they were
- 9:12watching a massive star called WG64
- 9:17undergo its death throws, possibly even
- 9:20transforming into a rare yellow hyper
- 9:22giant before going supernova. Turns out
- 9:25they were completely wrong.
- 9:27>> This is such a great example of how
- 9:29science works. Avery WHG64
- 9:33is located in the large melanic cloud
- 9:36and is one of the most luminous dust and
- 9:38shrouded red super giants in its galaxy.
- 9:41In recent years, astronomers observed
- 9:43unusual dimming and changing spectral
- 9:46features that suggested the star was
- 9:48entering an extremely rare and unstable
- 9:51phase. In 2024, the appearance of a new
- 9:54dust cloud around the star seemed to
- 9:56confirm that something dramatic was
- 9:58happening. Many researchers thought they
- 10:01were witnessing a massive star in its
- 10:03final moments. But fresh observations
- 10:05from a team led by Dr. Jaco Vanlon at
- 10:08Kil University revealed a completely
- 10:11different story. Between November 2024
- 10:14and December 2025, the team used the
- 10:18Southern African Large Telescope to
- 10:21collect detailed optical spectra of WO
- 10:24G64.
- 10:26What they found contradicted all the
- 10:28previous assumptions. Instead of the
- 10:31temperature increase you'd expect in a
- 10:33yellow hyper giant, they found strong
- 10:36absorption bands from titanium oxide
- 10:39molecules. And here's why that matters.
- 10:42Titanium oxide molecules can't survive
- 10:45in the hotter environment of a yellow
- 10:47hyper giant. That meant wo G64 hadn't
- 10:51undergone the suspected transformation
- 10:53at all. Something else was causing all
- 10:56those puzzling observations.
- 10:58>> The answer turned out to be a companion
- 11:00star. W64
- 11:03is actually part of a binary system. A
- 11:06smaller, hotter companion star orbits
- 11:08the red super giant and periodically
- 11:10interacts with its extended atmosphere.
- 11:13As Van Lon explained, the atmosphere of
- 11:15the red super giant is being stretched
- 11:17out by the approach of the companion
- 11:19star, but it hasn't been stripped
- 11:21altogether. So nearly every major
- 11:24indicator that astronomers had
- 11:25interpreted as signs of impending
- 11:27stellar death, the fading light, the
- 11:30spectral shifts, the dust formation, was
- 11:33actually caused by this companion star.
- 11:35Some of the disrupted material even
- 11:37appears to form a disc around the hot
- 11:39companion, which contributed to those
- 11:42strange spectral emissions.
- 11:43>> Banoon described it beautifully. We're
- 11:46essentially witnessing a phoenix rising
- 11:49from the ashes. It's not that WG64
- 11:53won't eventually go supernova. It will.
- 11:56But that event isn't imminent, despite
- 11:58what all the evidence seemed to suggest.
- 12:01This discovery highlights how binary
- 12:03interactions can perfectly mimic the
- 12:06hallmarks of a dying star. It's a
- 12:08humbling reminder that the universe
- 12:10still has plenty of surprises for us.
- 12:12Careful follow-up observations with
- 12:14attention to dust obscuration revealed
- 12:17that earlier spectral signals were
- 12:19misleading. Now, let's shift from
- 12:21stellar mysteries to human achievements.
- 12:23As Time magazine celebrates an historic
- 12:26moment,
- 12:27>> as NASA's Aremis 2 mission sits poised
- 12:29on launchpad 39B at Kennedy Space
- 12:32Center, Time magazine has honored the
- 12:35crew with a special commemorative cover
- 12:37issue that draws powerful parallels to
- 12:40one of history's most pivotal space
- 12:42missions. The cover features the four
- 12:45Artemis 2 astronauts, Reed Weisman,
- 12:47Jeremy Hansen, Victor Glover, and
- 12:50Christina Ko, who are scheduled to
- 12:52launch as early as February 8th for a
- 12:5410-day lunar flyby mission. The article
- 12:57accompanying it was written by Jeffrey
- 12:59Kuger, the best-selling author known for
- 13:02Apollo 13 and the Apollo murders. What's
- 13:05particularly poignant is the comparison
- 13:07Kuger draws to Apollo 8, which orbited
- 13:10the moon in December 1968.
- 13:13That was a year of tremendous turmoil in
- 13:15the United States and around the world.
- 13:17And Apollo 8's Christmas Eve broadcast
- 13:20from lunar orbit provided a moment of
- 13:22unity and inspiration that transcended
- 13:25borders and politics.
- 13:27>> As Kuger writes in the article, "Not
- 13:29every mission touches the collective
- 13:31soul, but some do. Apollo 8, Apollo 11,
- 13:36Apollo 13. These were less American
- 13:39experiences than global dramas, global
- 13:42triumphs, global joys. And he suggests
- 13:45Artemis 2 could work similar magic
- 13:47today.
- 13:48>> The mission itself will push human
- 13:50spaceflight to new limits. Artemis 2's
- 13:53trajectory will take the crew 4,700
- 13:56m beyond the far side of the moon,
- 13:59farther than our species has ever
- 14:01traveled. That will break the old record
- 14:03of 158 miles past the moon, which was
- 14:06held by the Apollo 13 astronauts during
- 14:09that dramatic 1970 mission.
- 14:12>> NASA administrator Jared Isikman posted
- 14:14sidebyside Time magazine covers from
- 14:171968 and 2026 on social media, noting
- 14:20that 58 years after Apollo 8's historic
- 14:23trip, NASA is heading back. He
- 14:26emphasized that through the Aremis
- 14:28campaign, the agency aims to maintain
- 14:30American leadership in space, land
- 14:32astronauts on the moon, and establish a
- 14:35lunar base all before the end of 2028.
- 14:38>> What strikes me about both Apollo 8 and
- 14:41Aremis 2 is their role in opening new
- 14:44chapters. Apollo 8 proved humans could
- 14:46safely journey to the moon and return,
- 14:49paving the way for Apollo 11's landing.
- 14:52Artemis 2 is similarly demonstrating the
- 14:55capabilities that will enable Artemis 3
- 14:57to put humans back on the lunar surface.
- 15:00>> And as Kuger points out, the mission
- 15:02represents not just a technological
- 15:04achievement, but a significant edge in
- 15:07any space race with China, while also
- 15:09offering the kind of public uplift that
- 15:11spaceflight has uniquely been able to
- 15:13provide since the 1960s. It's a moment
- 15:16when four people serve as emissaries for
- 15:19the 8.3 billion of us who remain
- 15:21earthbound. With the wet dress rehearsal
- 15:24happening right now and launch
- 15:26potentially just days away, this Time
- 15:28magazine issue captures what could be
- 15:30one of 2026's most inspiring moments.
- 15:34And speaking of inspiration, we need to
- 15:36remember someone who made a profound but
- 15:38often overlooked contribution to how we
- 15:41navigate our world. We're closing
- 15:44today's show with a remembrance of Dr.
- 15:46Glattis West who passed away Saturday at
- 15:48the age of 95. West was one of the
- 15:51hidden figures whose work fundamentally
- 15:53shaped modern GPS technology. Yet her
- 15:56contributions went largely unrecognized
- 15:58until recently.
- 16:00>> Glattis West's story is one of
- 16:02extraordinary perseverance and
- 16:04achievement in the face of significant
- 16:06obstacles. She was born on October 27th,
- 16:091930 in rural Southerntherland,
- 16:11Virginia, south of Richmond. Her parents
- 16:14had a small farm and most of the
- 16:16region's population were tenant farmers
- 16:18known as sharecroppers. She initially
- 16:21expected her future would lead to farm
- 16:23work or a job at the tobacco processing
- 16:25plant where her mother worked, but she
- 16:27excelled academically, becoming
- 16:29validictorian of her high school
- 16:30graduating class. She earned a full
- 16:32scholarship to Virginia State College,
- 16:34which was a historically black
- 16:36institution, and went on to earn both
- 16:38her bachelor's and master's degrees in
- 16:40mathematics. This was during the Jim
- 16:43Crow era of racial segregation. Avery,
- 16:45after graduating in 1955, the same year
- 16:49President Eisenhower banned racial
- 16:51discrimination in federal hiring, West
- 16:53began working at what was then called
- 16:55the Naval Proving Ground in Dogrren,
- 16:57Virginia. She told NPR that there were
- 16:59three other black professionals there
- 17:01and they tried to treat the leaders with
- 17:03respect while hoping for the same
- 17:05treatment in return.
- 17:07>> West stayed at Dogrren for 42 years and
- 17:10her contributions were remarkable. In
- 17:13the 1960s, she participated in a study
- 17:16showing that Pluto's motion is regular
- 17:18compared with Neptune. But her most
- 17:21significant work came in the 1970s and
- 17:2380s when she helped develop the
- 17:25foundational mathematics for GPS.
- 17:29>> What's fascinating is the complexity of
- 17:31what she accomplished. West used
- 17:33intricate algorithms to account for
- 17:35variations in gravitational title and
- 17:38other forces that distort Earth's shape.
- 17:40She programmed the IBM 7030 computer,
- 17:43also known as stretch, to deliver
- 17:45increasingly refined calculations for an
- 17:48extremely accurate model of Earth's
- 17:50shape, specifically optimized for what
- 17:52ultimately became the GPS orbit used by
- 17:54satellite.
- 17:56>> Her work essentially created the
- 17:58mathematical framework that allows GPS
- 18:00to function accurately. Today, there are
- 18:03about 4 billion GPS users worldwide,
- 18:06according to Loheed Martin. Yet, when
- 18:09asked about using GPS herself, West told
- 18:12an NPR affiliate in 2020 that she used
- 18:15it on a minimal basis. She preferred
- 18:17maps. West's career wasn't widely
- 18:20recognized until the 2016 publication of
- 18:22Margot Lee Shudderly's book, Hidden
- 18:24Figures, and the Hollywood film based on
- 18:27it. After that, the accolades came
- 18:29quickly. She was inducted into the Air
- 18:31Force Space and Missile Pioneers Hall of
- 18:33Fame in 2018, received the Webbby
- 18:36Lifetime Achievement Award in 2021, and
- 18:38was honored with the Prince Philip Medal
- 18:40by the UK's Royal Academy of
- 18:42Engineering.
- 18:43>> She was predecessed last year by her
- 18:45husband of 57 years, Ira, whom she met
- 18:48at the Naval Proving Ground. The couple
- 18:51had three children and seven
- 18:52grandchildren. Her family announced that
- 18:55she passed peacefully alongside loved
- 18:57ones. Blattis West's story reminds us
- 19:00that some of the most important
- 19:01scientific contributions come from
- 19:03unexpected places and from people who
- 19:06had to overcome tremendous barriers.
- 19:08From a childhood in rural Virginia
- 19:10during segregation to reshaping how the
- 19:13entire world navigates. Her legacy
- 19:16touches billions of lives every single
- 19:18day. Every time someone uses GPS to find
- 19:21directions, track a delivery, or
- 19:24navigate by sea or air, they're
- 19:26benefiting from the mathematical
- 19:28foundations Glattis West helped
- 19:30establish. It's a powerful reminder that
- 19:32science is built by people from all
- 19:34backgrounds, and that we should
- 19:36celebrate those contributions while the
- 19:38pioneers are still with us.
- 19:40>> And that wraps up today's episode of
- 19:42Astronomy Daily. We've journeyed from
- 19:44SpaceX's ambitious satellite plans to
- 19:47ancient star maps, from solar
- 19:49observatories at special points in space
- 19:52to stellar mysteries solved. From
- 19:54upcoming lunar missions to the legacy of
- 19:56a GPS pioneer,
- 19:58>> it's been quite a tour through the
