Transcript
- 0:00Welcome to Astronomy Daily, your source
- 0:03for the latest space and astronomy news.
- 0:05I'm Anna.
- 0:06>> And I'm Avery. Today's Tuesday, January
- 0:0927th, 2026, and we've got some
- 0:12fascinating stories lined up for you.
- 0:14>> We certainly do. On today's episode,
- 0:17we're diving into NASA's groundbreaking
- 0:19new dark matter map, getting the latest
- 0:22updates on this week's orbital launch
- 0:24schedule, and learning about what the
- 0:26Aremis 2 crew might see on the far side
- 0:29of the moon.
- 0:30>> Plus, we'll explore stunning new
- 0:32insights into Jupiter's complex cloud
- 0:34systems. Find out about a rare solar
- 0:37eclipse that only a handful of people
- 0:39will witness, and get the latest on
- 0:41SpaceX's upgraded Starship development.
- 0:44>> Let's get started. Take it away, Anna.
- 0:46>> Our top story today comes from NASA's
- 0:49Jet Propulsion Laboratory, where
- 0:51scientists have created one of the most
- 0:53detailed dark matter maps ever produced
- 0:56using data from the James Web Space
- 0:58Telescope.
- 0:59>> This is really exciting stuff, Anna. The
- 1:02map shows how dark matter, that
- 1:04invisible ghostly material that makes up
- 1:07most of the universe's mass, overlaps
- 1:09and intertwines with regular matter,
- 1:12like stars and galaxies. Published
- 1:14Monday in Nature Astronomy, this map is
- 1:17twice as sharp as any previous dark
- 1:19matter map made by other observatories.
- 1:22Diana Skoggnia, the lead author and
- 1:25astrophysicist at JPL, described it as
- 1:28seeing the invisible scaffolding of the
- 1:30universe in stunning detail for the
- 1:32first time.
- 1:34>> What's particularly fascinating is how
- 1:36the map confirms that dark matter and
- 1:38regular matter have essentially grown up
- 1:41together. Wherever you see a massive
- 1:43cluster of thousands of galaxies,
- 1:45there's an equally massive amount of
- 1:47dark matter in the same place. When you
- 1:50see strings of regular matter connecting
- 1:52clusters, dark matter strings are there,
- 1:54too. The team used Web's unprecedented
- 1:58sensitivity to observe nearly 800,000
- 2:01galaxies in a region of sky about 2.5
- 2:04times larger than the full moon. They
- 2:07detected dark matter by observing how
- 2:09its mass curves space itself, which
- 2:12bends light from distant galaxies as it
- 2:15travels to Earth.
- 2:16>> Here's something to ponder. Without dark
- 2:18matter, we might not even be here. Dark
- 2:21matter began clumping together first in
- 2:24the early universe, and those clumps
- 2:26then pulled regular matter together,
- 2:28creating the conditions for stars and
- 2:30galaxies to form earlier than they would
- 2:33have otherwise. That earlier star
- 2:35formation was crucial because those
- 2:37first generations of stars turned
- 2:39hydrogen and helium into the rich array
- 2:42of elements that now make up planets
- 2:44like Earth. So in a very real sense,
- 2:47dark matter influenced the creation of
- 2:49the elements necessary for life. Looking
- 2:52ahead, the upcoming Nancy Grace Roman
- 2:55Space Telescope will map dark matter
- 2:58over an area 4,400 times bigger than
- 3:01this web study. Though it won't match
- 3:03web's incredible resolution. For even
- 3:06more detailed looks, we'll have to wait
- 3:08for next generation telescopes like the
- 3:10proposed Habitable Worlds Observatory.
- 3:13>> Fascinating research that's literally
- 3:15revealing the invisible foundation of
- 3:17our universe.
- 3:19>> Moving on to this week's launch
- 3:20schedule. It's shaping up to be a busy
- 3:23last week of January with flights from
- 3:25Florida, California, and New Zealand on
- 3:27the manifest.
- 3:28>> That's right. SpaceX is planning to
- 3:31close out the month with the GPS 3SV09
- 3:35mission along with up to three Starlink
- 3:37launches. The GPS launch is scheduled
- 3:40for late Monday evening from Cape
- 3:42Canaveral. The GPS 3SV09
- 3:45satellite named Ellison Onuka after one
- 3:48of the fallen Challenger astronauts will
- 3:51be launched to medium Earth orbit. This
- 3:53spacecraft offers improved accuracy and
- 3:56jamming resistance over previous
- 3:58versions of GPS.
- 3:59>> Meanwhile, Rocket Labs Electron is
- 4:02preparing for the Bridging the Swarm
- 4:03mission from New Zealand's Mahia
- 4:05Peninsula on Wednesday. This launch will
- 4:08carry South Korea's Neon Sat 1A
- 4:11observation satellite to sunsyn
- 4:13synchronous orbit.
- 4:14>> The Neon Sat constellation is designed
- 4:16to provide near real-time disaster
- 4:18monitoring capability for the Korean
- 4:20Peninsula. The 100 kg Neon SAT 1A
- 4:24features a highresolution optical camera
- 4:26and will join an existing Neonat
- 4:29satellite already in orbit.
- 4:30>> This mission has already faced a couple
- 4:32of delays. It was originally scheduled
- 4:34to launch back in December, but was
- 4:36scrubbed after sensor issues during
- 4:38Countdown.
- 4:39>> SpaceX also has multiple Starlink
- 4:41missions on the schedule this week from
- 4:43both coasts. Group 17-9 from Vandenberg
- 4:47Space Force Base in California on
- 4:49Thursday and Group 6-101 from Cape
- 4:53Canaveral later that same day. And
- 4:55looking ahead to early February, the
- 4:57first Starlink mission of next month,
- 4:59Group 6-103,
- 5:01is currently scheduled for Sunday,
- 5:03February 1st.
- 5:04>> China also has two possible flights on
- 5:07the manifest. A Changang 7A from Heinen
- 5:10Island and a Gilong 3 from the South
- 5:13China Sea, though neither has a
- 5:15confirmed launch date yet. It's worth
- 5:17noting that China's year in space flight
- 5:19has already been eventful with two
- 5:21launch failures within 12 hours in mid
- 5:23January. So, they may be proceeding
- 5:26cautiously with these upcoming missions.
- 5:28Okay, moving on. Our next story takes us
- 5:31to preparations for NASA's Aremis 2
- 5:33mission where four astronauts are
- 5:35training to become the first humans to
- 5:38see parts of the moon that have remained
- 5:40hidden from view even during the Apollo
- 5:42missions. The Aremis 2 crew, Reed
- 5:45Weissman, Victor Glover, Christina
- 5:47Hammock Coach, and Jeremy Hansen won't
- 5:50land on the lunar surface, but they'll
- 5:52fly around the far side of the moon and
- 5:54potentially observe regions never before
- 5:57seen by human eyes.
- 5:58>> Among the most significant targets is
- 6:00Mari oriental, a vast 600-m wide impact
- 6:04basing that sits along the edge of the
- 6:07lunar far side. Its location makes it
- 6:09nearly impossible to view from Earth
- 6:12despite its massive scale.
- 6:14>> The crew will spend a dedicated
- 6:15three-hour segment of their mission
- 6:17focusing on direct lunar observation.
- 6:20NASA exploration scientist Jacob Leecher
- 6:22emphasizes that human vision can detect
- 6:25subtle surface differences, variations
- 6:27in brightness or texture that indicate
- 6:30differences in rock composition and
- 6:32geological age. What's fascinating is
- 6:34that the astronauts have been training
- 6:36extensively in geology, including
- 6:38simulated exercises in Iceland, where
- 6:41they practiced identifying volcanic and
- 6:43impact related features in environments
- 6:46resembling the moon. The far side of the
- 6:48moon holds a geological record less
- 6:50disturbed than the near side. While much
- 6:52of the near side is covered with maria,
- 6:55vast plains of ancient lava that have
- 6:57erased older surface features, the far
- 6:59side remains heavily cratered and
- 7:01relatively intact.
- 7:03>> Because of tidal locking, the moon
- 7:05always shows the same face to Earth.
- 7:08Until the Soviet Luna 3 mission in 1959,
- 7:11no one had any idea what the far side
- 7:14looked like. Even the Apollo missions
- 7:16only had brief views and poor lighting.
- 7:18Artemis 2 breaks that pattern by taking
- 7:21advantage of a launch window and flight
- 7:23path that ensures better visibility of
- 7:25the hidden hemisphere. The mission is
- 7:27currently scheduled for no earlier than
- 7:29February 6th. And astronaut Christina
- 7:32noted that the mission may help
- 7:34shift public understanding away from the
- 7:36outdated phrase the dark side of the
- 7:39moon which falsely implies the region
- 7:41lacks sunlight. An exciting mission that
- 7:44will give us unprecedented views of
- 7:46lunar territory that remained largely
- 7:48mysterious for all of human history.
- 7:50>> Now, let's turn our attention to
- 7:51Jupiter, where NASA's Juno spacecraft
- 7:54continues to reveal the gas giant
- 7:56secrets from beneath its dense cloud
- 7:59layers.
- 7:59>> Juno has been orbiting Jupiter since
- 8:022016, peering through storms and
- 8:04cyclones to unveil the planet's hidden
- 8:06complexity. And recent observations are
- 8:09showing just how much more intricate
- 8:11Jupiter is than we ever imagined.
- 8:13>> One of the most fundamental questions
- 8:16scientists have debated for decades is
- 8:18how deep Jupiter's distinctive cloud
- 8:21bands actually go. By measuring
- 8:23Jupiter's gravity field, Juno discovered
- 8:26that these belts and zones, which are
- 8:29alternating east and west flowing jet
- 8:31streams, extend about 1,900 m or 3,000
- 8:36km below the cloud tops. That's
- 8:39incredible depth. And Juno's discoveries
- 8:42have completely upended our
- 8:43understanding of Jupiter's interior
- 8:45structure, too. Scientists long thought
- 8:48Jupiter had a small solid core
- 8:50surrounded by hydrogen and helium, but
- 8:53Juno's data suggests the planet has a
- 8:55larger, more diluted core than
- 8:57previously believed. The spacecraft has
- 9:00also provided the first detailed views
- 9:02of Jupiter's north pole, revealing
- 9:05massive cyclonic storms arranged in
- 9:07fascinating patterns. Eight storms in an
- 9:10octagonal pattern in the north and five
- 9:13in a pentagonal pattern in the south.
- 9:15These storms are extremely resilient and
- 9:18have persisted for years. And here's
- 9:21something really intriguing. Juno
- 9:23recently captured images showing a
- 9:25mysterious green glow near Jupiter's
- 9:27north pole. The flash of light was
- 9:29traveling at breakneck speed, which
- 9:32makes capturing it even more remarkable.
- 9:34>> Scientists believe this could be
- 9:36lightning, but Jupiter's lightning is
- 9:39vastly different from Earth's. It's
- 9:41caused by clouds containing ammonia
- 9:43water solution and can be much more
- 9:46powerful than terrestrial lightning.
- 9:48>> Juno's mission has been extended
- 9:50multiple times and was scheduled to end
- 9:52in September 2025, but appears to be
- 9:56still be operational with no new end
- 9:58date being promoted. During this
- 10:00extended phase, the spacecraft is
- 10:03conducting close flybys of Jupiter's
- 10:05intriguing Galilean moons, Ganyde,
- 10:08Europa, and Io.
- 10:10>> Eventually, Juno will meet its end by
- 10:13burning up in Jupiter's atmosphere. But
- 10:15until then, it continues to
- 10:17revolutionize our understanding of the
- 10:19solar system's largest planet. Our next
- 10:22story involves a celestial event that
- 10:24very few people will witness. A rare
- 10:27annular solar eclipse set to occur over
- 10:30one of the most remote places on Earth.
- 10:33On February 17th, 2026, a spectacular
- 10:37ring of fire eclipse will be visible
- 10:39from a narrow stretch of Antarctica. The
- 10:42phenomenon will only be fully visible
- 10:44from an uninhabited region of the
- 10:46continent with just two research
- 10:48stations falling within the events path.
- 10:51The antumbal shadow of the moon, the
- 10:54area where the full annular eclipse can
- 10:56be seen, will travel across a 2661-m
- 11:01stretch of mainland Antarctica. Only two
- 11:03inhabited locations fall within this
- 11:06narrow band. Concordia station, a French
- 11:09Italian base, and Mney station operated
- 11:12by Russia.
- 11:13>> At Concordia, annularity will last 2
- 11:16minutes and 1 second with the sun
- 11:18positioned 5° above the horizon. At
- 11:21Miernney, it will experience 1 minute
- 11:24and 52 seconds of annularity with the
- 11:26sun slightly higher at 10°. Given the
- 11:30extreme location and limited
- 11:32infrastructure, eclipse meteorologist
- 11:34Jay Anderson noted that it's a challenge
- 11:37to reach and neither of the two
- 11:39inhabited locations is set up to welcome
- 11:41tourists.
- 11:42>> However, a partial eclipse will be
- 11:44visible over a much larger region,
- 11:47including several Antarctic research
- 11:49bases, parts of southeastern Africa, the
- 11:52southern tip of South America, and
- 11:54stretches of the Pacific, Atlantic, and
- 11:56Indian oceans. For example, Poland's AB
- 12:00Dabberlonsky station will see 92% of the
- 12:03sun covered while McMmetoro station in
- 12:06the US will see 86%.
- 12:09Even distant cities like Durban in South
- 12:11Africa will witness about 16% coverage.
- 12:14Weather could be a significant factor
- 12:16though. Mierney station averages 65%
- 12:20cloud cover in February, while Concordia
- 12:22has a clearer profile with about 35%
- 12:25coverage. and temperatures can drop as
- 12:28low as minus 112°
- 12:31F.
- 12:32>> Interestingly, the eclipse itself might
- 12:35improve viewing conditions. The sudden
- 12:37temperature drop from the eclipse can
- 12:39disrupt local cloud formation,
- 12:41potentially causing convective clouds to
- 12:43dissipate. Though, if you're one of the
- 12:46handful of researchers stationed in
- 12:48Antarctica next month, you might be in
- 12:50for a spectacular show, assuming the
- 12:53clouds cooperate and you can brave the
- 12:55extreme cold. And finally, in some late
- 12:58breaking news, we have an update on
- 13:00SpaceX's Starship development program.
- 13:04According to a post from CEO Elon Musk,
- 13:06the delayed first test of SpaceX's
- 13:08upgraded Starship rocket version 3 is
- 13:12now slated for mid-March. This third
- 13:15version of Starship is larger and more
- 13:17powerful than previous iterations.
- 13:19Crucially, SpaceX plans to use Starship
- 13:22V3 to launch its next generation
- 13:25Starlink satellites, which will be
- 13:27capable of faster data speeds, but are
- 13:30heavier and larger. It's also the first
- 13:32version designed to dock with other
- 13:34Starships in Earth orbit, a capability
- 13:37the company needs to reach the moon or
- 13:39Mars. This comes as SpaceX faces
- 13:41pressure from the Trump administration
- 13:43to return US astronauts to the lunar
- 13:45surface before the end of its second
- 13:47term. SpaceX was making progress toward
- 13:50a launch of Starship V3 in late 2025,
- 13:54but in November, the booster stage
- 13:56suffered a major explosion during
- 13:58testing that blew out an entire side of
- 14:01the steel rocket. The company said it
- 14:03was performing gas system pressure
- 14:05testing when the explosion happened, but
- 14:07hasn't offered a more detailed breakdown
- 14:09of what went wrong. The second version
- 14:12of Starship was a mixed bag. The program
- 14:15successfully reached orbit, deployed
- 14:17dummy versions of next generation
- 14:19Starling satellites and caught multiple
- 14:21booster stages after they returned to
- 14:24the launchpad. But Starship V2 also
- 14:27suffered several explosions and
- 14:29setbacks. Some resulted from SpaceX's
- 14:31developmental approach of pushing test
- 14:33vehicles to or past their limits. Others
- 14:36were more unexpected, like when a
- 14:38Starship vehicle erupted in a massive
- 14:40fireball during ground testing last
- 14:42June.
- 14:43>> Meanwhile, competition is emerging. Jeff
- 14:46Bezos's New Glenn rocket successfully
- 14:49launched for the first time in January
- 14:512025 and completed its first booster
- 14:54landing in November. Blue Origin is
- 14:57planning a third New Glenn launch in
- 14:59late February.
- 15:00>> And late last year, Blue Origin revealed
- 15:03it's developing a larger Superheavy
- 15:05variant of New Glenn, which more
- 15:07directly competes with Starship.
- 15:09>> So, while SpaceX continues to dominate
- 15:12the global launch market, other players
- 15:14are starting to close the gap. It'll be
- 15:17interesting to see how the Starship V3
- 15:19test goes in March.
- 15:21>> And that wraps up today's episode of
