- Nancy Chris Roman Space Telescope Assembly Complete: NASA has successfully assembled the Nancy Chris Roman Space Telescope, a major milestone that brings us closer to its anticipated launch in May 2027. This powerful telescope, equipped with a 288-megapixel camera, promises to gather data hundreds of times faster than Hubble, potentially unveiling over 100,000 new exoplanets and billions of galaxies.
- Russian Soyuz Rocket Launch Damage: Following a successful launch to the International Space Station, damage was discovered at the Baikonur Cosmodrome, attributed to vibrations and heat from the launch. Repairs are expected to take around three months, but there’s no immediate threat to future crewed missions.
- Satellite Mega Constellations and Light Pollution: A new forecast reveals that satellite mega constellations could severely impact astronomical observations, with projections showing that 1/3 of Hubble's images may be contaminated with satellite trails by the 2030s. Solutions are being explored to mitigate this growing issue.
- Geological Differences Between Earth and Venus: Recent research sheds light on the geological differences between Earth and Venus, highlighting that Venus operates under a 'squishy lid' regime, which affects its volcanism and tectonic activity. This new framework helps explain the presence of active volcanoes on the otherwise stagnant planet.
- James Webb Space Telescope's Stunning New Image: The James Webb Space Telescope captures a breathtaking image of two colliding dwarf galaxies, NGC 4490 and NGC 4485, revealing a bridge of gas and new stars formed from their gravitational interaction, showcasing the dynamic nature of the universe.
- Rare High-Definition Sunspot Images: Astronomers have captured rare high-definition images of sunspots just before they erupted in a powerful solar flare. These images provide critical insights into the sun's magnetic activity and could improve our ability to predict solar events that impact technology on Earth.

00:00:00 --> 00:00:03 Avery: Welcome to Astronomy Daily, the podcast that
00:00:03 --> 00:00:06 brings you the universe one story at a time.
00:00:06 --> 00:00:07 I'm Avery.
00:00:07 --> 00:00:09 Anna: And I'm Anna. It's great to have you with us
00:00:10 --> 00:00:12 today. We've got stories that range from
00:00:12 --> 00:00:14 NASA's next great observatory to a stunning
00:00:14 --> 00:00:16 new image from the James Webb Space
00:00:16 --> 00:00:19 Telescope. We'll also be looking at some
00:00:19 --> 00:00:21 trouble on a Kazakhstani launch pad and why
00:00:21 --> 00:00:23 Earth is so geologically unique.
00:00:24 --> 00:00:26 Avery: Let's not wait. Anna, why don't you start us
00:00:26 --> 00:00:27 off with our first story?
00:00:27 --> 00:00:30 It sounds like there's a new powerhouse
00:00:30 --> 00:00:31 telescope getting ready for the cosmic st.
00:00:32 --> 00:00:33 That's right, Avery.
00:00:33 --> 00:00:36 Anna: NASA has just completed the assembly of the
00:00:36 --> 00:00:38 Nancy Grace Roman Space Telescope.
00:00:38 --> 00:00:40 Technicians at, ah, the Goddard Space Flight
00:00:40 --> 00:00:43 center join the inner and outer portions of
00:00:43 --> 00:00:45 the spacecraft, which is a major milestone.
00:00:45 --> 00:00:47 Avery: So it's fully built now. When do we get to
00:00:47 --> 00:00:48 see it in action?
00:00:49 --> 00:00:51 Anna: After some final testing, it's slated to
00:00:51 --> 00:00:54 launch by May 2027. Although the team
00:00:54 --> 00:00:56 says they're on track for a potential launch
00:00:56 --> 00:00:59 as early as fall 2026. A
00:00:59 --> 00:01:01 SpaceX Falcon Heavy will carry it to its
00:01:01 --> 00:01:03 destination. A million miles.
00:01:04 --> 00:01:06 Avery: A million miles. Same neighborhood as the
00:01:06 --> 00:01:08 Webb Telescope. Then what's the mission for
00:01:08 --> 00:01:11 Roman? What mysteries is it designed to
00:01:11 --> 00:01:11 solve?
00:01:12 --> 00:01:14 Anna: Its scope is just immense. The primary
00:01:14 --> 00:01:17 Instrument is a 288 megapixel
00:01:17 --> 00:01:20 wide field camera. To put that in
00:01:20 --> 00:01:22 perspective, Roman is expected to gather data
00:01:22 --> 00:01:25 hundreds of times faster than the Hubble
00:01:25 --> 00:01:26 Space Telescope.
00:01:26 --> 00:01:28 Avery: Wow. Hundreds of times faster.
00:01:28 --> 00:01:31 Anna: Exactly. In its first five years alone, the
00:01:31 --> 00:01:33 mission is projected to unveil more than
00:01:33 --> 00:01:36 100 new exoplane, hundreds of
00:01:36 --> 00:01:39 millions of stars, and billions of galaxies.
00:01:39 --> 00:01:42 It's also testing a new technology called a
00:01:42 --> 00:01:44 coronagraph instrument. This is designed to
00:01:44 --> 00:01:46 block out the overwhelming light from a star,
00:01:46 --> 00:01:49 allowing astronomers to directly image the
00:01:49 --> 00:01:52 much fainter planets orbiting it. It's a huge
00:01:52 --> 00:01:54 leap forward in our ability to survey the
00:01:54 --> 00:01:54 cosmos.
00:01:55 --> 00:01:57 Avery: That's incredible. From one powerful machine
00:01:57 --> 00:01:58 to another.
00:01:58 --> 00:02:00 Our next story is a bit more down to Earth,
00:02:00 --> 00:02:03 and unfortunately it involves some damage.
00:02:04 --> 00:02:06 Anna: Damage is the polite way of putting it.
00:02:06 --> 00:02:08 Though it's not as catastrophic as some would
00:02:08 --> 00:02:08 have you believe.
00:02:09 --> 00:02:12 Avery: On November 27, a Russian
00:02:12 --> 00:02:14 Soyuz rocket successfully launched three
00:02:14 --> 00:02:16 astronauts to the International Space Station
00:02:16 --> 00:02:19 from the Baikonur Cosmodrome. The launch
00:02:19 --> 00:02:21 itself went off without a hitch.
00:02:21 --> 00:02:24 Anna: Okay, so what's the problem?
00:02:24 --> 00:02:27 Avery: The issue was discovered during routine
00:02:27 --> 00:02:30 post launch inspections. Officials from
00:02:30 --> 00:02:33 Roscosmos, Russia space agency
00:02:33 --> 00:02:36 reported finding damage to several launch
00:02:36 --> 00:02:37 pad components.
00:02:38 --> 00:02:40 Anna: That doesn't sound good. Do they know what
00:02:40 --> 00:02:43 caused it? Roscosmos is still assessing the
00:02:43 --> 00:02:45 situation, but they've said all the necessary
00:02:45 --> 00:02:47 spare parts are available for a quick repair.
00:02:48 --> 00:02:50 However, one expert, Brian Harvey, has
00:02:50 --> 00:02:53 suggested a possible cause. He believes a
00:02:53 --> 00:02:56 combination of the intense vibration and heat
00:02:56 --> 00:02:58 from the launch, along with some improperly
00:02:58 --> 00:03:00 installed roller pins, may have caused a
00:03:00 --> 00:03:03 service tower to topple over after the rocket
00:03:03 --> 00:03:06 had cleared the pad. Right. A service tower
00:03:06 --> 00:03:08 falling over would certainly count as damage.
00:03:09 --> 00:03:11 What does this mean for future launches?
00:03:11 --> 00:03:13 Avery: Harvey, uh, estimates it could take about
00:03:13 --> 00:03:16 three months to repair, likely scavenging
00:03:16 --> 00:03:18 parts from other launch pads. The good news
00:03:18 --> 00:03:21 is that the next crew handover at the ISS
00:03:21 --> 00:03:23 isn't scheduled until July, and the next
00:03:23 --> 00:03:26 astronaut mission from US soil is a
00:03:26 --> 00:03:29 SpaceX flight in February, so no
00:03:29 --> 00:03:31 astronauts are stranded. However, the next
00:03:31 --> 00:03:34 Russian Progress supply ship delivery to the
00:03:34 --> 00:03:37 spaceship will be delayed. We'll be keeping
00:03:37 --> 00:03:39 an eye on how quickly those repairs progress,
00:03:39 --> 00:03:42 but please note, there is no panic. And it
00:03:42 --> 00:03:44 isn't the end of the Russian space program.
00:03:44 --> 00:03:46 As has been reported in some of the more
00:03:46 --> 00:03:49 sensationalist media, it will be repaired
00:03:49 --> 00:03:50 and back in business.
00:03:51 --> 00:03:54 Anna: From problems on the ground to problems
00:03:54 --> 00:03:56 in orbit. Avery, we often talk about light
00:03:56 --> 00:03:59 pollution for ground based telescopes, but a,
00:03:59 --> 00:04:02 uh, new forecast reveals that even our eyes
00:04:02 --> 00:04:04 in space are not safe.
00:04:04 --> 00:04:06 Avery: You're talking about satellite mega
00:04:06 --> 00:04:08 constellations, right? I've seen some
00:04:08 --> 00:04:11 startling images of bright streaks ruining
00:04:11 --> 00:04:13 astronomical photos.
00:04:13 --> 00:04:16 Anna: Exactly, and it's getting worse. If the
00:04:16 --> 00:04:19 current industry proposals for about half a
00:04:19 --> 00:04:22 million new satellites become a reality,
00:04:22 --> 00:04:24 the problem will escalate dramatically.
00:04:24 --> 00:04:27 Projections show that by the2030s,
00:04:27 --> 00:04:30 1/3 of all images from the Hubble
00:04:30 --> 00:04:33 Space Telescope will be contamina with
00:04:33 --> 00:04:34 satellite trails.
00:04:34 --> 00:04:37 Avery: One third? That's a massive loss of data
00:04:37 --> 00:04:39 and time. For one of our most important
00:04:40 --> 00:04:42 scientific instruments, it is.
00:04:42 --> 00:04:45 Anna: And for some newer telescopes, it's even
00:04:45 --> 00:04:48 more dire. The Chinese space station
00:04:48 --> 00:04:50 telescope Sentient is projected to be
00:04:50 --> 00:04:53 the worst affected. Some studies predict
00:04:53 --> 00:04:56 contamination and more than 96%
00:04:56 --> 00:04:59 of its observations. With an average of
00:04:59 --> 00:05:02 92 satellite trails per exposure.
00:05:03 --> 00:05:06 Avery: 96%. At that point, the
00:05:06 --> 00:05:08 telescope is almost unusable for its intended
00:05:08 --> 00:05:11 purpose, it seems unsustainable.
00:05:12 --> 00:05:14 Are there any solutions being discussed?
00:05:14 --> 00:05:17 Anna: There are. Mitigation strategies are
00:05:17 --> 00:05:19 actively being developed. They include better
00:05:19 --> 00:05:22 orbital tracking to help astronomers avoid
00:05:22 --> 00:05:24 pointing at satellites, international
00:05:24 --> 00:05:26 coordination on satellite brightness
00:05:26 --> 00:05:29 standards, and perhaps most importantly,
00:05:29 --> 00:05:31 restricting the altitudes of these large
00:05:31 --> 00:05:33 constellations to below
00:05:34 --> 00:05:36 kilometers, which would reduce their
00:05:36 --> 00:05:39 visibility. It's a critical issue for the
00:05:39 --> 00:05:40 future of astronomy.
00:05:40 --> 00:05:43 Avery: It's a stark reminder of how crowded our
00:05:43 --> 00:05:44 orbital space is becoming.
00:05:45 --> 00:05:48 Okay, from our near space environment to our
00:05:48 --> 00:05:51 planetary neighbors, let's talk about Venus.
00:05:51 --> 00:05:54 We often call it Earth's twin. But new
00:05:54 --> 00:05:56 research is helping us understand one of the
00:05:56 --> 00:05:59 biggest differences between them. Plate
00:05:59 --> 00:05:59 tectonics.
00:05:59 --> 00:06:02 Anna: Plate. Right. Earth has this
00:06:02 --> 00:06:04 active moving crust, while Venus is often
00:06:04 --> 00:06:07 described as having a, uh, stagnant single
00:06:07 --> 00:06:09 plate surface. Why is that?
00:06:10 --> 00:06:12 Avery: An international team has developed a new
00:06:12 --> 00:06:15 framework for understanding how planets work
00:06:15 --> 00:06:17 geologically. Using numerical
00:06:17 --> 00:06:19 models, they identified six
00:06:20 --> 00:06:22 distinct regimes for planetary
00:06:22 --> 00:06:25 tectonics. Earth exists in what they
00:06:25 --> 00:06:28 call the mobile lid regime, which is
00:06:28 --> 00:06:30 crucial for our planet's long term
00:06:30 --> 00:06:33 habitability as it regulates climate by
00:06:33 --> 00:06:34 cycling carbon.
00:06:34 --> 00:06:37 Anna: The mobile lid. I like that. So
00:06:37 --> 00:06:39 what kind of lid does Venus have?
00:06:40 --> 00:06:42 Avery: The studies suggest Venus operates under
00:06:42 --> 00:06:45 what's called a plutonic squishy lid
00:06:45 --> 00:06:48 or an episodic squishy lid regime.
00:06:48 --> 00:06:51 In this model, the lithosphere, the planet's
00:06:51 --> 00:06:54 outer shell, is too hot and weak to
00:06:54 --> 00:06:56 break into distinct plates like Earth's.
00:06:57 --> 00:06:59 Instead, rising magma from the mantle
00:06:59 --> 00:07:01 weakens the crust from below.
00:07:02 --> 00:07:04 Anna: A squishy lid. So it doesn't move
00:07:04 --> 00:07:07 globally, but it's not totally inactive
00:07:07 --> 00:07:07 either.
00:07:08 --> 00:07:11 Avery: Precisely. This leads to regional
00:07:11 --> 00:07:14 intermittent volcanism rather than the global
00:07:14 --> 00:07:17 tectonics we see here. And this model
00:07:17 --> 00:07:19 actually helps explain some other recent
00:07:19 --> 00:07:21 discoveries. We've seen findings suggesting
00:07:21 --> 00:07:24 there are active volcanoes on Venus, which
00:07:24 --> 00:07:27 seemed puzzling without plate tectonics.
00:07:27 --> 00:07:30 This squishy lid idea provides a mechanism
00:07:30 --> 00:07:32 for that volcanism to occur.
00:07:33 --> 00:07:36 Anna: Speaking of spectacular space phenomena,
00:07:36 --> 00:07:38 let's turn back to the James Webb Space
00:07:38 --> 00:07:40 Telescope. It has captured another
00:07:40 --> 00:07:43 breathtaking image, this time of a close
00:07:43 --> 00:07:46 encounter between two dwarf galaxies.
00:07:46 --> 00:07:49 Avery: Oh, I saw this one. The image is just
00:07:49 --> 00:07:52 stunning. It's the pair NGC
00:07:52 --> 00:07:54 4490 and NGC
00:07:54 --> 00:07:56 4485. Right.
00:07:56 --> 00:07:59 Anna: That's them. They're about 24 million
00:07:59 --> 00:08:01 light years away, and they're in the process
00:08:01 --> 00:08:03 of colliding. The Webb image
00:08:04 --> 00:08:07 detailed it reveals a glowing bridge of gas
00:08:07 --> 00:08:10 and streams of newborn stars
00:08:10 --> 00:08:12 connecting the two galaxies. The
00:08:12 --> 00:08:14 gravitational interaction between them has
00:08:14 --> 00:08:16 spurred a massive burst of new star
00:08:16 --> 00:08:17 formation.
00:08:18 --> 00:08:20 Avery: So they're creating new stars as, ah, they
00:08:20 --> 00:08:23 pull each other apart. That's poetic.
00:08:23 --> 00:08:26 Can we tell how this interaction unfolded?
00:08:26 --> 00:08:28 Anna: We can. By analyzing the different
00:08:28 --> 00:08:31 populations of stars, researchers have been
00:08:31 --> 00:08:34 able to trace the timeline to. They suggest
00:08:34 --> 00:08:37 the two galaxies first swept past each
00:08:37 --> 00:08:39 other about 200 million years ago.
00:08:40 --> 00:08:43 During that pass, the larger galaxy,
00:08:43 --> 00:08:45 NGC4490
00:08:45 --> 00:08:48 began siphoning gas from its smaller
00:08:48 --> 00:08:50 partner, NGC4485.
00:08:51 --> 00:08:54 That stolen gas is now fueling the starburst
00:08:54 --> 00:08:56 we see in that glowing bridge.
00:08:57 --> 00:08:59 Avery: Incredible. It's like cosmic
00:08:59 --> 00:09:02 archaeology. A fantastic image with a
00:09:02 --> 00:09:04 fascinating story behind it.
00:09:05 --> 00:09:07 Now for our final story, we're coming
00:09:07 --> 00:09:10 much closer to home, to our very
00:09:10 --> 00:09:13 own star. In early November,
00:09:13 --> 00:09:16 astronomers captured some extremely rare
00:09:16 --> 00:09:18 high definition images of sunspots in
00:09:18 --> 00:09:21 an active region designated NOAA
00:09:21 --> 00:09:23 14.
00:09:24 --> 00:09:26 Anna: And what makes these images so special?
00:09:27 --> 00:09:29 Avery: The timing. The images were taken by
00:09:29 --> 00:09:32 the Gregor solar telescope in Spain
00:09:32 --> 00:09:35 just 30 minutes before those same sunspots
00:09:35 --> 00:09:38 erupted, emitting a powerful
00:09:38 --> 00:09:40 X1.2 class solar flare.
00:09:41 --> 00:09:44 Anna: Wow. That's like having a camera pointed at a
00:09:44 --> 00:09:47 volcano right before it blows. Capturing
00:09:47 --> 00:09:49 that with a ground based telescope must be
00:09:49 --> 00:09:51 incredibly difficult.
00:09:51 --> 00:09:54 Avery: It is. You have to be looking at the
00:09:54 --> 00:09:57 right spot at the right time, and you need
00:09:57 --> 00:09:59 clear weather. It's a rare trifecta.
00:10:00 --> 00:10:03 The images are remarkable. They show what
00:10:03 --> 00:10:05 are called penumbral fibrils. These are
00:10:05 --> 00:10:08 the filaments extending from the dark center
00:10:08 --> 00:10:11 of the sunspot that are strongly curved and
00:10:11 --> 00:10:12 braided together.
00:10:13 --> 00:10:15 Anna: And what does that braiding tell us?
00:10:16 --> 00:10:18 Avery: It's a clear visual indicator of a highly
00:10:18 --> 00:10:21 stressed and tangled magnetic field. Think
00:10:21 --> 00:10:24 of it like a tightly wound rubber band.
00:10:25 --> 00:10:27 That immense stored energy is a direct
00:10:27 --> 00:10:30 precursor to an explosive release, which
00:10:30 --> 00:10:32 is exactly what happened 30 minutes later
00:10:32 --> 00:10:35 with the solar flare. And this is just the
00:10:35 --> 00:10:37 beginning. Researchers are currently
00:10:37 --> 00:10:40 processing nearly 40 more data sets from
00:10:40 --> 00:10:42 the telescope, which could revolutionize how
00:10:42 --> 00:10:45 we predict these powerful solar events.
00:10:46 --> 00:10:49 Anna: And better prediction is crucial.
00:10:49 --> 00:10:52 These powerful solar events can disrupt
00:10:52 --> 00:10:55 satellites, power grids, and even pose a
00:10:55 --> 00:10:57 risk to astronauts. Understanding their
00:10:57 --> 00:11:00 warning signs is vital for our technological
00:11:00 --> 00:11:03 infrastructure. And that brings us to
00:11:03 --> 00:11:06 the end of our news roundup for today. It's
00:11:06 --> 00:11:08 been another busy day in the cosmos.
00:11:08 --> 00:11:11 Avery: It certainly has. Thanks for joining us on
00:11:11 --> 00:11:13 Astronomy Daily. We'll be back again tomorrow
00:11:13 --> 00:11:16 with another look at the latest news from
00:11:16 --> 00:11:18 across the universe. Until then, I'm Avery
00:11:19 --> 00:11:20 and I'm Anna.
00:11:20 --> 00:11:22 Anna: Reminding you to keep looking up
00:11:22 --> 00:11:23 Astronomy Day.
00:11:24 --> 00:11:26 Avery: The stories we told.
00:11:32 --> 00:11:34 The stories the to.
