  • Comet C/2025 A6 LEMMON Shines Bright: This October, Comet C/2025 A6 LEMMON makes a stunning encore appearance alongside Comet R2 Swan, offering a spectacular view for observers. Currently brightening, A6 LEMMON is set to reach perihelion on November 8th, providing an excellent opportunity for binocular enthusiasts to catch a glimpse of this celestial wanderer.
  • Interstellar Comet 3I Atlas: The fascinating interstellar comet 3I Atlas is also on the radar, known for its unusual backward-looking tail due to internal activity. With an estimated age of 3 to 14 billion years, it offers a glimpse into the early universe's history as it approaches perihelion on October 29th and passes near Venus in early November.
  • Warm Early Universe Discovery: New research reveals that the early universe was unexpectedly warmer than previously thought, particularly during the epoch of reionization. This finding, based on a decade of data analysis, reshapes our understanding of the conditions that allowed the first stars and galaxies to form.
  • Solar Rain Uncovered: Scientists have solved the mystery of solar rain, discovering that cooler, denser plasma clumps descend from the sun's corona. This breakthrough challenges previous models and enhances our understanding of solar dynamics, potentially improving space weather predictions.
  • Launch Roundup: SpaceX dominates the launch schedule with five Falcon 9 missions this week, including Starlink satellite deployments and Amazon's Project Kuiper. Blue Origin also contributes with its New Shepard mission, marking significant advancements in suborbital space travel.
  • Ground-Based Imaging Breakthrough: Astronomers at Johns Hopkins have developed a new algorithm that enhances ground-based telescope images to match space telescope clarity. This innovative technique could revolutionize ground-based astronomy, allowing for deeper, clearer observations of the cosmos.

00:00:00 --> 00:00:02 Anna: Welcome to Astronomy Daily. I'm Anna.

00:00:02 --> 00:00:05 Avery: And I'm Avery. It's great to have you with us

00:00:05 --> 00:00:08 for your essential daily update on everything

00:00:08 --> 00:00:11 happening in the cosmos. We've got a packed

00:00:11 --> 00:00:12 show for you today.

00:00:12 --> 00:00:14 Anna: Indeed, we'll be talking about exciting

00:00:14 --> 00:00:17 comets, including an interstellar visitor.

00:00:17 --> 00:00:19 We'll delve into surprising findings about

00:00:19 --> 00:00:22 the early universe, uncover why it rains on

00:00:22 --> 00:00:24 the sun, and catch up on the latest rocket

00:00:24 --> 00:00:25 launches.

00:00:25 --> 00:00:26 Avery: Absolutely, Anna.

00:00:26 --> 00:00:29 Uh, let's kick things off with Comet C by

00:00:29 --> 00:00:32 2025. A6lem this

00:00:32 --> 00:00:35 comet is putting on an encore appearance at

00:00:35 --> 00:00:38 dusk this October, joining Comet R2

00:00:38 --> 00:00:40 Swan in what promises to be a

00:00:40 --> 00:00:42 fantastic show for observers.

00:00:43 --> 00:00:45 Anna: Asics LEMMON slides past Earth at about twice

00:00:45 --> 00:00:48 the distance of R2 Swan just 24 hours

00:00:48 --> 00:00:51 later. Both are currently fine objects for

00:00:51 --> 00:00:53 binoculars or a small telescope vying for top

00:00:53 --> 00:00:55 spot at around magnitude

00:00:55 --> 00:00:57 6A6 LEMMON was.

00:00:57 --> 00:01:00 Avery: Discovered by astronomer D. Carson Fuls

00:01:01 --> 00:01:03 during the Mount Lemmon Sky Survey back on

00:01:03 --> 00:01:06 January 3rd. It's proven to be a

00:01:06 --> 00:01:09 dependable performer. Crossing from the

00:01:09 --> 00:01:12 constellation Leominer into Ursa

00:01:12 --> 00:01:15 Major recently just below the famous Big.

00:01:15 --> 00:01:17 Anna: Dipper A6 LEMMON is on a roughly

00:01:17 --> 00:01:20 1350 year inbound orbit. Its path

00:01:20 --> 00:01:22 will be slightly tweaked by Jupiter. It

00:01:22 --> 00:01:24 reaches its closest point to the sun or

00:01:24 --> 00:01:27 perihelion at Ah, 0.53

00:01:27 --> 00:01:29 astronomical units from the sun on November

00:01:29 --> 00:01:29 8th.

00:01:30 --> 00:01:33 Avery: Then it's off to a chilly aphelion beyond the

00:01:33 --> 00:01:36 main kuiper belt at uh, 219 AU

00:01:36 --> 00:01:39 from the sun around 3175 AD.

00:01:39 --> 00:01:42 Anna: Good news is a 6 lemon seems to be

00:01:42 --> 00:01:44 brightening slightly ahead of predictions. It

00:01:44 --> 00:01:47 maxes out in northern declination on October

00:01:47 --> 00:01:49 10th and actually goes circumpolar for

00:01:49 --> 00:01:52 observers north of the 50th parallel,

00:01:52 --> 00:01:55 roughly above London and Vancouver around the

00:01:55 --> 00:01:55 same date.

00:01:56 --> 00:01:58 Avery: From mid latitude Northern Hemisphere

00:01:58 --> 00:02:00 observers, it's transitioning to the evening

00:02:00 --> 00:02:03 sky. By mid month a 6 lemon will

00:02:03 --> 00:02:06 hug the western horizon, never getting much

00:02:06 --> 00:02:08 higher than 20 degrees an hour after sunset.

00:02:08 --> 00:02:11 Unlike R2 Swan, we can always hope.

00:02:11 --> 00:02:13 Anna: For an outburst to enhance its visibility.

00:02:13 --> 00:02:15 Remember, comet magnitudes can deceive.

00:02:16 --> 00:02:18 A comet's light gets smeared out, often

00:02:18 --> 00:02:20 needing to be around third magnitude to be

00:02:20 --> 00:02:21 seen without binoculars.

00:02:22 --> 00:02:24 Avery: To actually look like a comet with a fuzzy

00:02:24 --> 00:02:27 head and a tail, it needs to be even brighter

00:02:27 --> 00:02:30 around first magnitude or better. But

00:02:30 --> 00:02:32 don't let this deter you from your cometary

00:02:32 --> 00:02:32 quest.

00:02:33 --> 00:02:36 Anna: Both Artoo Swan and Asics LEMMON should make

00:02:36 --> 00:02:37 excellent binocular objects right around

00:02:37 --> 00:02:40 Halloween. Asics LEMMON then starts to

00:02:40 --> 00:02:43 head southward and will favor the Northern

00:02:43 --> 00:02:45 Hemisphere into November as it continues its

00:02:45 --> 00:02:47 long journey out of the solar system.

00:02:48 --> 00:02:50 Avery: And for those with large telescopes, there's

00:02:50 --> 00:02:52 an extra special treat interstellar comet

00:02:52 --> 00:02:55 3I Atlas. Also visible

00:02:55 --> 00:02:58 as a 11th magnitude object, it'll just look

00:02:58 --> 00:03:01 like a dot, but it's a rare interloper from

00:03:01 --> 00:03:03 beyond our solar system. Precise coordinates

00:03:03 --> 00:03:06 are needed, but sites like Kevin's above

00:03:06 --> 00:03:07 offer excellent comet pages.

00:03:08 --> 00:03:10 Anna: Astrophotographer Elliot Herman noted that if

00:03:10 --> 00:03:13 a comet is three or four, it will be a

00:03:13 --> 00:03:16 nice binocular object, suggesting apps like

00:03:16 --> 00:03:19 Stellarium to locate it. Observing Comet

00:03:19 --> 00:03:21 Asics LEMMON is as easy as sweeping at low

00:03:21 --> 00:03:24 power, and even a tripod mounted DSLR

00:03:24 --> 00:03:26 with 10 to 30 second exposures should reveal

00:03:26 --> 00:03:28 it as a small green blob.

00:03:28 --> 00:03:30 Avery: That's fantastic advice.

00:03:30 --> 00:03:32 And speaking of interstellar comets, Anna,

00:03:32 --> 00:03:35 let's dive deeper into three IAT

00:03:35 --> 00:03:38 LAs. This object has really

00:03:38 --> 00:03:40 captured the astronomical spotlight since its

00:03:40 --> 00:03:42 discovery in July 2025.

00:03:43 --> 00:03:44 Anna: It's definitely captured a lot of attention.

00:03:45 --> 00:03:48 To clarify, 3i Atlas is actually the third

00:03:48 --> 00:03:51 interstellar object ever discovered after

00:03:51 --> 00:03:54 1eye Oumuamua in 2017 and

00:03:54 --> 00:03:56 2i Borisov in 2019.

00:03:56 --> 00:03:59 It was found by the Atlas station in Chile.

00:03:59 --> 00:04:02 Avery: 3I Atlas, like Borisov,

00:04:02 --> 00:04:04 is clearly a comet, but it's thought to be

00:04:04 --> 00:04:06 quite large with a nucleus estimated at about

00:04:06 --> 00:04:09 a kilometer in diameter, roughly the length

00:04:09 --> 00:04:10 of 10 football fields.

00:04:10 --> 00:04:12 Anna: One of its most unusual features is that its

00:04:12 --> 00:04:15 dust tail appears to point towards the Sun.

00:04:15 --> 00:04:18 Normally, solar radiation pushes comet tails

00:04:18 --> 00:04:21 away. 3i Atlas has that

00:04:21 --> 00:04:24 faint normal tail but also heavier dust

00:04:24 --> 00:04:27 grains pushed by its own internal activity.

00:04:27 --> 00:04:30 Avery: Because the Sun's energy increases that

00:04:30 --> 00:04:33 internal activity, dust is primarily

00:04:33 --> 00:04:36 pushed out towards the sun, creating this

00:04:36 --> 00:04:38 backward looking tail. Initial studies

00:04:38 --> 00:04:41 suggest this comet may be between 3 and

00:04:41 --> 00:04:44 14 billion years old, potentially older

00:04:44 --> 00:04:46 than our solar system, an.

00:04:46 --> 00:04:49 Anna: Ancient relic Tracing its exact galactic

00:04:49 --> 00:04:51 origin is almost impossible as its

00:04:51 --> 00:04:54 trajectory has been nudged countless times.

00:04:54 --> 00:04:57 However, JWST and SphereX

00:04:57 --> 00:04:59 observations show it's rich in carbon

00:04:59 --> 00:05:02 dioxide, suggesting it formed far from its

00:05:02 --> 00:05:04 parent star in a very cold environment.

00:05:04 --> 00:05:07 Avery: So while we don't know where it came from, we

00:05:07 --> 00:05:09 do know where it's going. 3i

00:05:09 --> 00:05:12 Atlas reaches perihelion, its closest point

00:05:12 --> 00:05:14 to the sun around October 29th.

00:05:15 --> 00:05:18 Then it will pass 0.65 AU

00:05:18 --> 00:05:20 from Venus on November 3rd.

00:05:20 --> 00:05:23 Anna: And here's an exciting ESA's Juice

00:05:23 --> 00:05:25 spacecraft en route to Jupiter will attempt

00:05:25 --> 00:05:28 to observe 3i Atlas. Its

00:05:28 --> 00:05:30 closest approach to Earth will be December

00:05:30 --> 00:05:32 19th. After passing Jupiter in

00:05:32 --> 00:05:35 March 2026, it will leave our solar

00:05:35 --> 00:05:35 system.

00:05:36 --> 00:05:39 Avery: It's incredibly fast too, at

00:05:39 --> 00:05:41 perihelion it's expected to hit 68

00:05:41 --> 00:05:44 kilometers per second. 3 IA

00:05:44 --> 00:05:47 Atlas certainly won't be the last. With

00:05:47 --> 00:05:49 powerful survey telescopes like the Vera

00:05:49 --> 00:05:51 Rubin Observatory coming online,

00:05:51 --> 00:05:54 astronomers expect to discover many more

00:05:54 --> 00:05:57 interstellar objects, giving us unique

00:05:57 --> 00:06:00 insights into the universe from interstellar

00:06:00 --> 00:06:00 wanderers.

00:06:00 --> 00:06:02 Anna: Let's turn our attention to the very

00:06:02 --> 00:06:05 beginning of everything. New research from

00:06:05 --> 00:06:07 astronomers in Australia suggests that the

00:06:07 --> 00:06:09 early universe was surprisingly warmer than

00:06:09 --> 00:06:12 expected, particularly around 800 million

00:06:12 --> 00:06:13 years after the Big Bang.

00:06:14 --> 00:06:16 Avery: This discovery specifically probes the epoch

00:06:16 --> 00:06:19 of reionization. The universe

00:06:19 --> 00:06:22 originated 13.8 billion years ago.

00:06:22 --> 00:06:25 Initially, it was a hot soup of particles,

00:06:26 --> 00:06:28 then cooled enough for hydrogen and helium

00:06:28 --> 00:06:31 nuclei to form with three electrons,

00:06:32 --> 00:06:33 making the universe opaque.

00:06:34 --> 00:06:36 Anna: About 380 years after the Big

00:06:36 --> 00:06:39 Bang, it cooled further, allowing the first

00:06:39 --> 00:06:42 neutral atoms to form and light could finally

00:06:42 --> 00:06:45 travel freely, creating the cosmic

00:06:45 --> 00:06:46 microwave background we observe today.

00:06:47 --> 00:06:50 Then came the Dark ages. For about 200

00:06:50 --> 00:06:52 million years, a dark expanse of mostly

00:06:52 --> 00:06:53 hydrogen.

00:06:53 --> 00:06:56 Avery: The epoch of reionization ended these

00:06:56 --> 00:06:58 dark ages when the first stars ignited.

00:06:59 --> 00:07:02 These early stars emitted ultraviolet light

00:07:02 --> 00:07:04 energetic enough to ionize the surrounding

00:07:04 --> 00:07:07 hydrogen gas, clearing the cosmic fog

00:07:07 --> 00:07:10 and making the universe transparent, allowing

00:07:10 --> 00:07:13 starlight to eventually reach our telescopes.

00:07:13 --> 00:07:16 This period is incredibly important because

00:07:16 --> 00:07:18 it's when the first stars and galaxies

00:07:18 --> 00:07:18 formed.

00:07:19 --> 00:07:20 Anna: So what about its temperature? Researchers

00:07:20 --> 00:07:22 used the Murchison Wide Field Array radio

00:07:22 --> 00:07:25 telescope, analyzing a decade's worth of data

00:07:25 --> 00:07:28 from 2013 to 2023. They looked for

00:07:28 --> 00:07:31 the faint signal of the 21cm

00:07:31 --> 00:07:33 hydrogen line. From this extremely distant

00:07:33 --> 00:07:36 epoch, red shifted to longer radio

00:07:36 --> 00:07:36 wavelengths.

00:07:37 --> 00:07:40 Avery: The challenge, as Ridima Nun Hoki explained,

00:07:40 --> 00:07:42 was meticulously cleaning the data to remove

00:07:42 --> 00:07:45 all the foreground signals, emission from

00:07:45 --> 00:07:48 closer objects like stars and galaxies,

00:07:48 --> 00:07:50 interference from Earth's atmosphere, and

00:07:50 --> 00:07:53 even noise from the telescope itself. It's a

00:07:53 --> 00:07:56 massive data science undertaking, and.

00:07:56 --> 00:07:58 Anna: After all that careful work, they didn't find

00:07:58 --> 00:08:00 the telltale characteristics that would

00:08:00 --> 00:08:03 indicate a very cold universe. This implies

00:08:03 --> 00:08:05 the gas between galaxies was heated.

00:08:06 --> 00:08:08 Catherine Trott noted this rules out very

00:08:08 --> 00:08:10 cold reionization. A, uh, really interesting

00:08:10 --> 00:08:10 finding.

00:08:11 --> 00:08:13 Avery: The new research suggests this warmer early

00:08:13 --> 00:08:16 universe was heated by x rays from early

00:08:16 --> 00:08:19 sources, specifically nascent black holes and

00:08:19 --> 00:08:22 the remains of dead stars. And it helps us

00:08:22 --> 00:08:24 understand the conditions that allowed light

00:08:24 --> 00:08:25 to eventually break free.

00:08:26 --> 00:08:28 Anna: Looking ahead, the team will apply these

00:08:28 --> 00:08:31 cutting edge data analysis techniques to even

00:08:31 --> 00:08:34 higher quality data from the Square Kilometer

00:08:34 --> 00:08:37 Array telescopes currently under construction

00:08:37 --> 00:08:40 to fine tune our understanding of this

00:08:40 --> 00:08:41 critical epoch.

00:08:41 --> 00:08:43 Avery: Moving from the early universe to our own

00:08:43 --> 00:08:46 star, the Sun. Prepare for a surprising

00:08:46 --> 00:08:49 revelation. Scientists at the University of

00:08:49 --> 00:08:51 Hawaii have finally discovered why it appears

00:08:51 --> 00:08:54 to rain on the Sun. Changing

00:08:54 --> 00:08:56 elemental makeup, um, drives these mysterious

00:08:56 --> 00:08:57 downpours of plasma.

00:08:58 --> 00:09:01 Anna: That's right, Avery. This solar rain

00:09:01 --> 00:09:03 involves cooler, denser clumps of plasma that

00:09:03 --> 00:09:06 condense high in the sun's corona and then

00:09:06 --> 00:09:09 descend back towards the surface. Researchers

00:09:09 --> 00:09:11 were puzzled by how rapidly this could happen

00:09:11 --> 00:09:14 during intense solar flares, and.

00:09:14 --> 00:09:16 Avery: The long standing mystery has been solved by

00:09:16 --> 00:09:18 Luke Bennevitz, uh, a graduate student, and

00:09:18 --> 00:09:20 astronomer Jeffrey Reap. Their findings,

00:09:20 --> 00:09:22 published in the Astrophysical Journal,

00:09:23 --> 00:09:25 provide an essential update to solar models

00:09:25 --> 00:09:27 that have puzzled scientists for decades.

00:09:27 --> 00:09:30 Anna: Bennovitz explained that current models

00:09:30 --> 00:09:32 assume the distribution of elements in the

00:09:32 --> 00:09:35 corona is constant, but their work shows

00:09:35 --> 00:09:37 that when elements like iron are allowed to

00:09:37 --> 00:09:39 change with time, the models finally match

00:09:39 --> 00:09:42 what's observed. This means the physics truly

00:09:42 --> 00:09:44 comes alive and feels real.

00:09:45 --> 00:09:47 Avery: This is a significant breakthrough. Earlier

00:09:47 --> 00:09:50 models assumed elemental distributions were

00:09:50 --> 00:09:53 constant, which didn't match fast acting

00:09:53 --> 00:09:56 solar flares. This new understanding

00:09:56 --> 00:09:58 of shifting elemental abundances explains

00:09:58 --> 00:10:01 how rain can form so quickly. As Arip

00:10:01 --> 00:10:04 noted, if our models haven't treated

00:10:04 --> 00:10:07 abundances properly, cooling times were

00:10:07 --> 00:10:09 likely overestimated, meaning a lot of new

00:10:09 --> 00:10:11 work is needed on coronal heating.

00:10:12 --> 00:10:14 Anna: This discovery has implications far beyond

00:10:14 --> 00:10:17 coronal rain, challenging long standing

00:10:17 --> 00:10:18 models that assumed fixed elemental

00:10:18 --> 00:10:21 abundances in the Sun's atmosphere. It

00:10:21 --> 00:10:24 pushes researchers to rethink how the sun's

00:10:24 --> 00:10:26 outer layers behave and how energy moves

00:10:26 --> 00:10:28 through its atmosphere, potentially aiding

00:10:28 --> 00:10:29 space.

00:10:29 --> 00:10:32 Avery: Weather prediction that's crucial for our

00:10:32 --> 00:10:33 technological society.

00:10:34 --> 00:10:36 Now let's blast off into our launch

00:10:36 --> 00:10:39 roundup. For the first week of October

00:10:39 --> 00:10:42 2025, SpaceX is

00:10:42 --> 00:10:44 absolutely dominating the manifest with

00:10:44 --> 00:10:47 five Falcon 9 missions scheduled.

00:10:48 --> 00:10:50 Four of these will launch more satellites

00:10:50 --> 00:10:52 into their Starlink Internet Constellation,

00:10:52 --> 00:10:54 and the fifth will carry satellites for

00:10:54 --> 00:10:56 Amazon's Project Cooper first.

00:10:56 --> 00:10:59 Starlink Group 1059 lifted off on

00:10:59 --> 00:11:02 Tuesday, October 7th at 12:10am

00:11:02 --> 00:11:05 EDT from Cape Canaveral. Its

00:11:05 --> 00:11:07 Falcon 9 booster B1090

00:11:07 --> 00:11:10 completed its eighth flight and landed

00:11:10 --> 00:11:12 successfully just hours later. On Tuesday

00:11:12 --> 00:11:15 Evening, Starlink Group 1117

00:11:15 --> 00:11:18 launched from Vandenberg Space Force Base in

00:11:18 --> 00:11:21 California, carrying another 28

00:11:21 --> 00:11:23 Starlink V2 mini satellites into low

00:11:23 --> 00:11:26 Earth orbit. That's a rapid turnaround even

00:11:26 --> 00:11:29 for SpaceX. Blue Origin also

00:11:29 --> 00:11:32 joins the schedule with their 36th New

00:11:32 --> 00:11:33 Shepard mission, planned for Wednesday,

00:11:33 --> 00:11:36 October 8, carrying six people to

00:11:36 --> 00:11:39 suborbital space. This marks New

00:11:39 --> 00:11:41 Shepard's 15th crewed mission and its eighth

00:11:41 --> 00:11:44 flight this year, doubling their total

00:11:44 --> 00:11:46 flights from 2024, a significant

00:11:46 --> 00:11:49 increase. Then on October 9,

00:11:49 --> 00:11:51 another Falcon 9 will launch the

00:11:51 --> 00:11:54 KF03 mission for Amazon's Project

00:11:54 --> 00:11:56 Kuiper sending 24 communications

00:11:56 --> 00:11:59 satellites into LEO. This adds to the

00:11:59 --> 00:12:02 12 nine Kuiper satellites already deployed,

00:12:02 --> 00:12:04 aiming for a total of

00:12:04 --> 00:12:06 3. Booster

00:12:06 --> 00:12:09 B1091 will be making its second flight with a

00:12:09 --> 00:12:12 quick 60 day turnaround. Meanwhile,

00:12:12 --> 00:12:15 in China, CASC is expected to launch

00:12:15 --> 00:12:18 the fifth Changzang 8A rocket from

00:12:18 --> 00:12:21 Wencheng, a mission initially delayed by

00:12:21 --> 00:12:24 Typhoon Makmo. And to cap off SpaceX's

00:12:24 --> 00:12:26 busy week, two more Starlink missions, Group

00:12:26 --> 00:12:29 1052 and 1119, are slated

00:12:29 --> 00:12:32 for October 12th. This will make Falcon

00:12:32 --> 00:12:34 9's 130th mission of

00:12:34 --> 00:12:37 2025 and 548th over,

00:12:38 --> 00:12:39 what, a week for launches?

00:12:40 --> 00:12:42 Anna: That's an incredible pace, Avery finally

00:12:42 --> 00:12:44 today, Johns Hopkins astronomers have

00:12:44 --> 00:12:46 developed a new algorithm that can render

00:12:46 --> 00:12:49 images from ground based telescopes as clear

00:12:49 --> 00:12:51 as those taken from space. This

00:12:51 --> 00:12:53 groundbreaking method uses algorithms to

00:12:53 --> 00:12:56 strip away atmospheric interference, making

00:12:56 --> 00:12:58 it possible for earthbound instruments to

00:12:58 --> 00:13:00 produce the deepest, clearest images.

00:13:01 --> 00:13:03 Thomas Budavari says it allows us to see

00:13:03 --> 00:13:06 farther, fainter targets Even the most

00:13:06 --> 00:13:09 powerful ground based telescopes struggle

00:13:09 --> 00:13:12 with Earth's atmosphere. Variations in

00:13:12 --> 00:13:14 temperature, pressure and air conditions

00:13:14 --> 00:13:17 cause subtle but significant distortions.

00:13:17 --> 00:13:20 Traditional techniques often blur fine

00:13:20 --> 00:13:22 details or introduce grainy artifacts.

00:13:23 --> 00:13:26 The new solution, called ImageMM,

00:13:26 --> 00:13:28 models how light travels through our restless

00:13:28 --> 00:13:31 atmosphere, effectively stripping away

00:13:31 --> 00:13:34 distortions. Yashil Sukhardeep

00:13:34 --> 00:13:37 described our algorithms learn to see past

00:13:37 --> 00:13:39 that curtain, reconstructing the still sharp

00:13:39 --> 00:13:42 image hidden behind it. Early tests

00:13:42 --> 00:13:45 with images from the Subaru Telescope, one of

00:13:45 --> 00:13:47 the world's largest, restored blurry and

00:13:47 --> 00:13:49 noisy images in a matter of seconds,

00:13:49 --> 00:13:52 revealing intricate spiral galaxy structures

00:13:52 --> 00:13:55 with unprecedented clarity. These

00:13:55 --> 00:13:57 images were specifically acquired to test for

00:13:57 --> 00:13:59 similar quality as future captures by the

00:13:59 --> 00:14:01 Vera C Rubin Observatory.

00:14:02 --> 00:14:04 Sukhardeep explained that their framework can

00:14:04 --> 00:14:06 recover a near perfect image from a series of

00:14:06 --> 00:14:09 imperfect observations, getting as close as

00:14:09 --> 00:14:12 possible to ground truth. This is

00:14:12 --> 00:14:14 critical for astronomers who need to

00:14:14 --> 00:14:16 accurately measure the shapes of objects.

00:14:16 --> 00:14:19 While space telescopes offer superior deep

00:14:19 --> 00:14:22 imaging capabilities, they cover only a tiny

00:14:22 --> 00:14:25 fraction of the observable sky. Ground

00:14:25 --> 00:14:27 based facilities like the Rubin Observatory,

00:14:27 --> 00:14:30 however, will image the entire visible sky

00:14:30 --> 00:14:32 every few days. With this new technique,

00:14:32 --> 00:14:35 hundreds of ground based observations can be

00:14:35 --> 00:14:37 turned into images almost comparable to what

00:14:37 --> 00:14:39 was previously only achievable with a space

00:14:39 --> 00:14:42 telescope. This is a massive leap for ground

00:14:42 --> 00:14:43 based astronomy.

00:14:43 --> 00:14:46 Avery: What an incredible collection of stories

00:14:46 --> 00:14:48 today. Ana uh, it's clear the cosmos is

00:14:48 --> 00:14:50 always full of surprises.

00:14:50 --> 00:14:52 Anna: It certainly is. Avery and that's all we have

00:14:52 --> 00:14:54 time for today. Thank you for tuning in to

00:14:54 --> 00:14:55 Astronomy Daily.

00:14:55 --> 00:14:58 Avery: Join us tomorrow for more space and astronomy

00:14:58 --> 00:15:00 news. Until then, keep looking up.
