Transcript
- 0:00Hello and welcome to Astronomy Daily,
- 0:02the podcast that brings you the latest
- 0:04news from across the cosmos. I'm your
- 0:07host, Avery.
- 0:08>> And I'm Anna. It's great to be with you.
- 0:10We've got a busy show today. From the
- 0:13largest rotating structure ever observed
- 0:15to man is in space.
- 0:17>> That's right. We'll also be looking at
- 0:19China's ambitious plans to find Earth
- 0:222.0, know checking in on a commander
- 0:25swap at the International Space Station
- 0:27and celebrating an Emmy win for NASA.
- 0:30So, let's get started. First up, an
- 0:33incredible discovery that's being
- 0:34compared to a cosmic teacup ride.
- 0:37Astronomers have found a string of 14
- 0:40galaxies that are all spinning in the
- 0:42same direction as the massive structure
- 0:44they belong to.
- 0:46>> And this isn't just any structure. It's
- 0:48a cosmic filament, a gigantic threadlike
- 0:51formation made of dark matter, galaxies,
- 0:54and gas. They're the biggest things in
- 0:56the universe, forming a kind of cosmic
- 0:59web.
- 1:00>> Exactly. This particular filament is
- 1:02about 50 million light-years along and
- 1:04is rotating at a staggering velocity of
- 1:07110 km/s.
- 1:09>> Wow. 110 km/s.
- 1:13And the galaxies within it are spinning
- 1:16along with it. That's the amazing part.
- 1:18Researchers looked at a section of this
- 1:20filament about 140 million lighty years
- 1:22away. They found these 14 galaxies, all
- 1:26rich in hydrogen gas, moving in a way
- 1:28that suggests the whole structure is
- 1:30rotating. And more surprisingly, many of
- 1:33the galaxies themselves are spinning in
- 1:35the same direction as the filament.
- 1:37>> Right. The lead researcher, Llaya Jung,
- 1:40used a great analogy. She said it's like
- 1:42the teacups ride at a theme park.
- 1:44>> Mhm. Each galaxy is a spinning teacup
- 1:47and the whole platform, the cosmic
- 1:49filament, is rotating too. This dual
- 1:52motion gives us a rare insight into how
- 1:54galaxies get their spin from the cosmic
- 1:57web they inhabit. It suggests these
- 1:59larger structures have a much stronger
- 2:02influence than we previously thought.
- 2:04>> A truly mind-bending discovery. Now,
- 2:06let's shift our focus a bit closer to
- 2:08home and look at the future of space
- 2:11exploration. The China National Space
- 2:13Agency or CNSA has outlined some very
- 2:17ambitious plans.
- 2:19>> That's right. In a video titled Earth
- 2:212.0, China's plan to find new Earth,
- 2:24they detailed four major upcoming
- 2:26missions scheduled for their 15th 5-year
- 2:28plan between 2026 and 2030.
- 2:32>> And these missions cover a huge range of
- 2:34objectives. They're planning a
- 2:36radioastronomy experiment for the far
- 2:38side of the moon, a solar observatory to
- 2:40study space weather,
- 2:42>> duts, a space telescope to monitor black
- 2:44holes and neutron stars, and of course,
- 2:47the exoplanet hunting satellite that
- 2:49will search for those Earthlike planets.
- 2:51>> It's a clear statement of intent. China
- 2:54is positioning itself to be at the
- 2:56absolute forefront of space science and
- 2:58exploration in the coming decade.
- 3:00>> Absolutely. Now for a couple of updates
- 3:02from the International Space Station
- 3:04where it's been a busy few days. First
- 3:06up, a change of leadership.
- 3:08>> Yes, Expedition 73 is handing the reigns
- 3:11over to Expedition 74. On Sunday,
- 3:14veteran Rose Coast Most Cosminaut Sergey
- 3:16Rissov will pass the symbolic station
- 3:19key to four-time NASA astronaut Mike
- 3:21Fininky.
- 3:22>> And that handover marks the beginning of
- 3:24the end of the mission for three crew
- 3:26members. Rissov along with flight
- 3:28engineers Alexi Zubritzky and NASA's
- 3:31Johnny Kim are packing up for their
- 3:32return trip to Earth inside the Soyuse
- 3:35MS27 spacecraft.
- 3:37>> Safe travels to them. But while the crew
- 3:39is changing, the science never stops.
- 3:42And our next story from the ISS is a
- 3:44fascinating one. Anna, why are
- 3:46scientists studying mayonnaise in space?
- 3:49>> It sounds strange, but it's all about
- 3:51understanding something called soft
- 3:53matter. This includes things like gels,
- 3:55foams, collids, and mayonnaise. These
- 3:59substances have internal structures that
- 4:01reorganize very slowly over time. Think
- 4:04about how sunscreen can change in the
- 4:06cabinet or how a cream loses
- 4:08effectiveness.
- 4:09>> Okay, that makes sense. And studying
- 4:11this process on Earth is complicated by
- 4:13gravity. Right.
- 4:14>> Exactly. So, researchers developed an
- 4:17experiment called Kolis, which is now
- 4:19operating on the space station. It uses
- 4:22sophisticated optical techniques to look
- 4:24inside these materials without
- 4:26disturbing them in a microgravity
- 4:28environment.
- 4:29>> And are there any results yet?
- 4:31>> There are, and they're already
- 4:32surprising. Early data shows that
- 4:34gravity affects the structure of soft
- 4:37matter much more dramatically than
- 4:39anyone expected. This could have huge
- 4:41implications for everything from food
- 4:43production to pharmaceuticals right here
- 4:46on Earth. Incredible what we can learn
- 4:48from looking at everyday items in an
- 4:50extraordinary place. Next, let's talk
- 4:52comets. NASA's Punch mission has
- 4:54released an incredible 40-day time lapse
- 4:56of comet Swan.
- 4:58>> This might be the longest, most frequent
- 5:00observation of a comet ever recorded.
- 5:03The spacecraft imaged Comet C 2025 R2,
- 5:07also known as Swan, every 4 minutes from
- 5:10late August to early October.
- 5:12>> The video is just stunning. You can see
- 5:14the comet gliding through space with its
- 5:16bluish green coma and glowing tail
- 5:18clearly visible. That glow is from the
- 5:20sun's heat vaporizing the comet's ices,
- 5:23a process called sublimation.
- 5:24>> Mhm. And there was an unexpected guest
- 5:27star in the video. The comet happened to
- 5:29be sharing the same patch of sky with
- 5:31the famous interstellar visitor Threei
- 5:33Atlas, which you can just glimpse in the
- 5:36footage. A true cosmic photo bomb.
- 5:38>> Fantastic. And for our final story
- 5:40today, we're switching from scientific
- 5:42observation to television production.
- 5:44NASA has won another Emmy award.
- 5:47>> They have. This time it's for their
- 5:49broadcast of the total solar eclipse
- 5:51back on April 8th, 2024. The Academy of
- 5:54Television Arts and Sciences recognized
- 5:56them for excellence in production
- 5:58technology.
- 5:59>> And it was a massive undertaking. The
- 6:01agency called it the most complex life
- 6:03project they've ever produced. The
- 6:05broadcast was 3 hours long, covered
- 6:07seven American states in two countries,
- 6:10and had hosts and correspondents all
- 6:11over the path of totality.
- 6:13>> The effort definitely paid off. The
- 6:16broadcast pulled in nearly 40 million
- 6:18views across all of NASA's channels,
- 6:20including their streaming service NASA
- 6:22Plus. From watch parties in libraries to
- 6:25Times Square, people all over the world
- 6:27tuned in.
- 6:28>> A well-deserved win for a truly
- 6:30spectacular production that brought a
- 6:32celestial wonder to millions. And that
- 6:34unfortunately is all the time we have
- 6:36for today.
