SphereX's Cosmic Quest, Lunar Triumphs and Trials, and the Universe's Black Hole Mystery: S04E63

0:00 Speaker 1: Welcome to Astronomy Daily. I'm Anna and you're in for

0:03 Speaker 1: quite a fascinating show today. We've got a great lineup

0:06 Speaker 1: of stories that showcase just how rapidly our understanding of

0:09 Speaker 1: the cosmos continues to evolve. From NASA's ambitious new SPHEREx

0:14 Speaker 1: mission beginning its journey to map hundreds of millions of galaxies,

0:18 Speaker 1: to some dramatic developments in lunar exploration, and a mind

0:22 Speaker 1: bending discovery from the James Webb Space Telescope that suggests

0:26 Speaker 1: our entire universe might be inside a black hole. Yes,

0:30 Speaker 1: you heard that right. We'll also look at a groundbreaking

0:32 Speaker 1: new map of our galaxy that's helping astronomers see through

0:35 Speaker 1: the cosmic dust that surrounds us. It's an exciting time

0:39 Speaker 1: in space exploration, and we've got all the latest developments

0:42 Speaker 1: coming right up. NASA has just confirmed a major milestone

0:47 Speaker 1: in space exploration with their SPHEREx mission successfully establishing contact

0:52 Speaker 1: and beginning its groundbreaking science operations. This extraordinary observatory is

0:57 Speaker 1: now preparing for what promises to be a revolution two

1:00 Speaker 1: year survey of our cosmic neighborhood. SPHEREx, which stands for

1:05 Speaker 1: Spectrophotometer for the history of the Universe, epic of realization,

1:09 Speaker 1: and ices. Explorer will undertake the ambitious task of mapping

1:13 Speaker 1: more than four hundred and fifty million galaxies and over

1:16 Speaker 1: one hundred million stars in our own Milky Way. But

1:19 Speaker 1: this isn't just about counting celestial objects. The mission aims

1:23 Speaker 1: to answer some of the most fundamental questions about our universe.

1:27 Speaker 1: In the coming weeks, mission controllers will be fine tuning

1:29 Speaker 1: the observatory, conducting crucial calibrations, and cooling the telescope to

1:34 Speaker 1: its optimal operating temperature. Once everything is properly aligned and configured,

1:40 Speaker 1: SPHEREx will begin creating what will become the most comprehensive

1:43 Speaker 1: three D map of the entire sky ever attempted. One

1:47 Speaker 1: of the mission's primary objectives is to investigate a phenomenon

1:50 Speaker 1: called cosmic inflation, that brief moment just after the Big Bang,

1:54 Speaker 1: when the universe expanded faster than the speed of light.

1:58 Speaker 1: The telescope will also measure the collective glow from galaxies,

2:01 Speaker 1: including those that are too faint or distant to be

2:04 Speaker 1: observed individually. Perhaps most intriguingly, SPHEREx will search our galaxy

2:09 Speaker 1: for hidden reservoirs of water carbon dioxide and other ingredients

2:13 Speaker 1: essential for life. This could provide valuable insights into how

2:17 Speaker 1: common these life supporting materials are throughout the cosmos. What

2:21 Speaker 1: makes SPHEREx particularly special is its ability to complement the

2:25 Speaker 1: work of other space telescopes like Hubble and James Webb.

2:30 Speaker 1: While those observatories focus on specific targets in great detail,

2:34 Speaker 1: SPHEREx will scan vast sections of the sky quickly, creating

2:38 Speaker 1: an unprecedented cosmic sensus. Better yet, all of this data

2:42 Speaker 1: will be freely available to scientists worldwide, essentially providing a

2:46 Speaker 1: new encyclopedia of hundreds of millions of cosmic objects. The

2:51 Speaker 1: past few weeks have brought us a mixed bag of

2:53 Speaker 1: lunar landing updates, with some remarkable achievements alongside sobering challenges.

2:59 Speaker 1: Let's start with the exciting news from Firefly Aerospace's Blue

3:02 Speaker 1: Ghost mission, which touched down successfully in the Moon's mare

3:06 Speaker 1: Chrisium region on March second. This landing gave us something

3:10 Speaker 1: we've never seen before, unprecedented footage of a lunar touchdown

3:14 Speaker 1: captured by special cameras designed to study how spacecraft interact

3:18 Speaker 1: with the Moon's surface. The Scalpuss camera system a board

3:22 Speaker 1: blue Ghost recorded the entire descent sequence, starting from about

3:26 Speaker 1: ninety one feet above the surface. These images showed us

3:29 Speaker 1: exactly what happens when a spacecraft's engine plumes first interact

3:33 Speaker 1: with lunar soil at around forty nine feet up, creating

3:37 Speaker 1: a fascinating dance of dust and regolith that will help

3:40 Speaker 1: engineers design safer future landings. If you'd like to see

3:44 Speaker 1: some of the video footage and check out more details,

3:47 Speaker 1: take a look at our latest blog post on our

3:49 Speaker 1: website at Astronomy Daily dot io. However, not all recent

3:53 Speaker 1: lunar missions have enjoyed such success intuitive machines. Athena Lander

3:57 Speaker 1: faced significant challenges during its landing Dame Tempt last week.

4:01 Speaker 1: While the spacecraft performed flawlessly during its journey to the Moon,

4:04 Speaker 1: a critical altimeter failure meant it couldn't determine its exact

4:08 Speaker 1: height above the surface during the final descent phase. This

4:12 Speaker 1: led to a dramatic landing where Athena struck a plateau,

4:15 Speaker 1: toppled over and actually skidded across the lunar surface, rotating

4:19 Speaker 1: several times before coming to rest in a small shadowed crater.

4:24 Speaker 1: While the spacecraft managed to survive this rough landing. The

4:28 Speaker 1: impact kicked up regolith that covered its solar panels, severely

4:32 Speaker 1: limiting its power generation capabilities. In even more challenging news,

4:37 Speaker 1: NASA's Lunar Trailblazer mission has been struggling since shortly after

4:40 Speaker 1: its launch on February twenty sixth. Mission controllers lost contact

4:45 Speaker 1: with the small satellite just one day after launch, and

4:48 Speaker 1: despite continued efforts to re establish communications through NASA's Deep

4:52 Speaker 1: Space Network and other ground stations, the situation remains uncertain.

4:57 Speaker 1: These contrasting outcomes highlight the inherentallenges of lunar exploration, even

5:02 Speaker 1: as we develop increasingly sophisticated technology, Each mission, whether successful

5:07 Speaker 1: or not, provides valuable lessons that will help improve future

5:10 Speaker 1: attempts at exploring our celestial neighbor. All Right, this next

5:15 Speaker 1: story just might blow your mind, so to speak. The

5:18 Speaker 1: James Webb Space Telescope continues to reshape our understanding of

5:22 Speaker 1: the Cosmos, and its latest discovery might be its most

5:26 Speaker 1: mind bending yet. Recent observations have revealed something extraordinary about

5:30 Speaker 1: the rotation of galaxies in the early universe, a pattern

5:34 Speaker 1: that could suggest our entire universe exists within a black hole.

5:38 Speaker 1: And yes, you heard that right. During the James Webb

5:41 Speaker 1: Space Telescope Advanced Deep Extragalactic Survey, scientists observed two hundred

5:46 Speaker 1: and sixty three distant galaxies and found a striking pattern.

5:50 Speaker 1: Rather than seeing random rotation directions as expected, approximately two

5:54 Speaker 1: thirds of these galaxies are spinning clockwise, while the remaining

5:57 Speaker 1: third rotates counterclockwise. In a universe governed by random chance,

6:02 Speaker 1: we'd expect to see an even split between rotation directions.

6:07 Speaker 1: This coordinated cosmic dance raises profound questions about the nature

6:10 Speaker 1: of our universe. According to doctor Leor Shamir, who led

6:14 Speaker 1: the research team, there are two possible explanations for this phenomenon.

6:19 Speaker 1: The first and most intriguing suggestion is that our universe

6:22 Speaker 1: was born rotating, an idea that aligns with theories of

6:26 Speaker 1: black hole cosmology. This theory proposes that what we observe

6:30 Speaker 1: as our universe might actually be the interior of a

6:32 Speaker 1: black hole within a larger parent universe. Even more fascinating

6:36 Speaker 1: is the possibility that every black hole in our universe

6:38 Speaker 1: could be a gateway to another universe, though we could

6:41 Speaker 1: never observe these other realms directly due to the nature

6:45 Speaker 1: of black hole's event horizons. Polish physicist Nikodem Paplowski suggests

6:50 Speaker 1: that when black holes form from collapsing stars, the extreme

6:54 Speaker 1: conditions prevent matter from compressing indefinitely into a singularity. Instead,

6:59 Speaker 1: the matter, which is a state of incredible density, before

7:02 Speaker 1: bouncing back like a compressed spring, potentially creating a new,

7:06 Speaker 1: expanding universe, much like what we observe as our Big Bang.

7:10 Speaker 1: If our universe did indeed form inside a rotating black hole,

7:14 Speaker 1: it would inherit that rotation, which could explain the preferred

7:18 Speaker 1: direction of galaxy rotation we're now observing. This axis of

7:21 Speaker 1: rotation would be passed down from the parent universe's black hole,

7:25 Speaker 1: influencing the formation and movement of galaxies throughout our cosmic neighborhood. However,

7:31 Speaker 1: scientists are also considering a more mundane explanation that our

7:35 Speaker 1: own galaxies rotation might be affecting these observations, though previously

7:40 Speaker 1: this was thought to be too slight to matter. If

7:43 Speaker 1: this turns out to be the case, it could require

7:46 Speaker 1: a significant recalibration of how we measure distances in the

7:50 Speaker 1: deep universe, potentially resolving several other cosmological puzzles in the process.

7:56 Speaker 1: In other astronomy news today, in a remarkable breakthrough for

8:00 Speaker 1: astronomical research, scientists at the Max Plank Institute for Astronomy

8:04 Speaker 1: have created the most detailed three dimensional map ever made

8:07 Speaker 1: of cosmic dust in our Milky Way galaxy. This groundbreaking

8:11 Speaker 1: achievement utilized data from an astounding one hundred thirty million

8:14 Speaker 1: stellar spectra, combining information from both the European Space Agency's

8:18 Speaker 1: GUY emission and the Laymost Spectral Survey. Think of cosmic

8:22 Speaker 1: dust as nature's cosmic filter. It affects how we see

8:25 Speaker 1: everything in space, making distant objects appear both redder and

8:29 Speaker 1: dimmer than they actually are. It's like trying to look

8:32 Speaker 1: through a slightly dirty window into the vast expanse of space.

8:36 Speaker 1: Until now, astronomers have had to make do with relatively

8:38 Speaker 1: limited information about how this dust is distributed throughout our galaxy.

8:44 Speaker 1: The new map was created using innovative machine learning techniques

8:47 Speaker 1: to analyze the way starlight interacts with dust particles. By

8:51 Speaker 1: studying how dust affects light at different wavelengths, researchers can

8:55 Speaker 1: determine not just where the dust is, but also its

8:58 Speaker 1: composition and properties. This level of detail far surpasses previous efforts,

9:04 Speaker 1: which only included about a million measurements, but the study

9:07 Speaker 1: revealed something unexpected. Conventional wisdom suggested that in regions with

9:12 Speaker 1: higher dust density, the dust's effects on light should become

9:16 Speaker 1: more uniform across different wavelengths. Instead, the team found that

9:21 Speaker 1: in areas of medium density, shorter wavelengths of light are

9:25 Speaker 1: actually absorbed much more effectively than longer ones, a finding

9:29 Speaker 1: that challenges our current understanding of how cosmic dust behaves.

9:33 Speaker 1: This discovery has led researchers to propose an intriguing possibility.

9:37 Speaker 1: The unusual absorption patterns might be caused by complex molecules

9:41 Speaker 1: called polycyclic aromatic hydrocarbons PAHs. These molecules are the most

9:47 Speaker 1: common type of hydrocarbon in interstellar space and may have

9:50 Speaker 1: played a crucial role in the development of life itself.

9:53 Speaker 1: This new dust map isn't just an academic achievement. It's

9:56 Speaker 1: a practical tool that will help astronomers make more accurate

9:59 Speaker 1: O observations of distant objects. By knowing exactly how much

10:03 Speaker 1: dust lies between us and our astronomical targets, we can

10:07 Speaker 1: better understand what we're actually seeing when we look out

10:10 Speaker 1: into the cosmos. It's like finally having a clear understanding

10:14 Speaker 1: of how dirty that window really is, allowing us to

10:17 Speaker 1: see the universe more clearly than ever before. That's a

10:21 Speaker 1: wrap for today's episode of Astronomy Daily. I want to
