S03E189: Debris Dilemmas, Cosmic Espionage, and Black Hole Ballet

0:00 Speaker 1: Welcome to Astronomy Daily, your source for the latest space

0:02 Speaker 1: and astronomy news. I'm your host, Anna, and today we'll

0:06 Speaker 1: be covering a range of exciting topics, from space debris

0:08 Speaker 1: to black holes, a spy story, and even space tourism.

0:11 Speaker 1: Get ready for a cosmic journey through the latest discoveries

0:14 Speaker 1: and developments in the world of space exploration. Let's kick

0:18 Speaker 1: things off with one of the biggest problems facing the

0:20 Speaker 1: space industry today, and fortunately steps are being taken to

0:24 Speaker 1: address the problem. The European Space Agency is taking significant

0:27 Speaker 1: steps to address the growing issue of space debris with

0:30 Speaker 1: their innovative Zero Debris Charter. This initiative, launched in November

0:34 Speaker 1: twenty twenty three, aims to boost international cooperation in solving

0:38 Speaker 1: Earth's escalating space junk problem. The charter has gained impressive traction,

0:43 Speaker 1: with over one hundred signatories joining the cause. At a

0:46 Speaker 1: recent ceremony during the International Astronautical Congress in Milan, twenty

0:51 Speaker 1: four new partners signed on, including New Zealand and Mexico,

0:55 Speaker 1: the first countries outside Europe to do so. What makes

0:58 Speaker 1: this charter unique is its voluntary names. It's not a

1:01 Speaker 1: regulatory document, but rather a collaborative effort within the global

1:04 Speaker 1: space community. The charter outlines goals and guiding principles which

1:08 Speaker 1: will be developed into actionable and measurable targets. These principles

1:13 Speaker 1: include preventing intentional debris creation, anticipating and mitigating adverse effects,

1:19 Speaker 1: and promoting constant efforts to understand the problem. The charter

1:23 Speaker 1: also advocates for timely removal of spacecraft from orbit at

1:26 Speaker 1: the end of their missions and safe re entry practices.

1:30 Speaker 1: With an estimated million plus pieces of debris larger than

1:33 Speaker 1: a centimeter orbiting Earth, this initiative couldn't be more timely.

1:37 Speaker 1: It's a crucial step towards ensuring that space remains clean

1:40 Speaker 1: and safe for future generations and ongoing space operations.

1:45 Speaker 2: Next up.

1:46 Speaker 1: This sounds like a plot from a James Bond movie,

1:48 Speaker 1: but it's a real concern. In a recent development, China

1:51 Speaker 1: has raised concerns about foreign espionage targeting their space program.

1:54 Speaker 1: The Chinese government claims that foreign spies are attempting to

1:57 Speaker 1: steal secrets related to their space initiatives. This revelation highlights

2:01 Speaker 1: the growing tensions in the realm of space exploration and technology.

2:05 Speaker 1: While details are limited, this accusation underscores the competitive nature

2:09 Speaker 1: of space programs worldwide. It also raises questions about international

2:12 Speaker 1: cooperation and transparency in space related activities. As countries like

2:17 Speaker 1: China continue to advance their space capabilities, the potential for

2:20 Speaker 1: increased suspicion and security measures could impact global space relations.

2:25 Speaker 1: This situation serves as a reminder of the delicate balance

2:28 Speaker 1: between national interests and the collaborative spirit that has traditionally

2:32 Speaker 1: characterized space exploration. As we move forward, it will be

2:36 Speaker 1: crucial to monitor how these concerns shape future international space

2:40 Speaker 1: partnerships and information sharing. Next up, something making headlines in

2:45 Speaker 1: the astronomy world. In a groundbreaking discovery, astronomers have identified

2:49 Speaker 1: a unique triple system featuring a black hole with two

2:53 Speaker 1: orbiting stars. This remarkable find, described in a recent paper

2:57 Speaker 1: published in Nature, centers around V four hundred four signy,

3:01 Speaker 1: a black hole located about eight thousand light years from Earth.

3:05 Speaker 1: What makes this system particularly intriguing is its configuration. The

3:08 Speaker 1: first star, orbits V four hundred four signa every six

3:12 Speaker 1: point five days, so close that it's actually shedding material

3:15 Speaker 1: into the black hole's gravitational grasp. But it's the second

3:19 Speaker 1: star that's caught scientist's attention. This outer star is incredibly

3:23 Speaker 1: distant from the black hole, orbiting once every seventy thousand

3:26 Speaker 1: years at a distance one hundred times that between Pluto

3:30 Speaker 1: and our Sun. This discovery challenges our understanding of black

3:34 Speaker 1: hole formation. Typically, we believe black holes form from violent

3:37 Speaker 1: stellar explosions, which should disperse nearby objects. However, the presence

3:41 Speaker 1: of this distant star suggests a gentler formation process. Computer

3:46 Speaker 1: simulations indicate that the most likely scenario is a direct collapse,

3:51 Speaker 1: where the star that became the black hole simply caved

3:53 Speaker 1: in on itself without a dramatic explosion. This method would

3:57 Speaker 1: have allowed the distant star to remain gravitational bound to

4:00 Speaker 1: the system. This triple system not only provides new insights

4:04 Speaker 1: into black hole formation, but also helps astronomers determine the

4:07 Speaker 1: age of V four hundred four signy, estimated to be

4:11 Speaker 1: about four billion years old. As we continue to study

4:14 Speaker 1: this fascinating cosmic dance, we're sure to uncover more secrets

4:17 Speaker 1: about the nature of black holes and the evolution of

4:20 Speaker 1: our universe. Now, another story featuring the ESA. The European

4:25 Speaker 1: Space Agency's EUCLID mission has just released an incredible two

4:28 Speaker 1: hundred eight gigapixel mosaic of the Southern Sky, and it's

4:31 Speaker 1: a site to behold. This massive image covers an area

4:35 Speaker 1: more than five hundred times larger than a full moon,

4:37 Speaker 1: giving us a tantalizing glimpse into the vastness of our universe.

4:41 Speaker 1: But EUCLID isn't just about pretty pictures. This space telescope

4:44 Speaker 1: has a crucial mission to help us understand the mysterious

4:47 Speaker 1: force known as dark energy. Scientists believe dark energy is

4:51 Speaker 1: responsible for the accelerating expansion of our universe, but we

4:55 Speaker 1: still know very little about it. To tackle this cosmic mystery,

4:58 Speaker 1: EUCLID will map billions of galaxies across ten billion light

5:01 Speaker 1: years of space. This preliminary data release is just a

5:04 Speaker 1: small taste of what's to come. Over the next six years,

5:07 Speaker 1: EUCLID will survey an area thousands of times larger, creating

5:11 Speaker 1: the most extensive three D map of the cosmos ever constructed.

5:15 Speaker 1: What's truly remarkable is that this initial mosaic, representing just

5:20 Speaker 1: one percent of euclid's total survey area, already contains around

5:24 Speaker 1: one hundred million.

5:25 Speaker 2: Stars and galaxies.

5:27 Speaker 1: Of these, about fourteen million galaxies could be used to

5:30 Speaker 1: study dark energy's influence on the universe. As EUCLID continues

5:33 Speaker 1: its mission, it will provide unprecedented insights into the structure

5:38 Speaker 1: and evolution of our universe, potentially revolutionizing our understanding of

5:42 Speaker 1: cosmology and the fundamental forces that shape our reality. In

5:47 Speaker 1: a recent development, NASA has put the brakes on plans

5:50 Speaker 1: to reduce operations of two major space telescopes as a

5:53 Speaker 1: cost cutting measure.

5:54 Speaker 2: The decision regarding budget.

5:56 Speaker 1: Cuts for the Chandra X Ray Observatory and Hubble Space

5:58 Speaker 1: Telescope has been deferred until after the agency receives its

6:02 Speaker 1: final appropriations for fiscal year twenty twenty five. This delay

6:06 Speaker 1: comes as a relief to many in the scientific community

6:09 Speaker 1: who were concerned about the potential impact on these vital instruments.

6:13 Speaker 1: The proposed cuts were significant, with Chandra facing a forty

6:16 Speaker 1: percent reduction in its operating budget and Hubble looking at

6:19 Speaker 1: a ten percent cut. The delay allows for more time

6:22 Speaker 1: to assess the situation and potentially find alternative solutions. It

6:26 Speaker 1: also highlights the ongoing challenges of balancing a diverse portfolio

6:29 Speaker 1: of missions within budget constraints. As we await the final

6:33 Speaker 1: budget decisions, the scientific community remains hopeful that these iconic

6:38 Speaker 1: telescopes will continue their groundbreaking work in unraveling the mysteries

6:42 Speaker 1: of our universe. Next, let's turn our attention to another

6:47 Speaker 1: big scientific discovery from way out there. In a groundbreaking discovery,

6:51 Speaker 1: astronomers have found one of the largest carbon based molecules

6:54 Speaker 1: ever detected in deep space. The molecule, called Pirini, was

6:59 Speaker 1: located within the Chorous Molecular Cloud about four hundred and

7:02 Speaker 1: thirty light years from Earth. This finding is significant because

7:05 Speaker 1: it provides crucial clues that could help solve a long

7:09 Speaker 1: standing mystery in astrochemistry, the origin of carbon, the building

7:14 Speaker 1: block of life. Pyrene is a polycyclic aromatic hydrocarbon or PAH,

7:18 Speaker 1: made up of four fused planar rings of carbon. These

7:21 Speaker 1: molecules are among the most abundant complex molecules in the

7:24 Speaker 1: visible universe, and are thought to make up roughly twenty

7:27 Speaker 1: percent of the carbon found in space. What's particularly intriguing

7:31 Speaker 1: about this discovery is that purine was found in an

7:33 Speaker 1: extremely cold environment, with temperatures as low as ten kelvin.

7:37 Speaker 1: This challenges our understanding of how these molecules form, as

7:40 Speaker 1: on Earth, they're typically created through high temperature processes. The

7:45 Speaker 1: presence of pyrene in the birthplace of our Solar system

7:48 Speaker 1: provides a direct link between the early molecular clouds and

7:51 Speaker 1: the composition of celestial bodies like asteroids. This connection offers

7:56 Speaker 1: valuable insights into the chemical evolution of our cosmic neighborhood

7:59 Speaker 1: and potent meally the origins of life itself. Finally, today

8:04 Speaker 1: it looks like we have another space tourism provider on

8:06 Speaker 1: the horizon. In an exciting development for space enthusiasts, a

8:10 Speaker 1: Chinese company called Jiangsu Deep Blue Aerospace Technology has announced

8:15 Speaker 1: its now taking pre orders for suborbital space tourism flights,

8:19 Speaker 1: with the first launch planned for twenty twenty seven. The

8:22 Speaker 1: company's CEO, Hua Yang shared details of their commercial spacecraft

8:26 Speaker 1: during a recent live broadcast. Deep Blue Aerospace's plans include

8:30 Speaker 1: a reusable rocket called Nebula one, which bears some resemblance

8:33 Speaker 1: to SpaceX's Falcon nine. Their spacecraft is designed to carry

8:37 Speaker 1: six passengers to an altitude of one hundred kilometers, crossing

8:41 Speaker 1: the Carmen Line, the official boundary of space. Passengers will

8:44 Speaker 1: experience about five minutes of weightlessness during the twelve minute flight.

8:48 Speaker 1: This move puts China in direct competition with established players

8:51 Speaker 1: in the space tourism market like Virgin Galactic, Blue Origin,

8:55 Speaker 1: and SpaceX. While these companies have already conducted successful flights,

9:00 Speaker 1: entry into the field could potentially make space tourism.

9:03 Speaker 2: More accessible globally.
