Категория^(?)

A research team led by Prof. Di Kaichang from the Aerospace Information Research Institute (AIR) of the Chinese Academy of Sciences has developed an innovative method to enhance the study of lobate scarps—small reverse fault landforms thought to reflect ancient tectonic activity on the moon.

4. How many rogue planets are in the Milky Way? The Roman Space Telescope will give us an answer16:26[-/+]

Категория^(?)

Over the past decade or so, astronomers have speculated about the characteristics of rogue planets in the Milky Way galaxy. These "free-floating" worlds don't orbit stars, but instead roam the spaceways. They're hard to spot with current technology, but the upcoming Nancy Grace Roman Space Telescope (Roman) will be a perfect instrument to find them and give insights into the history and features they may have in common with solar system worlds.

5. Quasars don't last long—so how do they get so massive?15:47[-/+]

Категория^(?)

Quasars represent some of the most luminous and energetic phenomena in the universe. These distant powerhouses are driven by supermassive black holes—colossal gravitational engines with masses millions to billions of times that of our sun—which actively devour surrounding matter at incredible rates.

6. NASA telescopes tune into a black hole prelude and fugueЧт, 08 мая[-/+]

Категория^(?)

NASA has released three new pieces of cosmic sound that are associated with the densest and darkest members of our universe: black holes. These scientific productions are sonifications—or translations into sound—of data collected by NASA telescopes in space, including the Chandra X-ray Observatory, James Webb Space Telescope, and Imaging X-ray Polarimetry Explorer (IXPE).

7. Hubble pinpoints roaming massive black holeЧт, 08 мая[-/+]

Категория^(?)

Like a scene out of a sci-fi movie, astronomers using NASA telescopes have found "Space Jaws." Lurking 600 million light-years away, within the inky black depths between stars, there is an invisible monster gulping down any wayward star that plummets toward it. The sneaky black hole betrayed its presence in a newly identified tidal disruption event (TDE) where a hapless star was ripped apart and swallowed in a spectacular burst of radiation.

8. Webb visualization reveals 3D structure of Cosmic CliffsЧт, 08 мая[-/+]

Категория^(?)

In July 2022, NASA's James Webb Space Telescope made its public debut with a series of breathtaking images. Among them was an ethereal landscape nicknamed the Cosmic Cliffs. This glittering realm of star birth is the subject of a new 3D visualization derived from the Webb data. The visualization, created by NASA's Universe of Learning and titled "Exploring the Cosmic Cliffs in 3D," breathes new life into an iconic Webb image.

10. DNA-like molecule may survive Venus-like cloud conditionsЧт, 08 мая[-/+]

Категория^(?)

Punishing conditions in the clouds of Venus could be home to a DNA-like molecule capable of forming genes in life very different to that on Earth, according to a new study.

11. There's a chorus of gravitational waves coming from the core of the Milky Way. Will we hear them?Чт, 08 мая[-/+]

Категория^(?)

There is a supermassive black hole at the center of our galaxy, and it's not alone. There is also likely a forest of binary black holes, neutron stars, and white dwarfs. All of these emit gravitational waves as they gradually spiral ever closer together. These gravitational waves are too faint for us to detect at the moment, but future observatories will be able to observe them. This poses an interesting astronomical challenge.

12. A single impact could leave a giant planet ringing for millions of yearsЧт, 08 мая[-/+]

Категория^(?)

To understand how chaotic the early solar system was, we need only gaze at the moon. Its cratered surface bears the scars of multitudes of collisions. The early solar system was like a debris field where objects smashed into each other in cascades of collisions. The same must be true in all young solar systems, and in a new paper, researchers describe how they simulated a collision between two massive planets to see what would happen.

13. X-ray source AX J145732–5901 is a cluster of galaxies, observations suggestЧт, 08 мая[-/+]

Категория^(?)

Japanese astronomers have presented new results of observations that suggest an unidentified X-ray source designated AX J145732–5901 is a cluster of galaxies behind the galactic plane. The findings are detailed in a research paper published April 30 on the arXiv preprint server.

15. Spacecraft can 'brake' in space using drag – advancing craft agility, space safety and planetary missionsСр, 07 мая[-/+]

Категория^(?)

When you put your hand out the window of a moving car, you feel a force pushing against you called drag. This force opposes a moving vehicle, and it's part of the reason why your car naturally slows to a stop if you take your foot off the gas pedal. But drag doesn't just slow down cars.

16. Shortwave radiation sheds light on how Earth worksСр, 07 мая[-/+]

Категория^(?)

When our planet and the incoming sunlight align just right, stunning phenomena such as rainbows and halos can occur. More often, sunlight—or shortwave radiation—interacts with the Earth in subtle but curious ways.

17. Free floating binary planets may not survive for longСр, 07 мая[-/+]

Категория^(?)

The JWST continues to live up to its promise by revealing things hidden from other telescopes. One of its lesser-known observations concerns free-floating planets (FFP). FFPs have no gravitational tether to any star and are difficult to detect because they emit so little light. When the JWST detected 42 of them in the Orion Nebula Cluster, it gave astronomers an opportunity to study them more closely.

Категория^(?)

Picture this: a small audience is quietly ushered into a darkened room. They gasp in awe, as a brilliant night sky shines above. They wonder—as many after them will do—what trickery has made the roof above their heads disappear?

What new technologies or methods can be developed for more efficient in-situ planetary subsurface analyses? This is what a recent study presented at the 56th Lunar and Planetary Science Conference hopes to address as a team of researchers investigated how a novel instrument called OptiDrill could fill existing technological voids regarding the sampling and collection of regolith (top dust layer) and subsurface samples on a myriad of planetary bodies throughout the solar system.
