| | 2. How NASA's Perseverance is helping prepare astronauts for MarsПт, 28 мар[-/+]Категория(?) | NASA's Perseverance rover landed on Mars in 2021 to search for signs of ancient microbial life and to help scientists understand the planet's climate and geography. But another key objective is to pave the way for human exploration of Mars, and as part of that effort, the rover carries a set of five spacesuit material samples. Now, after those samples have endured four years of exposure on Mars' dusty, radiation-soaked surface, scientists are beginning the next phase of studying them. Медиа: image / jpg | ↑ |
3. Could Venus host life? The Venus life equation can help us find outПт, 28 мар[-/+]Категория(?) | What drives us to send probes throughout the solar system and rovers and landers to Mars? It's not cheap, and it's not easy. It's because we live inside a big, natural puzzle, and we want to understand it. That's one reason. But the main reason for space exploration is to search for life beyond Earth. That our planet could be the only planet to host life is a disquieting thought. Медиа: image / jpg | ↑ |
4. The future of studying exoVenuses looks brightПт, 28 мар[-/+]Категория(?) | What can Venus-like exoplanets, also known as exoVenuses, teach us about our own solar system and potentially finding life beyond Earth, and how can the planned Habitable Worlds Observatory (HWO) provide these insights?

6. NOAA's GOES-19 satellite releases new coronagraph data to publicПт, 28 мар[-/+]Категория(?) | Near real-time preliminary data from NOAA's first Compact Coronagraph (CCOR-1), a powerful solar telescope onboard the GOES-19 satellite, are now publicly accessible. GOES-19, launched in June 2024, began providing the new data through the Space Weather Prediction Center (SWPC) website as of February 25, 2025, and from the National Centers for Environmental Information (NCEI) archive starting March 7, 2025.

9. Video: Watch wind whirl from the sunЧт, 27 мар[-/+]Категория(?) | Aside from sunlight, the sun sends out a gusty stream of particles called the solar wind. The ESA-led Solar Orbiter mission is the first to capture on camera this wind flying out from the sun in a twisting, whirling motion. The solar wind particles spiral outward as if caught in a cyclone that extends millions of kilometers from the sun. Медиа: image / jpg | ↑ |
11. One day we might seed the universe with life. But should we?Чт, 27 мар[-/+]Категория(?) | Suppose humanity was faced with an extinction-level event. Not just high odds, but certain-sure. A nearby supernova will explode and irradiate all life, a black hole will engulf the Earth, a Mars-sized interstellar asteroid with our name on it. A cataclysm that will end all life on Earth.

15. Small star, mighty flares: ALMA shares new view of Proxima CentauriЧт, 27 мар[-/+]Категория(?) | At a distance of just over four light years, Proxima Centauri is our nearest stellar neighbor and is known to be a very active M dwarf star. Its flare activity has been well-known to astronomers using visible wavelengths of light, but a new study using observations with the Atacama Large Millimeter/submillimeter Array (ALMA) array highlights this star's extreme activity in radio and millimeter wavelengths, offering exciting insights about the particle nature of these flares as well as potential impacts to the livability of its terrestrial, habitable-zone planets.

17. Four new gamma-ray millisecond pulsars discoveredЧт, 27 мар[-/+]Категория(?) | An international team of astronomers reports the detection of four new gamma-ray millisecond pulsars using the Murriyang radio telescope at the Parkes Observatory in Australia. The discovery was detailed in a research paper published March 16 on the arXiv preprint server. Медиа: image / jpg | ↑ |
21. New insights into little red dots—an early phase of black hole growthСр, 26 мар[-/+]Категория(?) | The James Webb Space Telescope has given us a view of the earliest moments of galaxy formation in the universe. It's also revealed a few surprises. One of these is the appearance of small, highly redshifted objects nicknamed "little red dots (LRDs)." We aren't entirely sure what they are, but a new study points to an answer. Медиа: image / jpg | ↑ |
24. X-ray observations reveal dynamic features of galaxy cluster PLCKG287Ср, 26 мар[-/+]Категория(?) | Using NASA's Chandra X-ray observatory, astronomers have observed a massive and hot galaxy cluster known as PLCKG287.0+32.9 (or PLCKG287 for short). Results of the observational campaign, presented March 17 on the arXiv pre-print server, deliver important insights into the morphological and thermodynamical properties of this cluster.

25. Protoplanetary disks are much smaller than previously thought, new study findsСр, 26 мар[-/+]Категория(?) | Many protoplanetary disks in which new planets are formed are much smaller than thought. Using the Atacama Large Millimeter/submillimeter Array (ALMA) scientists of the Leiden Observatory (the Netherlands) looked at 73 protoplanetary disks in the Lupus region. They found that many young stars host modest disks of gas and dust, some as small as 1.2 astronomical units. The research, accepted for publication in Astronomy & Astrophysics, establishes an important link between observed protoplanetary disks and exoplanets. Медиа: image / jpg | ↑ |
26. Image: Atomic Clock Ensemble in Space: Time to get readyВт, 25 мар[-/+]Категория(?) | ESA's Atomic Clock Ensemble in Space (ACES) has arrived at NASA's Kennedy Space Center in Florida, United States. This cutting-edge European experiment will test fundamental physics from the outside of ESA's Columbus module on the International Space Station, measuring time from orbit with unprecedented precision.

29. Fluorescent caves could explain how life persists in extraterrestrial environmentsВт, 25 мар[-/+]Категория(?) | Deep below Earth's surface, rock and mineral formations lay hidden with a secret brilliance. Under a black light, the chemicals fossilized within shine in brilliant hues of pink, blue and green. Scientists are using these fluorescent features to understand how the caves formed and how life is supported in extreme environments, which may reveal how life could persist in faraway places, like Jupiter's icy moon Europa.
