  • Lasers Can Melt Through Extraterrestrial Ice Efficiently
    2025-09-13
    Lasers aren’t just useful for entertaining cats or pointing out features of powerpoint slides. They can also drill holes on icy extraterrestrial bodies from comets to Mars polar caps. At least according to a new paper in Acta Astronautica by researchers at the Technical University of Dresden, who describe a ...
  • This Trio Of Robots Could Explore Lunar Caves
    2025-09-13
    Seeking refuge in caves is natural. Animals do it, and so did our ancestors. Future lunar astronauts may do the same when they visit the Moon. Lunar caves can provide protection from the harsh radiation that bathes the Moon, the wild temperature swings on its surface, and from meteorites that ...
  • Where Did The Interstellar Comet 3I/ATLAS Come From?
    2025-09-13
    When an interstellar object (ISO) travels through our inner Solar System, the immediate question is "Where did it come from?"

  • One Wrong Hit Could Send an Asteroid on a Collision Course with Earth
    2025-09-13
    It was a chilly night when I peered through my 10” Meade LX200 telescope from Norfolk in the UK! I wasn’t completely convinced it would appear nor even be visible but bang on the prediction, asteroid 2002 MN drifted by my field of view and I was amazed at how ...
  • The Gemini South Telescope Takes A Turn Imaging The Interstellar Comet 3I/ATLAS
    2025-09-13
    Interstellar comets are rare, and astronomers don't like to miss an opportunity to observe one. Now the Gemini South Telescope has taken a turn at imaging Comet 3I/ATLAS, the visitor from another star system. The images help show that the comet's tail is growing as it approaches the Sun.
  • Tiny asteroid 2025 RJ2 makes close flyby of moon and Earth
    2025-09-15
    A tiny asteroid will make a close pass by Earth and an even closer pass by the moon on Monday and Tuesday. It poses no threat to us. The post Tiny asteroid 2025 RJ2 makes close flyby of moon and Earth first appeared on EarthSky.

    2025-09-15
    A new comet is visible not far from the setting sun. Comet SWAN25B is already bright, though its location will make it a challenge to observe. Finder map here! The post New comet SWAN25B already bright, but near sunset’s glow first appeared on EarthSky.
  • Asteroid tells secrets of Earth's 'far wetter' building blocks
    2025-09-15
    Tokyo (AFP) Sept 10, 2025 Earth's building blocks were "far wetter" than previously imagined, new analysis of tiny samples from a distant asteroid has suggested, overturning long-held assumptions about the early solar system. Research on a tiny portion of the 5.4 grams of rock and dust collected from the Ryugu ...
  • Clues to ancient Martian chemistry revealed by Perseverance rover
    2025-09-15
    Los Angeles CA (SPX) Sep 11, 2025 NASA's Perseverance rover has uncovered evidence of long-ago chemical processes while exploring Jezero Crater, giving scientists fresh insight into how minerals, water, and possibly organics interacted billions of years ago. A new Nature News and Views article by SETI Institute Senior Research Scientist Janice ...
  • Perseverance Rover Captures Elusive Martian Aurora for a Second Time
    2025-09-15
    Scientists using NASA’s Perseverance rover have captured visible green auroras on Mars and developed tools to predict them. Planetary scientists say they can now forecast when a green aurora will appear in Mars’s night sky, supported by new images. NASA’s Perseverance rover recorded the first visible-light aurora from the Martian ...
  • The Tiny Cosmic “Keyholes” That Could Send Asteroids Back to Earth
    2025-09-15
    Deflecting an asteroid isn’t just a matter of smashing into it with a spacecraft. If the strike happens in the wrong place, it could nudge the space rock into a tiny gravitational “keyhole,” a hidden gateway that steers it back onto a collision course with Earth. Building on lessons from ...
  • NASA's Perseverance rover finds clues to ancient Mars chemistry and possible life
    2025-09-13
    Mars’ Jezero Crater holds signs of ancient water and strange mineral reactions, some linked with organic compounds. With Perseverance’s samples and AI-refined mineral maps, scientists are closing in on whether Mars once had the chemistry needed for life.
  • Life on Mars? NASA discovers potential biosignatures in Martian mudstones
    2025-09-11
    NASA’s Perseverance rover has discovered mudstones in Mars’ Jezero Crater that contain organic carbon and unusual textures hinting at possible biosignatures. These findings suggest that ancient Martian environments may have supported chemical processes similar to those on Earth, where microbial life thrives. While the team stresses they have not discovered ...
  • Hit the wrong spot and an asteroid returns on a collision course
    2025-09-09
    Scientists caution that asteroid deflection must be precise, as striking the wrong spot risks sending it through a gravitational keyhole that sets up a future collision with Earth. Using lessons from NASA’s DART mission, researchers are developing probability maps to guide safer impact strategies.
  • MIT scientists uncover shocking origin of the moon’s magnetic scars
    2025-09-06
    For decades, scientists have puzzled over why lunar rocks show signs of strong magnetism when the moon itself has no global magnetic field today. New simulations suggest the answer may lie in a powerful asteroid impact billions of years ago.
  • NASA’s SPHEREx Captures Comet 3I/ATLAS, a Visitor From Beyond the Solar System
    2025-09-02
    NASA’s SPHEREx joined Webb and Hubble in studying interstellar comet 3I/ATLAS, gathering data on its size, chemistry, and physical traits. While harmless to Earth, the comet provides scientists a rare opportunity to learn more about solar system wanderers.
  • NASA’s Webb Space Telescope Reveals Secrets of Interstellar Comet 3I/ATLAS
    2025-09-02
    Webb, Hubble, and SPHEREx are joining forces to study the interstellar comet 3I/ATLAS, revealing details about its structure and chemistry. The comet isn’t dangerous, but it’s offering scientists a rare chance to explore material from outside our solar system.
  • Astronomers stunned as James Webb finds a planet nursery flooded with carbon dioxide
    2025-08-31
    Astronomers using the James Webb Space Telescope have uncovered a planet-forming disk shockingly rich in carbon dioxide but nearly devoid of water, upending traditional theories of planetary chemistry. Found in a harsh star-forming region flooded with radiation, the discovery hints that cosmic environments may drastically reshape the ingredients that shape ...

GADA METEORĪTS
2025
Meteoriti.LV vietne tiks pakāpeniski papildināta ar plašu pamatinformāciju par meteorītiku un ar to saistitām astronomijas nozarēm. Uzzināsiet, vai "meteorīti dabā sastopami retāk par dimantiem", cik tie ir veci un kāda ir to izcelsme. Atradīsiet atbildes uz jautājumiem: Vai meteorīti ir bīstami? Kādi meteorīti atrodami Latvijā un kur tos var apskatīt? Vai Latvijā ir vērts meklēt meteorītus? Ko meteorītu izpēte pastāsta mums par Zemes un Saules sistēmas izcelšanos? Ceram, ka tas radīs vēlmi arī jums pašiem novērot Zemes kosmiskos viesus - meteorus, un, varbūt, pat kļūt par īstiem meteorītu medniekiem!
Veiksmīgu novērošanu!
