    The Rubin Observatory has detected thousands of new asteroids, including several that spin a lot faster than expected for typical rubble piles. The post Rubin Observatory Detects Record-Breaking Asteroids appeared first on Sky & Telescope.

    A two-stage, H3-24L rocket lit up the predawn skies over Tanegashima Space Center on the southern tip of Japan early on Tuesday, October 20th (3:41 p.m. EDT on October 19th), … The post Japan Launches the Martian Moons Exploration Mission appeared first on Sky & Telescope.

    Today’s impact of a spent Falcon 9 rocket stage on the Moon may sound dramatic, but it is neither the first human-made object to strike our natural satellite nor the largest.

  • 2026-10-30
    Ancient Martian meteorites are like time-capsules from the planet's past. They're delivered to us by impacts that launch them into space, where some of them find their way to Earth. One recently discovered meteorite found in the Sahara desert adds weight to the idea that Mars was once warm and ...

    Studying the interiors of planets is essential for understanding planetary formation, evolution, and their ability to potentially host life as we know it. To accomplish this, researchers use a combination of Earth as an analog, computer models, meteorites, and data collected from other planetary bodies for studying their interior compositions. ...

    Earth may not have needed comets and asteroids to deliver its water after it formed and cooled. Instead, water creation could have been part of the planet's formation process. New research explains how, and even shows that water creation could be a part of every rocky planet's formation.
  • 2026-10-28
    Perhaps the biggest mystery we face is life on Earth started. One hypothesis says that comets, which are known to carry important chemicals in abiogenesis, delivered these compounds to Earth, leading to the appearance of life. But new research concludes that that is highly unlikely.

  • 2026-10-30
    A researcher says the Taurid meteor shower could bring an increased risk of an airburst in 2026. But these Halloween fireballs are based on 2 big IFs. The post Could the Taurid meteors bring a risk of airbursts in 2026? first appeared on EarthSky.



  • 2026-10-30
    Most of us could spend our entire lives looking at the night sky and see very few changes. The moon becomes more or less illuminated, the planets drift placidly through the sky, satellites and the ISS intrude for a few moments at a time, and the bright, momentary streak of ...
  • 2026-10-27
    A Southwest Research Institute–led study used NASA's James Webb Space Telescope to examine ice grains streaming from interstellar comet 3I/ATLAS, just the third object from beyond our solar system ever identified. The observations point to tiny aggregates of water ice and dust, about a micron or smaller.
  • 2026-10-27
    The European Space Agency's Hera spacecraft for planetary defense has resolved its two target asteroids separately for the first time, revealing the binary nature of the Didymos system, currently some 197 million km (122 million miles) away from Earth.
  • 2026-10-27
    Over 1,645 Martian days, NASA's Perseverance Mars rover measured the fine and ultrafine Martian dust particles found clinging to samples of spacesuit materials that are carried aboard the rover, including particles small enough to penetrate the lungs and enter the bloodstream. The findings are published in the Proceedings of the ...
  • 2026-10-20
    The Orionids—one of two major meteor showers caused by remnants from Halley's Comet—will peak this week, though a large moon will dim visibility until after it sets late at night.
  • 2026-10-20
    On Oct. 16, 2021, NASA's Lucy spacecraft began its journey to the never-before-explored Jupiter Trojan asteroids with an early morning launch. Now less than a year away from the first-ever close-up of a Trojan, the Southwest Research Institute–led mission has already made several findings during its first five years.
  • 2026-10-18
    Japanese scientists are readying a mission to Mars' moons to retrieve samples that could help unlock the origins of the solar system and life on Earth, in what aims to be the first round trip to the Martian region.
  • 2026-10-18
    A Japanese space mission is about to launch towards Mars. But it will not land on the planet itself. Instead, the Martian Moons Exploration (MMX) mission will focus on Phobos, the bigger of Mars's two small moons.

  • 2026-10-29
    Scientists have uncovered seven surprising stages that space rocks go through as they hurtle toward Earth, revealing that melting and violent fragmentation, rather than simple evaporation, determine their fate. The discovery could help explain why meteorites scatter across the ground and how dangerous asteroids explode in Earth's atmosphere.
  • 2026-10-24
    Tiny samples from asteroid Bennu are rewriting scientists' understanding of how our Solar System formed. New evidence suggests that Bennu was born where material from the inner and outer Solar System mixed, with Jupiter playing a surprising role in shaping its formation.
  • 2026-10-21
    A new study tracking 13 astronauts suggests that the human heart may be surprisingly well equipped for a journey to Mars, especially with regular exercise during spaceflight. Researchers found that astronauts' hearts adapted to months of weightlessness and handled simulated Martian gravity without major problems, offering new hope for future ...
  • 2026-10-21
    NASA’s Perseverance rover has shattered a historic space exploration record, traveling farther across another world than any vehicle before it. Its advanced self-driving system helped it surpass Opportunity’s 28.06-mile record in just five and a half years, a feat that previously took nearly 15. Now, Perseverance is exploring some of ...
  • 2026-10-20
    NASA scientists have finally uncovered why asteroid Bennu loses heat so quickly despite being covered in massive boulders. Samples returned to Earth reveal that its rocks are filled with hidden cracks, solving a mystery that has puzzled researchers for years.

    Astronoms Karls Seigans reiz teicis, ka "mēs visi esam radušies no zvaigžņu putekļiem", un tas nav nekas pārspīlēts, jo dzīvības pamatā patiesi ir elementi, kuri radušies un "izsējušies" mežonīgajā zvaigžņu dzimšanas un bojāejas rezultātā, Latvijas Radio raidījumā "Zināmais nezināmajā" skaidroja ķīmiķis, astronomijas entuziasts Jānis Jaunbergs un astrofiziķis, Meteorītu muzeja vadītājs ...

    GADA METEORĪTS
    2020
    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!
