    Everyone’s favorite interstellar comet posed for one more portrait recently. The European Space Agency’s XMM-Newton mission nabbed 3I/ATLAS on December 3rd from about 283 million kilometers distant. This comes as the comet is set to make its closest passage versus Earth this coming Friday, on December 19th.

    Los Angeles CA (SPX) Dec 18, 2025 After nearly five years operating inside Mars Jezero Crater, NASA's Perseverance rover has logged almost 25 miles (40 kilometers) of driving while engineers certify that its mobility hardware and other subsystems can keep working for many more years. Built and operated by NASA's Jet ...

    Mars is a dusty planet dominated by vast, dry deserts, with no easily accessible sources of liquid water. Much like on Earth, dust is lifted from Mars's surface by wind and rotating air columns, transported through the atmosphere, and deposited back onto the planet's surface via sedimentation. The Martian dust ...

    Much remains to be known about the chemical composition of small asteroids. Their potential to harbor valuable metals, materials from the early solar system, and the possibility of obtaining a geochemical record of their parent bodies makes them promising candidates for future use of space resources.

    Researchers at Auburn University have identified a distinctive ultraviolet signature of water in the interstellar comet known as 3I/ATLAS. For millions of years, a fragment of ice and dust drifted between the stars—like a sealed bottle cast into the cosmic ocean. This summer, that bottle finally washed ashore in our ...

    SPHERE’s detailed images of dusty rings around young stars offer a rare glimpse into the hidden machinery of planet formation. These bright arcs and faint clouds reveal where tiny planet-building bodies collide, break apart, and reshape their systems. Some disks contain sharp edges or unusual patterns that hint at massive ...

    Scientists have discovered that moonquakes, not meteoroids, are responsible for shifting terrain near the Apollo 17 landing site. Their analysis points to a still-active fault that has been generating quakes for millions of years. While the danger to short missions is low, long-term lunar bases could face increasing risk. The ...

    For thirty years, SOHO has watched the Sun from a stable perch in space, revealing the inner workings of our star and surviving crises that nearly ended the mission. Its long-term observations uncovered a single global plasma conveyor belt inside the Sun, detailed how solar brightness subtly shifts over the ...

    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!
