  • Astronomers Pinpoint 3I/ATLAS's Path Based on Data from Mars
    2025-11-27
    Since comet 3I/ATLAS, the third known interstellar object, was discovered on 1 July 2025, astronomers worldwide have worked to predict its trajectory. ESA has now improved the comet’s predicted location by a factor of 10, thanks to the innovative use of observation data from our ExoMars Trace Gas Orbiter (TGO) ...
  • Hong Kong's Mission to Watch the Moon Get Bombarded
    2025-11-27
    In 2028, Hong Kong will launch its first dedicated lunar orbiter not to study craters or map minerals, but to monitor something far more urgent, the constant barrage of meteoroids slamming into the Moon's surface at thousands of kilometres per hour. As China prepares to build a permanent lunar research ...
  • What Seven Decades of Hunting for Aliens Tells Us
    2025-11-26
    Seven billion year old meteorites carrying DNA building blocks. Frozen water on Mars. Amino acids floating in interstellar dust clouds. After seventy years of searching, we've found the ingredients for life scattered throughout the universe but have we found life itself? A new review examines every major claim of extraterrestrial ...
  • Tally of near-Earth asteroids passes 40,000
    2025-11-27
    Astronomers announced in November 2025 they've now discovered over 40,000 near-Earth asteroids. What risks do these pose to Earth? The post Tally of near-Earth asteroids passes 40,000 first appeared on EarthSky.
  • What seven decades of hunting for aliens tells us
    2025-11-29
    Since the 1950s, humanity has been searching for extraterrestrial life with increasingly sophisticated tools. But after decades of space probes, meteorite analysis, radio telescopes, and UFO investigations, what have we actually found? A new piece of analysis by a team led by Seyed Sina Seyedpour Layalestani from the Islamic Azad ...
  • From the volcanic crater to the lab: Extremophiles offer a lesson in survival
    2025-11-29
    "Adapt or perish, now as ever, is nature's inexorable imperative," wrote H. G. Wells. This principle—that survival requires change—was mastered billions of years ago by single-celled organisms living in extreme heat. Over the past few decades, studies of these organisms' adaptive mechanisms have yielded revolutionary technologies—from rapid DNA replication (PCR) ...
  • Asteroid loaded with amino acids offers new clues about the origin of life on Earth
    2025-11-29
    One of the most elegant theories about the origins of life on our planet is that it was kick-started by a delivery from outer space. This idea suggests that prebiotic molecules—the building blocks of life—were transported here by asteroids or other celestial bodies. While these molecules have been found in ...

  • Meteorite samples are time capsules from the early solar system
    2025-11-27
    When a meteor streaks across the sky, it's not just beautiful. It's nature's way of delivering a time capsule to Earth. Contained within are hints about the very beginning of the solar system and how planets, including our own, formed.
  • Meteorite crater hosts methane-making microbes—a clue to life on Mars?
    2025-11-26
    Scientists have discovered living microbes producing methane in the fractured rocks deep inside Sweden's Siljan impact crater, offering insights into Earth's earliest life and the search for life beyond our planet.
  • Finding 40,000 asteroids before they find us
    2025-11-25
    The number 40,000 might not sound particularly dramatic, but it represents humanity's growing catalog of near-Earth asteroids, rocky remnants from the solar system's violent birth that cross paths with our planet's orbit. We've come a long way since 1898, when astronomers discovered the first of these wanderers, an asteroid called ...
  • Scientists Discover Surprising Glacial Patterns Hidden on Mars
    2025-11-29
    New Mars Express images show grooves, ridges, and crater patterns carved by ancient glaciers. These icy flows once reached well into Mars’s mid-latitudes, far from the poles. Their presence reveals powerful climate shifts driven by changes in the planet’s tilt. Together, these features offer one of the clearest records of ...
  • New Mars images reveal hidden traces of a recent ice age
    2025-11-26
    Mars’s Coloe Fossae reveals a landscape shaped by ancient ice ages, with deep valleys, cratered terrain, and frozen debris flows preserved from a time when the planet’s climate dramatically shifted.
  • Scientists may have found the planet that made the Moon
    2025-11-23
    About 4.5 billion years ago, a colossal impact between the young Earth and a mysterious planetary body called Theia changed everything—reshaping Earth, forming the Moon, and scattering clues across space rocks. By examining subtle isotopic fingerprints in Earth and Moon samples, scientists have reconstructed Theia’s possible composition and birthplace.
  • Japanese spacecraft faces a massive challenge from a house-size asteroid
    2025-11-21
    New observations show that asteroid 1998 KY26 is a mere 11 meters across and spinning twice as fast as previously thought. The discovery adds complexity to Hayabusa2’s 2031 mission but also heightens scientific interest. The asteroid’s composition remains uncertain, making the encounter even more compelling. Insights from this work could ...
  • Scientists uncover a massive hidden crater in China that rewrites Earth’s recent history
    2025-11-14
    A massive, well-preserved impact crater has been uncovered in Guangdong, revealing the signature of a powerful meteorite strike during the Holocene. Measuring 900 meters across, it dwarfs other known craters from the same era. Shock-damaged quartz confirms the intense forces involved. Its survival in a high-erosion environment makes it a ...
  • Jupiter’s wild youth may have reshaped the entire Solar System
    2025-11-13
    Simulations reveal that Jupiter’s rapid growth disrupted the early solar system, creating rings where new planetesimals formed much later than expected. These late-forming bodies match the ages and chemistry of chondrite meteorites found on Earth. The findings also help explain why Earth and the other rocky planets remained near 1 ...

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!
