  • Meet Orpheus—A hopper mission built to hunt for life in Martian volcanoes
    2026-04-12
    We've spent decades scratching the surface of Mars trying to uncover life there. But we've been searching a barren wasteland bombarded by radiation and bathed in toxic perchlorates. The entire time, it's likely that it's been too hostile to harbor extant life. So if we want a better shot at ...
  • Chang'e mission samples reveal how exogenous organic matter evolves on the moon
    2026-04-11
    Elements essential to life, such as carbon, nitrogen, oxygen, phosphorus, and sulfur, were "delivered" to Earth and the moon during the early stages of the solar system via asteroids and comets impacting their surfaces. These exogenous materials may have provided the chemical building blocks necessary for the origin and early ...
  • If life exists in Venus's atmosphere, it could have come from Earth
    2026-04-07
    The theory of panspermia holds that life is spread through the cosmos via asteroids, comets, and other objects. When the building blocks of life emerge on one planet, impacts can eject surface material into space, which then carries these seeds to other worlds. For decades, scientists have debated whether this ...
  • 'Serendipitous' discovery of Martian ripple marks reveals an ancient sandstorm
    2026-04-02
    The search for life on Mars involves the efforts of scientists from many different disciplines. An important aspect of that search is to study Martian sedimentary rocks for information about the planet's environment when it is likely that the surface environment hosted abundant water and therefore more habitable, around three ...

  • Reading the moon's buried past
    2026-04-15
    The lunar south pole looks chaotic from orbit. Craters heaped upon craters, ancient basins, scarps and slopes tumbling in every direction, it is without doubt, one of the most geologically complicated terrains in the inner solar system. That aside, it's exactly where we intend to send people, since understanding what ...
  • Subaru telescope captures comet 3I/ATLAS composition change
    2026-04-15
    The Subaru Telescope observed the interstellar comet 3I/ATLAS on January 7, 2026, after it made its closest approach to the sun.

  • Life on Mars? Tiny cells just survived shock waves and toxic soil
    2026-04-12
    Mars may be hostile, but it might not be entirely unlivable. In lab experiments, yeast cells survived simulated Martian shock waves and toxic perchlorate salts—two major environmental threats on the Red Planet. Their secret weapon was forming protective molecular clusters that shield critical cellular functions under stress. Without these defenses, ...
  • Something just hit the Moon and left a bright new scar
    2026-04-08
    For all its ancient, familiar features, the Moon is still changing—and sometimes in dramatic ways. Scientists recently identified a fresh 22-meter-wide crater by comparing orbital images taken years apart, revealing a relatively recent impact that no one actually saw happen. The collision blasted bright material outward in striking rays, making ...
  • Meteor impacts may have sparked life on Earth, scientists say
    2026-04-04
    Asteroid impacts may have helped kick-start life on Earth by creating hot, chemical-rich environments ideal for early biology. These impact-generated hydrothermal systems could have lasted thousands of years—long enough for life’s building blocks to form. Scientists now think these environments may have been common on early Earth, making them a ...
  • NASA’s asteroid Bennu sample reveals a hidden chemical patchwork
    2026-04-01
    Scientists studying Bennu samples have discovered that its chemistry is far from uniform.

    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!
