    2025-09-16
    David Bowie once sung ‘Is there life on Mars?’ and along with being a question in a hit song, its also a question that has driven decades of missions to the red planet. From early orbital surveys to rovers hunting for evidence that life once existed beyond Earth the search ...
  • A Spacecraft Could Explore 3I/ATLAS to Learn More About "Cosmic Noon"
    2025-09-16
    An examination of the interstellar object 3I/ATLAS shows that it is likely to be a remnant of the Galaxy's “Cosmic Noon” period, ca. 9 to 13 billion years ago. An examination of the object by an active mission could provide clues about stellar and planetary formation, and maybe the emergence ...
  • Sulphur Volcanoes on Mars May Have Warmed the Planet
    2025-09-16
    Is it possible that Mars could have once been warm enough to support life? New research suggests that volcanic emissions billions of years ago may have created a greenhouse effect that made the red planet surprisingly hospitable, challenging our understanding of early Martian climate. The key lies in unusual sulphur ...
  • Lasers Can Melt Through Extraterrestrial Ice Efficiently
    2025-09-16
    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
    2025-09-16

  • Isotopic analysis determines that water once flowed on asteroid Ryugu
    2025-09-10
    A team of researchers, including those at the University of Tokyo, discovered that liquid water once flowed on the asteroid that spawned near-Earth asteroid Ryugu more than a billion years after it first formed. The finding, based on tiny rock fragments returned by the Hayabusa2 spacecraft of the Japan Aerospace ...
  • One extremophile eats Martian dirt, survives in space and can create oxygen for colonies
    2025-09-09
    Extremophiles are a favorite tool of astrobiologists. But not only are they good for understanding the kind of extreme environments that life can survive in, sometimes they are useful as actual tools, creating materials necessary for other life, like oxygen, in those extreme environments. A recent paper from Daniella Billi ...
  • Ryugu asteroid research reveals mineral history predating any on Earth
    2025-08-25
    In 2020, the Hayabusa2 uncrewed spacecraft successfully returned small fragments from the near-Earth asteroid Ryugu, providing the first pristine samples from a carbonaceous asteroid. Grains from those samples were studied at the National Synchrotron Light Source II (NSLS-II), revealing new details into the asteroid's composition and origin. This insight could ...

Although there is no evidence that microorganisms ever existed on Ceres, the finding supports theories that this intriguing dwarf planet, which is the ...
  • Simple instrument could find Martian DNA if it exists
    2025-08-14
    Mars still holds the promise of being one of the first places in the solar system humanity will colonize.

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!
