    Observations by NASA’s SPHEREx (Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer) show the infrared light emitted by the dust, water, organic molecules, and carbon dioxide contained within comet 3I/ATLAS’s coma.

    The Moon has a long history of being smacked by large rocks. Its pock-marked, cratered surface is evidence of that. Scientists expect that, as part of those impacts, some debris would be scattered into space - and that we should be able to track it down. But so far, there ...
  • 2026-02-10
    Mars’ water disappeared somewhere, but scientists have been disagreeing for years about where exactly it went. Data from rovers like Perseverance and Curiosity, along with orbiting satellites such as the Mars Reconnaissance Orbiter and ExoMars have shown that Mars used to be a wet world with an active hydrodynamic cycle. ...

    Martian travel buddies, synchronized Sun science, and a proven leadership team.

    A roundup of key facts and surprising discoveries about the third known interstellar object.

    A Mars rock may hold answers in the search for life, and spacecraft might roll along its surface. Plus, meet the red planet’s Rolling Stones Rock.

    Los Angeles CA (SPX) Feb 10, 2026 Amino acids discovered in samples from the Bennu asteroid may have formed in an icy, radioactive environment in the early solar system, according to a new study led by Penn State researchers. The findings challenge long-held assumptions that these building blocks of life on ...

  • 2026-02-09
    Amino acids, the building blocks necessary for life, were previously found in samples of 4.6-billion-year-old rocks from an asteroid called Bennu, delivered to Earth in 2023 by NASA's OSIRIS-REx mission. How those amino acids—the molecules that create proteins and peptides in DNA—formed in space was a mystery, but new research ...
  • 2026-02-04
    New tools unlock new discoveries in science. So when a new type of non-destructive technology becomes widely available, it's inevitable that planetary scientists will get their hands on it to test it on some meteorites. A new paper, available on the arXiv preprint server, by Estrid Naver of the Technical ...
  • 2026-01-30
    Bacteria that thrive on Earth may not make it in the alien lands of Mars. A potential deterrent is perchlorate, a toxic chlorine-containing chemical discovered in Martian soil during various space missions.
  • 2026-01-27
    New findings from NASA's Perseverance rover have revealed evidence of wave-formed beaches and rocks altered by subsurface water in a Martian crater that once held a vast lake—considerably expanding the timeline for potential habitability at this ancient site. In an international study led by Imperial College London, researchers uncovered that ...
  • 2026-01-25
    For a long time, scientists assumed that Earth's water was delivered by asteroids and comets billions of years ago. This coincided with the Late Heavy Bombardment (ca. 4.1 to 3.8 billion years ago), a period when planets and bodies in the solar system experienced a much higher rate of impacts.
  • 2026-02-10
    Scientists from the Institute of Geology and Geophysics of the Chinese Academy of Sciences (CAS), the CAS Aerospace Information Research Institute, and other institutions, have revised the decades-old lunar crater chronology model, using samples collected from the far side of the moon by China's Chang'e-6 mission and complementary remote sensing ...

    A newly discovered comet has astronomers excited, with the potential to be a spectacular sight in early April. C/2026 A1 (MAPS) was spotted by a team of four amateur astronomers with a remotely operated telescope in the Atacama desert on January 13.

    The current image of Mars as an arid and hostile desert contrasts sharply with the history revealed by its surface. Channels, minerals altered by water, and other geological traces indicate that the red planet was, in its early days, a much wetter and more dynamic world. Reconstructing how this water-rich ...
  • 2026-02-04
    Magnetism on the moon has always been a bit confusing. Remote sensing probes have noted there is some magnetic signature, but far from the strong cocoon that surrounds Earth itself. Previous attempts to detect it in returned regolith samples blended together all of the rocks in those samples, leading to ...
  • 2026-02-02
    Most near-Earth asteroids are thought to drift in from the main asteroid belt. But a small subset may have a much closer origin: the moon. One intriguing example is 469219 Kamoʻoalewa (2016 HO3), an Earth quasi-satellite whose reported spectrum resembles lunar material and which is a target of China's Tianwen-2 ...

    Tiny grains of dust from asteroid Bennu are reshaping how scientists think life’s ingredients formed in space. Scientists previously identified amino acids, the essential components of life, inside 4.6-billion-year-old rocks collected from the asteroid Bennu. These samples were brought back to Earth in 2023 by NASA’s OSIRIS-REx mission. While the ...

    A colossal ancient impact may have reshaped the Moon far more deeply than scientists once realized. By analyzing rare lunar rocks brought back by China’s Chang’e-6 mission from the Moon’s largest crater, researchers found unusual chemical fingerprints pointing to extreme heat and material loss caused by a giant impact. The ...
  • 2026-02-06
    Scientists have found that ancient Martian lakes could have survived for decades despite freezing air temperatures. Using a newly adapted climate model, researchers showed that thin, seasonal ice could trap heat and protect liquid water beneath. These lakes may have gently melted and refrozen each year without ever freezing solid. ...

    NASA’s Perseverance rover has just made history by driving across Mars using routes planned by artificial intelligence instead of human operators. A vision-capable AI analyzed the same images and terrain data normally used by rover planners, identified hazards like rocks and sand ripples, and charted a safe path across the ...
  • 2026-01-27
    Bright white rocks spotted by NASA’s Perseverance rover are rewriting what we thought we knew about ancient Mars. These aluminum-rich clays, called kaolinite, usually form on Earth only after millions of years of heavy rainfall in warm, humid environments—conditions similar to tropical rainforests. Their presence on today’s cold, dry Mars ...

    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!
