    We’re getting better views of interstellar Comet 3I/ATLAS, as it makes its speedy passage through the inner solar system. This week, astronomers at the Gemini North observatory located on Mauna Kea in Hawai’i turned the facility’s enormous 8.1-meter telescope on the object, with amazing results.
  • 2025-07-19
    All eyes are on the newly discovered interstellar object 3I/ATLAS, currently inbound to the inner solar system. Initial observations have revealed that it's rich in water ice, and it's believed that it originated from the Milky Way's thick disk, ancient stars that orbit above and below the galactic plane. This ...

    London, UK (SPX) Jul 14, 2025 A mystery interstellar object discovered last week is likely to be the oldest comet ever seen - possibly predating our solar system by more than three billion years, researchers say. The "water ice-rich" visitor, named 3I/ATLAS, is only the third known object from beyond our ...

    The origin of life is one of the most fundamental and enduring questions of mankind and one of the three greatest Origin Questions in the natural sciences. Recently, China officially launched its Mars Sample Return (MSR) mission, Tianwen-3, marking a significant step forward in planetary exploration. The mission aims to ...

    New images from NASA's Curiosity Mars rover show the first close-up views of a region scientists had previously observed only from orbit. The images and data being collected are already raising new questions about how the Martian surface was changing billions of years ago.
  • 2025-06-23
    Researchers at the universities of Amsterdam and Utrecht have observed the formation of nanocavities in montmorillonite clay under exposure to gamma-aminobutyric acid, a molecule commonly found on meteorites. This hitherto unrecognized phenomenon could be relevant to the origin of life on Earth, by introducing 3D confined nano-environments in clay that ...
  • 2025-06-12
    Georgia Tech scientists have uncovered evidence that a mountain on the rim of Jezero Crater—where NASA's Perseverance Rover is currently collecting samples for possible return to Earth—is likely a volcano. Called Jezero Mons, it is nearly half the size of the crater itself and could add critical clues to the ...

    Astronomers have found a rare form of methanol, a type of alcohol, in a planet-forming disk, providing a critical step in understanding how life beyond Earth may form. This result reveals vital details about the chemical composition of the ice in disks that form planets, and what organic molecules are ...

    Interstellar objects are visitors from solar systems beyond our own, and the third ever such object, known as 3I/ATLAS, has just been discovered. Using the Gemini North telescope, astronomers have captured 3I/ATLAS as it makes its temporary passage through our cosmic neighborhood. These observations will help scientists study the characteristics ...

    Geology is full of detective stories about the Earth's history, and a new paper in Geology by University of New Mexico Distinguished Professors Emeritus Karl Karlstrom and Laurie Crossey, along with their co‐authors, links two iconic geologic landmarks of the American Southwest: the Grand Canyon and Meteor Crater.
  • 2025-07-15
    When the first astronauts walked on the moon as part of the Apollo Program, the concept of lunar habitats ceased being the stuff of science fiction and became a matter of scientific study. With several space agencies planning on sending crewed missions to the moon in the coming decade, these ...

    Ever been late because you misread a clock? Sometimes, the "clocks" geologists use to date events can also be misread. Unraveling Earth's 4.5-billion-year history with rocks is tricky business.

    M-MATISSE could be the first mission to deeply probe Martian space weather, potentially revealing hidden threats and mysteries vital to future human exploration. Preparing to send astronauts to Mars requires a deep understanding of the conditions they will face upon arrival. A proposed mission known as M-MATISSE could serve as ...

    A rare Martian meteorite has revealed complex volcanic processes and mantle heterogeneity on Mars, offering new clues to the planet’s magmatic evolution and thermal history. In a groundbreaking discovery published in the inaugural issue of Planet, scientists at Chengdu University of Technology revealed how a newly identified Martian rock formed. ...

    A 2.35-billion-year-old Moon rock that fell to Earth in Africa is rewriting what we know about lunar volcanism. This rare meteorite, studied by UK scientists and unveiled at a major geochemistry conference, reveals that the Moon was volcanically active far longer than previously thought. With a unique chemical makeup and ...

    A newly discovered comet, 3I/ATLAS, may be the most ancient visitor ever detected, potentially older than our solar system itself. Unlike previous interstellar objects, this ice-rich comet seems to originate from the thick disk of the Milky Way, a region filled with ancient stars. First spotted in July 2025, it’s ...

    China's Chang’e-6 mission has delivered the first-ever samples from the Moon’s far side, shedding light on one of planetary science’s greatest mysteries: why the near and far sides are so different. The South Pole–Aitken Basin, a colossal crater created 4.25 billion years ago, has now revealed clues about ancient volcanic ...

    A surprising discovery from a tiny grain of asteroid Ryugu has rocked scientists' understanding of how our Solar System evolved. Researchers found djerfisherite—a mineral typically born in scorching, chemically reduced conditions and never before seen in Ryugu-like meteorites—inside a sample returned by Japan’s Hayabusa2 mission. Its presence suggests either Ryugu ...

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!
