    Dimethyl Sulfide (DMS) has been in the news again, this time for its discovery in the atmosphere of the hycean world K2-18b as a potential biosignature. In an interesting twist, astronomers have also detected DMS in comets and in giant molecular clouds. It shows there must be an abiotic way ...

    Take a look at the Moon through binoculars or a telescope and its clear that its been bombarded through history by space rocks. Some of the impacts are energetic enough that debris is ejected from the surface facer than the Moon’s escape velocity. Much of this rock finds its way ...

    Looking up at the night sky, it’s reasonable to believe that our Solar System is largely empty after all the only things easily visible are the planets. In reality its a cosmic shooting gallery and it’s just a matter of time before an asteroid slams into Earth. A team of ...
  • 2025-04-23
    If we need more evidence that our Solar System is not representative of other solar systems, take a look at BD+05 4868. It's a binary star consisting of a K-dwarf and an M-dwarf about 140 light-years away. It's not just the binary star sets the system apart from ours. A ...

    NASA’s Lucy spacecraft made a successful flyby of the second asteroid on its must-see list over the weekend, and sent back imagery documenting the elongated object’s bizarre double-lobed shape. It turns out that asteroid Donaldjohanson — which was named after the anthropologist who discovered the fossils of a human ancestor ...

    When we explore space, we make discoveries — about never-before-seen asteroids, unusual exoplanets, and even our own planet. But to find out new things, we have to continue seeking.
  • 2025-04-11
    Comets, moons, tiny twisters, and blueberries — they may be small, but they’re far from insignificant.

    Catch this spectacular comet over the next few weeks.
  • 2025-01-31
    From galaxies to stamps to asteroid samples, some collections never go out of style.
  • 2025-01-30
    Experts weigh in about the recently discovered near-Earth asteroid 2024 YR4 that has about a 1% chance of impacting Earth on Dec. 22, 2032.
  • 2024-12-20
    Perseverance makes it to the Jezero Crater rim, and we’re antsy to start another year of space exploration.

  • 2025-04-29
    Los Angeles CA (SPX) Apr 22, 2025 A newly published study by SETI Institute researchers suggests that the irregularity of certain meteor showers arises not from chaotic planetary influences but from the subtle, yet consequential, motion of the Sun itself. The findings, presented in the journal Icarus, offer a fresh perspective ...

  • 2025-04-19
    In a study co-authored by a Texas A&M University scientist, researchers have revealed new insights into the geological history of Mars's Jezero Crater, the landing site of NASA's Perseverance rover. Their findings suggest that the crater's floor is composed of a diverse array of iron-rich volcanic rocks, providing a window ...
  • 2025-04-16
    There is a large diversity in the chemical composition of astronomical objects such as planets, comets, circumstellar envelopes, or galactic gas clouds. One great challenge in astrochemistry is to understand in detail how this diversity arises from the cosmic backdrop of the cycling of matter between star birth and destruction, ...
  • 2025-04-16
    A QUT-led study analyzing data from NASA's Perseverance rover has uncovered compelling evidence of multiple mineral-forming events just beneath the Martian surface—findings that bring scientists one step closer to answering the profound question: did life ever exist on Mars?
  • 2025-04-16
    A team of researchers at the University of Oxford have uncovered crucial evidence for the origin of water on Earth. Using a rare type of meteorite, known as an enstatite chondrite, which has a composition analogous to that of the early Earth (4.55 billion years ago), they have found a ...
  • 2025-04-14
    An international team of researchers may have answered one of space science's long-running questions—and it could change our understanding of how life began. Carbon-rich asteroids are abundant in space yet make up less than 5% of meteorites found on Earth.
  • 2025-04-01
    Could microbes survive in the permanently shadowed regions (PSRs) of the moon? This is what a recent study presented at the 56th Lunar and Planetary Science Conference (LPSC 2025) hopes to address as a team of researchers from the United States and Canada investigated the likelihood of long-term survival for ...

    For decades, scientists believed Vesta, one of the largest objects in our solar system's asteroid belt, wasn't just an asteroid and eventually concluded it was more like a planet with a crust, mantle and core. Now, Michigan State University has contributed to research that flips this notion on its head.

    New research has revealed that a massive meteorite struck northwestern Scotland about 200 million years later than previously thought, in a discovery that not only rewrites Scotland's geological history but alters our understanding of the evolution of non-marine life on Earth.
  • 2025-04-24
    Carbon-containing meteorites look like they had less severe impacts than those without carbon because the evidence was blasted into space by gases produced during the impact. The discovery not only solves a 30-year-old mystery, but also provides guidelines for a future sampling mission to Ceres.

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!
