  1. @Thorium I tried adding you again and it's still saying your server doesn't support collections. I'll retry from time to time.

    I'm kinda surprised nobody else has joined up. I know there must be other meteorite people around here who wouldn't mind being on the list. I just have to find them.

    If anyone #meteorite people are here, post a reply to join up. Let's make this into a legit "group" for discussions.

  2. Sugars are essential #biomolecules, serving as metabolic fuels, nucleic acid backbone components and structural or energy-storage polymers.

    A central question in origin-of-life research is how monosaccharides formed on the primitive Earth, as laboratory experiments under #prebiotic conditions yield insufficient concentrations.

    The detection of #ribose, #glucose and other monosaccharides in #asteroids and #meteorites suggests an exogenous origin, possibly in the interstellar medium (ISM) before meteoritic parent-body formation.

    However, no #sugar has been observed in the ISM so far.

    Now astronomers report the discovery of #erythrulose, a chiral four-carbon ketose, in the ISM.

    Erythrulose appears to be at least eight times more abundant than analogous three-carbon sugars, which remain undetected in our ultrasensitive observations.

    Quantum chemical and astrochemical models indicate that erythrulose forms efficiently on interstellar dust grains from simpler two-carbon aldehydes and alcohols.

    As ketoses readily isomerize into aldoses in aqueous conditions, interstellar erythrulose could have contributed to the sugar inventory available for early metabolic and replication processes.

  9. 📢 I am starting a new Mastodon collection for meteorite-related accounts. ☄️

    👉 This collection is open to all scientists, collectors, dealers, and hunters who specialize in space rocks.

    👉 This is an opt-in collection. If you want to be included, please reply to this thread.

    👉 Please boost for reach.

  10. The Chicxulub impact was a quick and catastrophic event with lasting consequences. Not talking about the thing with the dinosaurs - it drove significant hydrothermal activity for 8 million years across the entire region.

  14. METEORITE QUESTIONS, an ongoing thread. 🧵

    I am a meteorite collector, dealer, and hunter with 20 years of experience. I have worked with numerous universities and scientific institutions.👨‍🔬

    Ask me anything about meteorites and get an informed answer free of AI bullshit.

    If you have a question, post it here in the replies. No matter how old this thread is, I will reply.

  15. There are many types of meteorites, but a bunch of them might have had a common origin in a region just past Jupiter, where planetesimals formed 2–4 million years after solar system formation began.

  19. 💁🏻‍♀️ ICYMI: 🌍🌋 The #Earth's crust accounts for only a tiny fraction of its total volume, leaving the vast majority of our planet largely unseen.

    Researchers are studying seismic waves and ancient #meteorites to better understand the continent-sized mystery blobs and unique #minerals located deep beneath our feet.

  23. I went out into the garden at 10:30pm in the dark to observe the meteorites. I gave myself time for my eyes to adjust. I wrapped up warm. Since I saw exactly zero bright flashes streaking through the heavens here's a picture of a cake i made recently #physics #astronomy #crushing #disappoint #cake #meteorites

  25. Analysing the sample preparation process in meteorites and its impact on the pretreatment of returned samples to Earth: sciencedirect.com/science/arti -> Scientists Found Literal Ink From Ballpoint Pens in Martian #Meteorites: gizmodo.com/scientists-found-l - this doesn't devalue scientific research thus far, but we might need a more unified approach for cleaning important samples, the study says.

  27. RE: flipboard.com/@sciencealert/sc

    Unlike #Earth, our #moon is subjected to a constant #bombardment by #meteorites of all sizes, due in part to the lack of a comparable #atmosphere. However, it is rare for larger craters to be discovered immediately after an #impact. Thanks to NASA's #LunarReconnaissanceOrbiter Camera, a larger impact in late spring 2024 could be described in more detail.
