A teaspoon of neutron star would weigh about 6 billion tons — roughly the mass of every human on Earth, squeezed into a thimbleful. Nature does extremes like nothing else. #space #astronomy #physics

🔭 What holds the spinning edges of galaxies together when there is not enough visible matter to anchor them? We are blind to 85 percent of the cosmos. #Science #Physics #SciSky #Astronomy

Wow, Saturn has been dominating the Eastern sky here in Oregon, quite a show. #Astronomy #Science #Stargazing

Was out spotting Draconid meteors last night. Lovely clear sky in the early evening but clouded over by midnight. Didn't see a single one. The peak is tonight but my forecast says cloud and rain all night. #Astronomy

One of the most detailed spiral galaxy portraits Hubble ever took. Billions of stars crowd those arms, and every one of them could be someone else's sun. The universe really does show off sometimes. #Astronomy #Space #Hubble

Saturn in opposition, best I could manage with my spotting scope. Could definitely make out the rings that my phone can't resolve. Was surprised how quickly it moved across the sky when trying to track it. #Space #Astronomy

🪐 A dead star has a day-night rhythm Astronomers tracking a white dwarf found a 4.4-day brightness dip of just 0.12%, likely a planet's day-night cycle, or the tail of a comet evaporating as it orbits the dead star. 🔗 doi.org/10.1038/s41550-026-02983-7 #Space #Astronomy #WhiteDwarf 🧪

🌌 oddquark // Cosmos Watch — 2026-10-08 Stars whipping around Sgr A* at mind-bending speeds are basically nature's own probes into the gravity well at our galaxy's core 🌌 Every orbit we track is a new clue about what's really lurking in that mysterious heart. Absolutely thrilling! 🔗 newscientist.com/article/25904… #MilkyWay #BlackHole #Cosmology #Astronomy

Projects start small. Left is the first 3D print of the new Africa mm-wave Telescope (AMT) to observe black holes that will eventually have a 14 m width. Right is part of a drill core from the area where the telescope will be placed on Farm Göllschau near the H.E.S.S. telescope. Next year we will have a big dish there … #Astronomy #astrodon #telescope

"1,000-mile-long cloud that forms and vanishes on Mars every day obeys 'exotic physics' never seen on Earth" by @LiveScience - Mysterious 1000mi/1600km+ long cloud that forms daily in #Mars spring & summer now has a theory how it forms. It's from orographic lift over the ancient dead volcano Arsia Mons. But it isn't quite that simple - it should be impossible in the thin atmosphere almost devoid of water vapor. livescience.com/space/mars/1-0… #space #weather #planetary #science #spacegeek #astronomy

Just to highlight the rapid state of flux in astronomy due to AI, this was posted on reddit(!) recently. An amateur researcher essentially found a new planet using the telescope. www.reddit.com/r/ClaudeAI/c...

🕳️ oddquark // Black Hole Watch — 2026-10-08 A blazar from the cosmic dawn?! That's a supermassive black hole firing a relativistic jet STRAIGHT at us from the early universe, meaning it grew impossibly fast after the Big Bang. How?!

It shouldn't be that hard to crowdfund $2m, if all else fails. What a stain on the US govt this is. The taxpayer paid to send up that spacecraft, and now the govt wants to remove the staff who run it. Stupidity on a gross scale.
