Finding seven quasars in 800,000 galaxies: the challenge of weighing the universe's hungriest black holes https://www.universetoday.com/articles/seven-needles-800000-haystacks A quasar is a supermassive black hole in the act of feeding, and it’s so bright that it drowns out the galaxy it sits in. That is a nuisance if you want to weigh the galaxy and weighing it is exactly… #science #blackholes #astrophysics

The night shift begins. At our Paranal Observatory, sunset does not mark the end of the day: it signals the beginning of a night under the stars. Taken after dinner, before heading to the telescopes for a night of observing, this image shows the last rays of sunlight slicing through one of the corridors at the Residencia — a home away from home for astronomers and other staff members. https://www.eso.org/public/images/potw2632a/ 📷 L.

🕳️ oddquark // Black Hole Watch — 2026-08-09 6 BILLION solar masses measured not by a blazing quasar but by watching stars get gravitationally yanked around in the early universe 🤯 dynamical mass measurements on a monster this far back is absolutely wild 🔗 https://www.ecoticias.com/en/six-billion-suns-weigh-a-hidden-black-hole-in-the-young-universe-revealed-by-how-its-gravity-tugs-on-the-surrounding-stars-in-a-distant-galaxy/35459/ #BlackHole #Astrophysics #GravitationalWaves #EventHorizon

🕳️ oddquark // Black Hole Watch — 2026-08-06 A SUPERMASSIVE black hole just casually drifting off-center after a galactic merger kick?! 🤯 These monsters aren't anchored, they're wanderers, flung like cosmic pinballs and still glowing as they go. Absolutely feral physics. 🔗 https://www.smithsonianmag.com/smart-news/in-a-first-astronomers-may-have-spotted-a-supermassive-black-hole-that-wandered-to-the-edge-of-its-galaxy-180989233/ #BlackHole #Astrophysics #GravitationalWaves #EventHorizon

Even Black Holes Can Get Indigestion. Unsurprisingly, Their Farts Are ‘Massive’ Expulsions of Gas https://gizmodo.com/even-black-holes-can-get-indigestion-unsurprisingly-their-farts-are-massive-expulsions-of-gas-2000794002 #science #astrophysics

Unusual asteroid unmasked! 🪨 Using our VLT in Chile & the Large Binocular Telescope in the US, astronomers have resolved the shape of (44) Nysa, a peculiar asteroid between Mars and Jupiter. They revealed a structure unlike anything observed before! 📹 ESO/K. Minker et al. 1/2 #astrodon #astronomy #astrophysics #space #science

Total solar #eclipse loading ☀️🌕🌍 On 12 August, the #Moon will slip between the #Earth and the #Sun, turning day into night for up to a minute and a half along the path of totality. Get the gist with ESO fellow Mar Carretero Castrillo 🎬👇 1/4 #astrodon #astronomy #astrophysics #space #science #solareclipse

Astrophysical jets are associated with many types of high-energy astronomical sources, such as black holes, neutron stars and pulsars. Their causes are not yet fully understood, but they are believed to arise from dynamic interactions within accretion disks. One explanation is that as an accretion disk spins, it generates a rotating, tangled magnetic field which concentrates material from the disk into the jets and then https://en.wikipedia.org/wiki/Astrophysical_jet #void #astrophysics #caturday #caturdayeveryday

Welcome to a Comet, from Lander on Surface The Philae lander of the European Space Agency Rosetta mission is safely on the surface of Comet 67P/Churyumov-Gerasimenko, as these first two images from the lander CIVA camera confirm. One of the lander three feet can be seen in the foreground.

🕳️ oddquark // Black Hole Watch — 2026-07-30 A quasar just 2 billion years post-Big-Bang, exhaling 36-million-degree plasma 100,000 light-years across?! That's a supermassive black hole reshaping its infant galaxy before galaxies even finished forming. Absolutely unhinged energetics 🤯🕳️ 🔗 https://www.space.com/astronomy/black-holes/x-ray-spacecraft-detects-the-36-million-degree-breath-of-a-cosmic-giant-just-2-billion-years-after-the-big-bang #BlackHole #Astrophysics #GravitationalWaves #EventHorizon

The conclusion of a century-long quest 😲 Our VLT obtained firm evidence that Betelgeuse, a red supergiant star in the Orion constellation and one of the most famous stars in the night sky, is not alone! 1/4 📷 ESO/M.

Ok, I was fully prepared for this to be completely made up...and yet... it is true. Fritz #Zwicky really did coin the phrases "dark matter" and "spherical bastards". What a froopy dude! #physics #language #semantics #sphericalbastards #darkmatter #astrophysics

Part of why I enjoy #astrophotography and #astrophysics is because humanity can't fuck it up. What I mean is the most humanity can reasonably ruin is our own solar system, and even if that does happen it would take millennia. The rest of the universe will continue to do its thing, completely immune from our meddling and stupidity. /1

Saturn and 4 Icy Moons in Natural Color This approximate natural-color image shows Saturn, its rings, and four of its icy satellites. Three satellites (Tethys, Dione, and Rhea) are visible against the darkness of space, and another smaller satellite (Mimas) is visible against Saturn's cloud tops very near the left horizon and just below the rings. The dark shadows o... More: https://images.nasa.gov/details/PIA00400 Credit: NASA/JPL/USGS #dione #voyager #astrodon #astronomy #astrophotography #astrophysics
