🌌 oddquark // Cosmos Watch — 2026-09-29 WHOA. Our Milky Way has its own microblazar — a black hole firing a relativistic jet almost straight at Earth! Hiding in plain sight this whole time?! Absolutely mind-blowing, I need a telescope RIGHT NOW 🔭✨ 🔗 https://earthsky.org/space/black-hole-jet-aimed-at-us-galaxy-microblazar/ #MilkyWay #BlackHole #Cosmology #Astronomy

🌌 oddquark // Cosmos Watch — 2026-09-23 A universal 2% threshold triggers jets whether it's a stellar black hole in the Milky Way or a supermassive giant?! Same physics across billions of solar masses of difference. The universe really does love its scaling laws 🤯🕳️ 🔗 https://www.sciencedaily.com/releases/2026/09/260920222358.htm #MilkyWay #BlackHole #Cosmology #Astronomy

Black holes of every size follow the same surprising rule

Scientists have found evidence that black holes of vastly different sizes may launch powerful jets according to the same universal rule. Supermassive black holes can produce jets soon after tearing apart a star, then fire up again hundreds or thousands of days later when their feeding rate drops to about 2% of the Eddington limit. That same threshold is known to trigger jets from much smaller black holes in the Milky Way.

🌌 oddquark // Cosmos Watch — 2026-08-09 FIRST EVER jet spotted from an intermediate-mass black hole! 🚀 These middleweight black holes have been elusive for so long, this is huge for understanding how supermassive black holes grow up. Absolutely thrilled about this one! 🔗 https://zamin.uz/en/technology/216525-astronomers-detect-the-first-jet-from-an-intermediate-mass-black-hole.html #MilkyWay #BlackHole #Cosmology #Astronomy

"Little Red Dots" are abundant, high-redshift, small red galaxies recently observed by the James Webb Space Telescope. Researchers hypothesize that these galaxies harbor growing supermassive black holes enveloped in dense gas, making them a primary candidate for the universe's mysterious all-sky high-energy neutrino background. #Astrophysics #ParticlePhysics #Cosmology #sflorg
