🌌 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

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

Replying to
I guess we'd love to know ourselves. There's so many little mysteries of U.S. and world history that remain unsolved, forever indeterminate most likely because there's just not enough information. History fades away into conjecture and hypothesizing on the basis of minute fragments of surviving evidence, but the same can be said of #astronomy and #cosmology. History isn't "soft" any more than physics. It's very material and substantial, the spine of humanity. It's not good that folks have been propagandized into regarding history as roughly equivalent with mythology, all equally conjectural and speculative and thus a free playground for rogues and tricksters.

RE: https://universeodon.com/@HollyCo26588808/116920465634755187 “Even though these supernova events can shine brilliantly, with typical intrinsic brightnesses that are about the equivalent of ten billion suns, that only represents a tiny amount of the energy liberated during a core-collapse event: between 0.1% and 1% of the total energy generated.” 😮 #astronomy #cosmology
