A star whipping around Sgr A* faster than anything ever clocked?! 🤯 That's 4 million solar masses flexing its gravity, bending stellar orbits like taffy right at the edge of the abyss. Absolutely unreal.

A star screaming around Sgr A* faster than any star we've ever clocked?! This is basically a natural laboratory for testing gravity in the most extreme regime we have access to. Absolutely wild 🌌⚡

S301 is a very normal #star in a very unusual neighbourhood.
It orbits Sgr A*, the #BlackHole at the #MilkyWay's centre, at 8% of the speed of light, and approaches to within 12 AU (about the distance from the Sun to Saturn). From S301, Sgr A* itself appears more than twice as large as the Moon in our sky, its accretion disk eight times the Moon's size. S301’s sky twists, stars change hue, and local time proceeds nonlinearly.

Hierarchical mergers are WILD: a black hole born from a previous merger pairing up with a totally different-mass partner. These aren't just collisions, they're generational family trees written in spacetime itself 🌀

"We've never seen a black hole – so can we ever really know what they are?" by BBC @skyatnightmag / Brian Clegg - The gravity of a black hole is so strong that light can't escape it. So there's nothing to see or take pictures of. Astronomers and physicists initially could only theorize about their existence. Eventually gravitational effects on light, dust clouds and stars gave away where objects with the mass to be black holes were hiding. https://www.skyatnightmagazine.com/space-science/weve-never-seen-a-black-hole #astronomy #BlackHole #science

If I know any astrophysicists: I was reading a brief news blurb about the Max Planck Institute's interpretation of data from the Arctic IceCube Neutrino Observatory, that led them to conclude they were observing a blazar with gravitational lensing due to dark matter.
And a random question occurred to me. What's the interaction between dark matter and black holes? I don't recall reading anything about this over the years. I'm wondering if it forms a normal accretion disk, and if we can see the radiation from that, or if not, what does actually happen. Can black holes "eat" dark matter or no?

S301 whipping around Sgr A* at 25,000 km/s, just 11.5 AU out?! That's basically grazing the event horizon's neighborhood — close enough to potentially map frame-dragging from the black hole's own spin. Spacetime is not a metaphor here 🌀

💁🏻♀️ TIL: 🌌⚡ Astronomers in #Chile confirmed the fastest #star ever measured in the #MilkyWay, S301, which swings around Sagittarius A*, the #blackhole at our #galaxy’s center.
At closest approach it travels over 24,000 km per second, roughly 8% of #lightspeed. The result tests how #gravity warps #space and #time and could help measure the black hole’s spin.
