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 🌀

A 'forbidden' black hole merger that shouldn't exist?! And spacetime warping might be the loophole that explains it 🤯 This is exactly why gravitational wave astronomy is blowing my mind lately!

"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

A 'forbidden' merger in the pair-instability mass gap?! Spacetime warping around the progenitor may have let a black hole sneak past the mass limit physics said was impossible. My brain is doing backflips 🌀🕳️

💁🏻‍♀️ 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.

Even quiet #blackholes create winds, new Milky Way observations reveal
New observations reveal a cone-shaped path leading away from #SagittariusA* that could only be carved by a hot wind. “We’ve never seen gentle breezes from black holes, but likely that’s what they do most of their lives,” says #astrophysicist Lena Murchikova of Northwestern University in Evanston, Ill. “Now, for the first time, we see this gentle breeze from the #blackhole.”

James Webb Looked Into Sagittarius A… What it Saw Terrified Scientists

Peering 26,000 light-years into the heart of our galaxy, the JWST has captured a constant, "random" stream of blinding flares erupting from the accretion disk of Sagittarius A*. The sheer energy and lack of any predictable pattern in these flares have left astrophysicists scrambling to explain the extreme physics at play.

Scientists uncovered a #binarystar system close to #blackhole near center of #MilkyWay, confirming a hypothesis made by happenstance nearly a century ago, according to a paper published in Nature Communications. Scientists previously predicted the existence of a binary #star system -- one in which two stars are gravitationally bound to one another around a common center of gravity -- in the vicinity of the black hole at the center of the galaxy, called #SagittariusA*.

Artist's illustrations of #BlackHoles often have this characteristic ring which is in front of the #BlackHole and continues "above". This ring is an #AccretionDisk made of hot matter on an orbit of the black hole. The strange shape of this ring is due to light bending by the black hole's incredible strong gravitation, which makes something which is *behind* the black hole appear to be above it. [1/3]
