💁🏻‍♀️ 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.

Milky Way's fastest star orbits our supermassive black hole so closely it feels its spin

During its closest passage to the black hole, the star travels at around 25 000 kilometres per second or over 8% of the speed of light — making it the record holder for the fastest star in the Milky Way

Sterne trotzen dem Schwarzen Loch: Kölner Forschung zeigt stabile Bahnen um Sagittarius A*

Neue Beobachtungen mit dem Instrument ERIS am Very Large Telescope widerlegen die Annahme, dass das supermassive Schwarze Loch im Zentrum der Milchstraße nahegelegene Staubobjekte verschlingt
