💁🏻‍♀️ TIL: 🔭⚫ A #PennState astronomer explains that supermassive #blackholes sit at the center of nearly every large #galaxy.

Scientists study them by measuring how fast nearby #stars and gas move. Two theories for their formation remain, and the #JWST may help settle the debate.

Bild des Schwarzen Lochs im Zentrum der Milchstraße soll fehlerhaft sein

Ein japanisches Forschungsteam äußert Zweifel an der berühmten Aufnahme. Der dunkle Fleck soll ein Artefakt sein. Fachleute verteidigen das Bild

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]
