A Black Hole's Corona Blazes Like the Sun's ⚡ экспресс
Original: "Observation of A Solar Like Magnetic Reconnection Event in an AGN Corona with XRISM"
Flares from a distant galaxy prove that black holes heat their coronas just like the Sun — with magnetic sparks.

In a distant galaxy, something erupted just like on the Sun — but trillions of times stronger. Astronomers watched as the black hole at the center of NGC 3783 heated its corona with sparks of magnetic reconnection. The same mechanism powers solar flares and may also drive the most powerful gas ejections — a key to understanding the 'hot hearts' of faraway galaxies.
🎯 The Sun's corona is superheated to 1–3 million degrees, while its surface sits at just 5,500 °C. The reason? Constant snapping of magnetic arcs.
