Centre of the Milky Way ‘recently’ exploded

Technology
The black hole at the centre of the Milky Way recently exploded according to new research, shooting expanding beams of energy into deep space like a nuclear lighthouse,New research has discovered that the event, known as a Seyfert flare, created two cones of ionising radiation which sliced through the galaxy and even impacted cosmic bodies outside of it. Occurring just 3.5 million years ago - practically last week on a cosmic scale - the flare was so powerful that it hit the Magellanic Stream, a trail of gas extending between the Large and Small Magellanic Clouds, nearby dwarf galaxies.

Astronomers find star recently ripped apart by black hole

Science
Sept. 26 (UPI) -- NASA's Transiting Exoplanet Survey Satellite has spotted the remnants of a star that was recently shredded by a supermassive black hole -- a first. Astrophysicists and cosmologists estimate supermassive black holes are located at the center of most galaxies. When stars wander too close, a black hole's tremendous gravitational pull can rip it apart. The violent interaction is known as a tidal disruption event, or TDE. Scientists can come to better understand the dynamics of black holes by studying the spectral signatures of TDEs. The tidal disruption event ASASSN-19bt was first spotted by an international network of telescopes called the All-Sky Automated Survey for Supernovae. TESS was able to observe the TDE, as well, providing complementary images of the event. When ...
