- Wakey Wakey, Rise And Shine! Black Hole Begins Flashing, Scientists Baffled (VIDEO)
A supermassive black hole in the center of the Milky Way just woke up and is flashing 75 times brighter than ever observed, after being quiet for more than 20 years, baffling astronomers.
Sagittarius A*, a supermassive blackhole, is normally low key with minimal fluctuation in brightness. Recently, however, it bloomed 75 times brighter than ever before for no apparent reason.
Earlier this year, Tuan Do, an astronomer at UCLA, and his team took observations of the galactic centre using the WM Keck Observatory in Hawaii over four nights. The team observed the bizarre flash on May 13, capturing it in a two-hour timelapse that condensed the phenomenon down to just a few seconds. The “unprecedented” findings have now been published in the Astrophysical Journal Letters.
Here's a timelapse of images over 2.5 hr from May from @keckobservatory of the supermassive black hole Sgr A*. The black hole is always variable, but this was the brightest we've seen in the infrared so far. It was probably even brighter before we started observing that night! pic.twitter.com/MwXioZ7twV
