Wake up, wake up, get up and shine! The black hole begins to flash, scientists are surprised (VIDEO) – RT World News



The supermassive black hole in the center of the Milky Way has just woken up and flashes 75 times brighter than ever before, after silence, which surprises astronomers.

Sagittarius A *, a supermassive black hole that weighs about 4 million solar masses, usually has a low tone with minimal brightness fluctuation. Recently, however, it bloomed 75 times brighter than ever before for no apparent reason.

Earlier this year, Tuan Do, an UCLA astronomer, and his team watched the center of the galaxy using the WM Keck Observatory in Hawaii for four nights. The team observed a strange flash on May 13, recording it in a two-hour timelapse, which shortened the phenomenon to just a few seconds. "unprecedented"The results were published in the Astrophysical Journal Letters.

As Do explains, the material starts with Sgr A * in the brightest light, which means it could have been even brighter before the band began to observe. Astronomers are now collecting data to accurately determine what caused the sudden explosion, although there are several theories.

"Maybe more gas falls into the black hole, which leads to more accretion, which makes it brighter,"Tell the New Scientist. There is also the possibility that the black hole finally began to consume a cloud of gas, known as G2, which approached Sgr A * in 2014.

The Keck Ground Observatory will continue to observe the center of the Milky Way until it is already visible from Earth at night. Meanwhile, many other space telescopes Spitzer, Chandra, Swift and ALMA have recently been observing the center of the galaxy, probably collecting data that could help explain what Sgr A * does.
