The Milky Way features a black hole that's 4 million times the mass of the Sun, called Sagittarius A* (pronounced A-star).
Until now, black holes have a theoretical proof of its existence, and explore at least one of them is still in practice impossible, because they are located too far away.
For those that don't know, at the center of our Milky Way galaxy lies a black hole which we have named Sagittarius A. That black hole just had a unusual anomaly that caused its brightness to spike 75 times more than normal. However, a couple of months ago the astronomers who work on the project Event Horizon Telescope, published a photo of the shadow of the black hole in the center of the galaxy M87, reports the online edition of the Chronicle.info with reference to NV.
The fact that it's so incredibly massive means that despite its huge distance from Earth, it might prove to be a good candidate for imaging using current technology.

Werner said that police believe that the call came from Europe. "I got swatted", Giersdorf said in the clip . Finch was shot and killed by police.
One team of scientists photographed the brightest flash of infrared radiation that they have ever seen in over 20 years of observation.
Astronomers have learned a lot about the universe and our place in it thanks to high-powered telescopes, but there's clearly still a lot out there that we have yet to even imagine. They hope to find out whether the black hole is more active than usual, or if something else accounts for the unprecedented brightness.
One of the biggest observing campaigns ever performed by Chandra has provided new understanding into why gas near the giant black hole at the center of the Milky Way is extraordinarily faint in X-rays.
Sgr A* grew 75 times brighter as it was spewing out a mysterious flashing burst of energy, and then declined to its normal brightness levels.

Hello Games founder Sean Murray advised the community that hotfixes would be implemented often after the release of Beyond. After the launch of No Man's Sky Beyond , players were encountering issues impacting the game's performance.
The supermassive black hole at the center of the Milky Way, just produced an "unprecedented" bright flash-the cause of which is now unknown. The proximity of Sgr A* makes it the easiest black hole for scientists to study.
Researchers say, though the event much brighter than any other observed in human history, it may have been even brighter than the data lets on since its peak brightness was captured at the start of the telescope's imaging.
They also pointed to a dust cloud that passed near Sgr A* in 2014 but didn't get dramatically torn apart the way astronomers thought it would. The study is now available on a preprint website arXiv. It was later termed as a "cosmic fizzle", however, the astronomers feel that the glowing of the black hole in May might have been a delayed reaction. Normally, the brightness of Sgr A* flickers a bit like a candle, varying from minutes to hours.

But the risk is elevated for older persons and people who live with compromised immune systems. Common sources of standing water include pools and rain barrels, Schaaf said.
