There’s a supermassive black hole – 4 million times our sun’s mass – in the center of our Milky Way galaxy. Astronomers who’ve measured star movements near this central black hole are now saying there might be a 2nd companion black hole near it.

Thousands of exoplanets may orbit supermassive black holes
It sounds unbelievable, but a new study from Kagoshima University and the National Astronomical Observatory of Japan says that exoplanets – thousands of them – could be orbiting supermassive black holes. Source: https://earthsky.org/space/thousands-of-exoplanets-may-orbit-supermassive-black-holes…
Black hole hurls star out of Milky Way
Astronomers have spotted a star – S5-HVs1 – speeding out of the Milky Way at around 4 million miles (more than 6 million km) per hour. They believe it’s being ejected from our galaxy after venturing too near the giant black hole at the Milky Way’s heart about 5 million years ago.

How to find a wormhole … if they exist
A team of physicists proposes that perturbations in the orbits of stars near supermassive black holes could be used to detect wormholes … if they exist. Source: https://earthsky.org/space/wormholes-how-to-find…
Not long ago, the center of our Milky Way galaxy exploded
Researchers have found evidence of a cataclysmic flare that punched outward in both directions from our galaxy’s center, reaching so far into intergalactic space that its impact was felt 200,000 light-years away.

Milky Way’s black hole appears to be getting hungrier
“We have never seen anything like this in the 24 years we have studied the supermassive black hole. It’s usually a pretty quiet, wimpy black hole on a diet. We don’t know what is driving this big feast.” Source: https://earthsky.org/space/milky-ways-black-hole-appears-to-be-getting-hungrier…
Milky Way’s black hole just flared, growing 75 times as bright for a few hours
Even though the black hole at the center of the Milky Way is a monster, it’s still rather quiet. Called Sagittarius A*, it’s about 4.6 million times more massive than the sun. Usually, it’s a brooding behemoth. But scientists observing Sgr. A* with the Keck Telescope just observed its brightness blooming to over 75 times normal for a few hours. Source:…
