Galaxy M87

At the center of the galaxy M87, there is an active supermassive black hole: Pōwehi. What does this mean? Black holes are mainly divided into two types: Stellar-origin black holes (born from stellar explosion (supernova) and supermassive ones that have millions of times the mass of our sun and are found in galactic centers. Regardless of the type of black hole, all the mass is concentrated in a point of infinite density and gravity: The Singularity. Typically, when active, they have accreting matter into a disk (accretion disk) that is super bright and can be as hot as a star and because of this disk, some matter can "escape" in the form of jets that go almost at the speed of light, unlike inactive black holes which are... Let's say calmer but even so, you won't want to give them a hug .
