KOMPAS.com – Imagine a black hole that devoured stars, dust, and gas that crossed it. Not from the center of the galaxy as usual, but from the periphery, moving wildly without the bond of gravity to any center.
This is a supermasi-black hole that was recently discovered by NASA’s space telescope.
This makes it the first case of the black wanderer’s black hole scientifically confirmed. Let’s look at learning more about this black hole!

This Supermasi -Black Hole was found wandering
Reported from NASA Sciencethis black hole is about 600 million light years from the earth, and not part of the core of the galaxy where the giant black hole usually persists.
This is the first black hole that is confirmed is completely roaming solitary, not bound in a binary system or galaxy center.
The existence of this black hole was revealed through the tidal disruption (TDE) event. Namely, a rare phenomenon when a star is pulled in and destroyed by extreme gravity from a black hole.
Unusual TDE: When the Star is Ruined by a Black Hole
Usually, TDE occurs at the center of the galaxy and is associated with the central supermasi -black hole.
But this time is different. This phenomenon comes from a distance of around 2,600 light years from the galaxy center, which makes astronomers surprised.
This is the first TDE that is known not at the center of the galaxy, or also referred to as “TDE Offset”.

The TDE phenomenon itself is very dramatic: When a star is too close to a black hole, a strong gravitational force will tear the star into a long ribbon in a process called “spaghetification”.
The stars that were destroyed then surrounded the black hole, producing ultraviolet and optical light explosions that could be observed from the earth.
There are two black holes in one galaxy, but not bound to each other
The increasingly surprising thing is the existence of two supermasi -black holes in the same galaxy.
One is at the center, with a mass reaching 100 million times the mass of the sun, categorized as the core of an active galaxy because it actively spewed energy when absorbing gas.
While the second, the wanderer’s black hole has a smaller mass of about one million times the mass of the sun and is not bound by gravity with the central black hole.
Both of these black holes do not form a binary system, because the distance is too far to lock each other gravitatedly.
