The closest black hole to Earth has found everything

KOMPA.com – This was discovered by an international group of astronomers black hole the closest to Land.

Black hole known as Gaia BH1 is 1600 light years away and has a mass about 10 times that of our Sun.

Black holes are the densest objects in the universe. Whether it’s a tiny black hole with the mass of a star or a supermassive hole at the center of a galaxy, these objects have such strong gravitational fields that not even photons of light can escape their event horizon.

While this newly discovered black hole, it is a stellar-mass black hole.

Their mass is at most 100 times that of the Sun and is created in a massive supernova explosion.

There should be about 100 million of these objects Milky Way, but only a few have been found. Among them, almost all of them are actively collecting material from their companion stars and releasing large amounts of X-rays.

But it is different with Gaia BH1. The black hole takes nothing from its companion star, so it is considered inactive.

To collect IFL science, On Saturday (11/5/2022) Gaia BH1 was initially spotted by the European Space Agency’s Gaia spacecraft. Gaia noticed a strange strangeness in her companion star, as if the gravity of a large object was affecting its movement.

Follow-up observations with the Gemini International Observatory expanded the readings of the star’s motion and, in fact, the analysis confirmed that the star was likely orbiting a black hole.

Such a binary system was first discovered in the Milky Way galaxy.

Kareem El-Badry, an astrophysicist at the Center for Astrophysics, Harvard & Smithsonian and the Max Planck Institute for Astronomy, said that while there were many claims to detect such a system, nearly all of the findings were subsequently disproved.

“While this latest discovery is the first clear revelation of a Sun-like star in a large orbit around a stellar-mass black hole in our galaxy,” he said.

The team considers this detection unambiguous, after years of hunting dormant black holes. Furthermore, the same researchers said they did not clearly know how the system was formed.

The binary system is actually made up of a massive star about 20 times the size of the Sun, orbiting a Sun-like companion that is still observable.

This huge star will evolve into a red supergiant within millions of years.

The star’s outer layer will then engulf its companion before causing a supernova to explode.

How the companion star survived all of this remains a mystery, suggesting an incomplete understanding of how black hole tracks form and evolve.

“Interestingly, this system is not easily adaptable to standard binary evolutionary models. This raises many questions about how the binary system formed and how many dormant black holes are out there,” El-Badry added.

The results published in Mothly Notices of the Royal Astronomical Society.
