News hardware What is this black hole 10 times heavier than the sun discovered near Earth?

Scientists have just discovered a black hole near the Earth, the closest to us. It is so dark that it is not possible to observe it with traditional instruments. This is an important discovery.

A nearby ultra-dense black hole

At first glance, this announcement looks very worrying for the Earth. In fact, when it comes to neighbor, it’s 1500 light years away. This means that it would take 1500 years at the speed of light to reach this black hole. To make a comparison, it takes 8 minutes between the Earth and the Sun. On the scale of the Universe, however, it is very small, this is just 1% of the size of our galaxy.

This black hole has not yet been observed. One reason is its density so high that light is absorbed. To compare it to a well-known star, this black hole is 10 times heavier than the sun, but 100 million times smaller. This density prevents us from observing it, because we capture light during spatial observations.

What differentiates it from other observed black holes is that it is silent. It does not devour other stars or clouds of gas. This is the case with the twenty black holes observed to date. These density giants release a large amount of X-rays, more or less easily observable depending on the distance. As a result, this newly discovered black hole is invisible.

Observe what is not observable

This black hole has been talked about for a long time, yet it is impossible to scientifically prove the phenomenon. We observe a star that has a particular and extremely fast orbit around “nothing”. This is where scientists wondered if it wasn’t a black hole.

Astrophysicists then made their own calculations to prove the veracity of this theory. The results have diminished and in fact it is a black hole of an impressive density. But it is also his closeness to us that fascinates. Scientists find the phenomenon so powerful that the theory of two black holes in orbit relative to each other is possible.

The discoveries of dormant black holes are only in their infancy, and a dozen more may be discovered in the coming days. This would suggest that they are much more frequent than traditional voracious black holes. The Gaia telescope has made many observations that could lead to important discoveries.

Astrophysicists estimate that there are still 100 million black holes to be discovered in our galaxy. An astronomical figure that puts into perspective the dimensions of the Earth and of Man in relation to the Universe. We are only at the beginning of the discovery of black holes. Why not imagine discovering even smaller ones at the gates of our Earth?
