Astronomers have discovered the black hole closest to the earth.Fortunately, it is small



Astronomers believe that they have discovered a small black hole whose mass is so small that it is classified as proprietary. Best of all, it is exciting to be nearby.

In the Milky Way galaxy about 1500 light years from our planet, this is a constellation called Monoceros, which is the closest black hole candidate yet to be discovered by our planetary scientists.

The Ohio State University team named it “Unicorn”, which is a hint of a black hole house and its extremely rare hat in nature.

Astronomer Tharindu Jayasinghe said: “When we looked at the data, this black hole-unicorn came out.”

So how could we not see it before? Facts have proved that we have enabled astronomical blinds.

Theoretically, black holes can exist in a range of masses, from tiny primitive planets to super-giant stars that power the heart of galaxies. However, when it comes to the black hole formed by the collapsed core of the Death Star, astronomers have discovered some “mass gaps”

; over the years.

If a star collapses to less than about 2.3 times the mass of the sun, it will end up being a neutron star, not a black hole. Moreover, until recently, we have not found any stellar black holes less than 5 solar masses-this leaves us with a mass gap.

Until we discover any objects in the gap, their existence has been so dubious that when astronomers noticed a nearby red giant star being pulled by something, they initially thought it was a tiny invisible Possibility of partner.

But Jaya Singh sees it in a different way. As a graduate student, his supervisor told him about the possibility of a potentially tiny black hole, and he wanted to investigate.

He analyzed data from various telescope systems and satellites, and then got into the red giant in the Monoceros constellation in the final stage of his life.

The speed of the star and the way it is pulled by gravity implies a small black hole orbiting it. The size of this dark and silent companion is calculated to be about 3 solar masses.

“Just as the gravity of the moon distorts the earth’s oceans, causing the oceans to bulge toward and toward the moon and produce high tides, black holes can also twist stars into rugby-like shapes, with one axis longer than the other.” Todd Thompson explained that he has helped discover other tiny black holes in the past.

“The simplest explanation is that this is a black hole-in this case, the simplest explanation is the most likely.”

For decades, it was not clear whether there was anything in the mass gap between the two forms of stars.

The unicorn has now joined several other small black holes to help solve this mystery. The result has not been officially verified, but for now, it seems to be a strong candidate for a black hole phenomenon in the middle of the mass gap.

Thompson said: “I think the field is working in this direction to really find out how many low-mass, how many intermediate-mass, and how many high-quality black holes there are, because every time it finds it, it will give you an idea of ​​which stars are collapsing. Which explosions and the clues between them.”

Who knew there were more small black holes for us to discover. Ready or not, the astronomers are here.

The results have been accepted for publication in Monthly Bulletin of the Royal Astronomical Society The preprint can be found here.
