New information from the Hubble Space Telescope seems to indicate that a moving black hole has been detected. According to information published in the media Smithsonian magazinethe object will hover around our galaxy, the Milky Way, about 107,826 or 160,934 kilometers per hour.
The supposed black hole is about 5000 years old. the distance of light from the Earth, comments the above medium. In addition, Kailash Sahu, an astronomer at the Space Telescope Science Institute, told Newsweek the reasons why they believe that it is an object of this nature.
Our discovery of a black hole is consistent with theoretical calculations that there should be about 100 million black holes in our galaxy.
So, assuming that black holes follow a stellar distribution, one would expect, statistically, that the nearest black hole could be about 80 light-years away.

Scientists are not entirely sure of its nature
Until now, it is assumed that it could be a black hole, according to data obtained by the Space Telescope Science Institute. The reason is simple: the researchers’ calculations show that this object has a mass equivalent to 7 masses solar. This is consistent with the description of a black hole.
However, the team from the University of California got very different results. According to their calculations, a celestial object has a mass of 1.6 to 4.4 solar masses.. This would indicate that instead of a black hole, Hubble would have discovered a neutron star.
Data published NASA were based on data obtained by the Space Telescope Science Institute. A) Yes, in their publications they throw that this is a black hole that roams freely in our galaxy.
In addition, these last explained how these types of objects are formed moving. Something that until now scientists have been able to theorize, but not fix live.
The black holes roaming our galaxy are born from rare monster stars (less than one thousandth of the galaxy’s stellar population) that are at least 20 times more massive than our Sun. These stars explode as supernovae, and the remnants of the core are destroyed. gravity into a black hole. Since the self-detonation is not perfectly symmetrical, a black hole can pass through our galaxy like a cannonball.

How to detect a moving black hole
To begin with, it must be clarified that it is impossible to photograph one. These are objects invisible to the human eye., and lies in the fact that they absorb all the light that can be around them. Because of this, finding something rather strange, now imagine finding someone who does not stand still.
Scientists know for sure that when objects move through space, a phenomenon called gravitational microlensing occurs. When a hole passes in front of a star, the light is deformed. So, depending on how the light changes, scientists can estimate the size of the object that caused the event.
It is the first free-floating black hole or neutron star discovered using gravitational microlensing. With microlensing, we can examine these single compact objects and weigh them. I think we’ve opened a new window on these dark objects that can’t be seen in any other way.
