An international team of experts has discovered a stellar-mass black hole in the Large Magellanic Cloud, a satellite galaxy of the Milky Way. The researchers also found that the star that gave birth to this black hole disappeared without any visible signs of a powerful explosion, according to the European Southern Observatory..

It is noted that the object was discovered by a team of researchers known for exposing several false discoveries of a black hole..

Such objects are formed when massive stars approach the end of their existence and collapse under their own gravity.. In a system consisting of two stars, the black hole remains in orbit around the companion star. Such black holes are called “sleeping” if their vicinity does not emit a stream of high-energy X-rays, due to which the object can be detected..

Finding sleeping black holes is very difficult.. To find the object VFTS 243, the team examined nearly a thousand massive stars in the Tarantula Nebula region in the Large Magellanic Cloud, looking for binary systems with a black hole as one of the components.. Detecting a black hole in this way is very difficult, since there are many alternative explanations for such a phenomenon..

The researchers also proposed a new model that explains the processes that accompany the appearance of a black hole.. Scientists believe that progenitor stars collapse, but it is not known whether this process is accompanied by a supernova explosion..

The star that gave birth to VFTS 243 collapsed completely, with no signs of a preceding explosion..

Earlier, astronomers using the Very Large Telescope found six galaxies that surround a supermassive black hole. The discovery will allow scientists to understand how supermassive black holes could form and reach colossal sizes in a short time..
