Black holes are the cosmic masters of hide-and-seek. Einstein predicted that they existed in the year 1916, but it took over 100 years before a telescope the world scored the first image of a black hole. They are shy animals that avoid detection, because they swallow light. Even so, the astronomers see the telltale signs of black holes in the universe through the study of various forms of radiation, such as X-rays. So far, that is been discovered worked — and a huge number of black holes, the search for these characters.

But, a completely new detection method, developed by researchers at The Ohio State University, suggests that there is a whole population of black holes that we have missed so far, can<./p>

The results, published in the journal Science on Nov. 1, detail the discovery of a black hole is orbiting the massive star 2MASS J05215658+4359220 (J05215658-short) using the data taken from earth with telescopes as well as Gaia satellite observations. The team shows J05215658 is surrounded by a massive invisible companion, and you suspect it could be a whole new class of black holes.

“We want to show this note that there is a group of people that we don’t really probe on the search for black holes,” said Todd Thompson, an astronomer at Ohio State University and lead author of the study, in a statement.

in General, a binary system such as this-where a black hole orbits a star, — it is easy to see, since the black hole force pulls the enormous amount of difficult material from the star, the illumination of the black hole radiation. Astronomers can detect from earth. But if the black hole is too small, it could not be, the interaction with the star in this way, and remains invisible. This is the case with J05215658.

propose to The team, the new black hole is likely to be discovered were 3.3 times more mass than the sun, which would make it the lowest-mass black hole. However, there are potential black hole could be heavier up to six times than the sun, because it is a little room built into the calculations. Would it discoveries in accordance with the current black hole.

another possibility is the mysterious object has a very large neutron star may is. When stars die, you have two options for the cosmic beyond, based on their mass: Big stars collapse into a black hole, and small stars, the stars are a dead, neutron. Neutron stars are small and incredibly dense, and are believed to reach to 2.5 times as massive as the sun, before it collapses into a black hole itself.

to the puzzle, astronomers need to discover, similarly-sized objects lurking in the cosmos and to realize what you are exactly . As astronomers better to hide the cosmic-and-seek, find, more black holes of different sizes, the secrets of the black hole will begin the formation and evolution to decrypt it.
