Each several thousands of years, unsuccessful star wander too close in relation to a black hole in the center of the Milky Way. Powerful gravity of a black hole breaks off this unlucky star, letting out a long stream of gas. The new research shows that gas can gather in objects of the size of the planet.
“The unique star can create hundreds of similar objects similar to Earth” – the leading author of a research Eden Girma from Harvard University has reported.
Girma is going to present results of the researches in the form of reports on Wednesday and on Friday at a press conference at a meeting of the American Astronomical Society.
Girma’s calculations show that the closest of these objects weight about the planet can be in several hundred light years from Earth. Such object could have weight in the range from the Neptune to the nekolkikh Yupiterov.
Scientists have also assumed that the vast majority of such objects – 95 percent – will leave a galaxy with a speed of 10,000 km/s. As the majority of other galaxies also has huge black holes in their kernels probably that the same process can be observed also in them.
“Other galaxies, such as Andromeda, shoot these “paper balls” at us all the time” – the coauthor James Gillochon from Harvard-Smithsonian institute of Astrophysics (CfA) says.
