First discovered two black holes in the constellation

International astronomers announced they found two black holes in a dense constellation of the Milky Way.

Stefan Umbreit, an astronomer at Northwestern University in the United States, and colleagues found black holes after analyzing data of Messier 22, the constellation about 10,000 light-years from Earth. Each black hole has 10 to 20 times the mass of the sun, Telegraph reported.

The region in space has a gravitational field so strong that all forms of matter, including light, cannot escape its boundary, called black holes. They are the remains of super-massive stars that have "died" by collapsing themselves inside. For years astronomers believed that each constellation contained only one black hole. So new discoveries can lead to a hypothetical review of the existence of black holes in every constellation.

"Our findings show that all hypotheses and models need to be adjusted," said James Miller-Jones, a member of the research team.

The team has modeled to reproduce the evolution of the Messier constellation 22. The model shows that many black holes formed during its evolution. Thus, the pair of black holes the team has just discovered is not the only black hole in this constellation.

"Messier 22 can hold up to 100 black holes, but we can only find them if they swallow the stars," Miller-Jones said.
