For now, only a few dozen black holes have been found in our galaxy, although there are probably hundreds of millions of them out here. As part of the space mission Gaia, Polish astronomers have now revealed the secrets hidden by a pair of invisible stars and proved that they had a good method of looking for black holes in the Milky Way.
The European Space Agency`s OPS-SAT satellite has been in orbit since Wednesday. The mission`s goal is to test the satellite`s innovative onboard systems and mission control methods in space conditions. Specialists from the Polish company Creotech Instruments SA contributed to the work on the satellite.
