The Esa Gaia spacecraft has discovered two black holes in close proximity to Earth. And the great thing is that this is not the only thing that makes them special, as they seem to be very different from others that have been observed before. Named Gaia BH1 and Gaia BH2, their biggest difference from other black holes is their distance from their companion star, according to the European Space Agency.
Binary systems consisting of a black hole and a star are quite common. Many of these have already been discovered, but they are usually so close that the black hole is continuously consuming material that it steals from the star, generating enormous amounts of energy in the process. It was confirmed that, although the detected objects are black holes, they practically do not carry away material from the star. So they are special in many ways.
These two black holes are 1560 and 3800 light years away from Earth. This may seem like a huge distance, but if we take into account that the nearest one discovered so far is 1011 light-years from the solar system and that our galaxy spans 105,000 light-years, we can get an idea of how far they close.
