Strange objects found orbiting Milky Way's black hole

At the center of the Milky Way, there's a gigantic black hole, Sagittarius A* (Sgr A*). Scientists earlier saw 2 mysterious objects in the black hole's cosmic neighborhood which are orbiting the black hole. They were named G1 and G2. In a new study, four more of these strange gas cloud-like objects have been identified which seem similar to G1 and G2. Experts suggest they are members of new class of cosmic phenomena.
