Astronomers found Mysterious gaseous objects in the centre of our galaxy

Astronomers have observed strange gas-like objects close to a large black hole in the centre of our Milky Way. This is a discovery that can further expand our understanding of the forces that make up stars and other celestial bodies in the universe.

Andrea Ghez of the University of California, Los Angeles in the US said, “These objects look gaseous, but in practice, they are like stars.” According to a study published in the journal Nature, new objects appear in groups most of the time and seem to drag them outward when their orbit draws them closest to a dense black hole. These objects take about 100 to 1,000 years to complete their orbit around a black hole called Sagittarius A.

Ghez said that we had seen it before, but it didn’t look so strange then. When it got closer to the black hole, it got longer and it’s gas leaked out and merged into the black hole, but now it is away from the black hole, it is back to its precursor.

Special signature
In previous research astronomers identified two unusual objects at the centre of the Milky Way, which they named G1 and G2, and were collectively named the G-object. They believe that G2 could be two stars orbiting a black hole in tandem and merged into a larger star, which was covered in thick gas and dust. On continuously monitoring the G2, astronomers found that it also has a special type of signature, which makes it easy to identify.
