Astronomers have stumbled across a mystery at the heart of the Milky Way: A dense, cold gas shooting out of the region “like bullets.”
Researchers aren’t sure what the source of the gas is or how it’s being propelled so fast. They have previously observed flows of hot gas, but not cold gas which is harder to move due to it being heavier. The flow of cold gas could possibly be due to the supermassive black hole in the area or perhaps due to cosmic winds related to star formation.
“This is the first time something like this has been observed in our galaxy,” lead author Dr. Enrico Di Teodoro from Johns Hopkins University said in a statement. “We see these kind of processes happening in other galaxies. But, with external galaxies you get much more massive black holes, star formation activity is higher, it makes it easier for the
