Astronomers have discovered evidence of a cosmic wind emanating from Sagittarius A*, the supermassive black hole at the center of our Milky Way.
The finding, published in The Astrophysical Journal Letters, could explain why this particular black hole has remained so quiet for over five decades. The study was led by Mark Gorski, a research assistant professor at Northwestern University in Evanston, Illinois, and Lena Murchikova, an assistant professor of physics and astronomy at Northwestern.
