Black hole at center of Milky Way might be windy
Astronomers using ALMA radio telescopes have discovered evidence of a cosmic wind emanating from Sagittarius A*, the supermassive black hole at the center of the Milky Way. This finding suggests the black hole is expelling hot gas, which may explain its relative inactivity over the past five decades.
Why it matters
Understanding the mechanics of supermassive black holes helps scientists comprehend how galaxies evolve and how black holes regulate their surrounding environments.
