Sagittarius A* Ejects Powerful Cosmic Wind After 50 Years of Eluding Detection

Summary
Northwestern University scientists reported that Sagittarius A*, the Milky Way’s central supermassive black hole, is ejecting matter in a powerful active wind from the Galaxy’s core.
More than 50 years of observations had failed to confirm such an outflow, making the finding the first clear detection of an active wind from the nearby black hole.
The team said the wind was observed in the central region around Sagittarius A*, which already emits radio, infrared and X-ray radiation and is surrounded by a hot gas cloud.
Scientists added that the outflow may not be unique: similar winds could be a common feature of many otherwise “quiet” galaxies across the Universe.
