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

3 articles · Updated · Radar Armenia · Jun 15

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.

Insights

Our galaxy's black hole has a 'gentle breeze.' Are countless other quiet galaxies being secretly reshaped by similar winds?
If black holes are cosmic vacuums, why is ours blowing a powerful wind that shapes our galaxy?
