What to know about Scientific Validation

Astrophysicists from Northwestern University have identified evidence of a powerful wind emanating from Sagittarius A*, the supermassive black hole at the center of the Milky Way. By using ALMA radio telescope data and X-ray imagery from NASA's Chandra Observatory, the researchers discovered a cone-shaped cavity devoid of cold molecular gas, confirming theoretical predictions about black hole outflows.

What happened

Milky Way black hole's missing wind finally found after a half-century-long search Sadie Harley Scientific Editor Robert Egan Associate Editor The hunt is over.

Why it matters

After more than 50 years of searching, astrophysicists at Northwestern University have finally discovered evidence of a powerful wind blowing from the Milky Way's central supermassive black hole, Sagittarius A* (Sgr A*).

Common ground

According to theoretical physics and a long-accepted understanding of galaxies' evolution, as black holes consume materials, they should produce wind or jets.
