Story summary

Astronomers mapped cold gas around Sagittarius A* (Sgr A*) with ALMA, revealing a cone-shaped gap where cold gas is absent.
The cone-shaped gap indicates Sgr A* is emitting powerful winds that shape its surroundings.
The study provides evidence of a current wind from Sgr A*, whose immense energy challenges previous assumptions about gas behavior near black holes.
