Black Hole Wind Clears the Galactic Center ⚡ экспресс
Astronomers using the ALMA telescope have discovered a giant conical structure in the gas around the black hole at the center of the Milky Way. This 'funnel', over 3 light-years long, is carved by a hot wind sweeping away a cold molecular cloud. The discovery was made possible by record-breaking observational sensitivity: it's like seeing clear tracks left by an invisible vacuum cleaner in a fog.
In the center of our Galaxy lurks a black hole named Sagittarius A*. For decades, astronomers searched for its 'breath' — ejections of matter — but to no avail. Then the ALMA telescope spotted, in cold hydrogen, a giant cone-shaped cavity blown by the wind from the black hole. The scale is staggering: the cavity is over three light-years long, and the angle is almost 45 degrees.
The speed of this wind reaches tens of thousands of kilometers per second.
Now it’s clear how black holes run the show in galaxies: they don’t just devour matter, they also dictate where new worlds can emerge.
🎯 Although black holes are famous for sucking everything in, they can also 'exhale' — flinging matter out as hot wind.
