For the first time, scientists have seen the supermassive black hole at the Milky Way’s heart unleashing a hot wind.

Abstract

At the center of our Galaxy lies a supermassive black hole. Scientists have discovered that it 'blows out' a huge cone in the surrounding gas cloud, like a hairdryer pushing aside fluff. This discovery helps us understand how black holes affect their galaxies. What else might the heart of the Milky Way be hiding?

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.

For comparison: the fastest hurricane on Earth is a thousand times slower. Such a gale-force wind can 'snuff out' newborn stars — literally scatter the gas from which they form.

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.
