Scientists have made a groundbreaking discovery, detecting evidence of cosmic-scale wind coming from a supermassive black hole at the center of our galaxy, the Milky Way. The black hole, known as Sagittarius A*, has puzzled the scientific community for over 50 years due to its eerily quiet nature. Despite decades of searching, scientists could only gather clues of wind eruptions dating back more than 20,000 years but none more recent.

The Discovery

After five years of observations, researchers Mark Gorski and Lena Murchikova believe they have found signs of the missing wind. The duo created a highly detailed image of the black hole’s surrounding area, revealing a large, cone-shaped cavity devoid of cold gas. This feature could only have been sculpted by a wind of hot gas coming directly from the object itself.

The researchers used the Atacama Large Millimeter/Submillimeter Array (ALMA) radio telescopes in Chile to create the most detailed map ever of cold gas around Sagittarius A*. They then used NASA’s Chandra X-ray Observatory to confirm that the cold gas in the region was being sculpted by hot plasma, or electrically charged gas, coming from the galactic center.

Implications

The discovery of the wind’s presence is a significant breakthrough, as it helps scientists understand how supermassive black holes pump energy into their host galaxies and regulate their growth. The findings also provide new insights into the behavior of black holes, which are still not fully understood.

The researchers now plan to expand the map of cold gas to a larger region to diagnose the full impact of the wind. They also want to make a ‘movie’ of the gas approaching the black hole to observe how the clouds move and estimate how much of the gas the black hole consumes.
