Galactic core expels cosmic winds, revealing a colossal cone-shaped void

A colossal cone-shaped void has been detected near Sagittarius A*, confirming galactic core expels powerful cosmic winds for the first time. This discovery provides the first potential evidence that the supermassive black hole at our galaxy's center violently interacts with its surroundings, answering a 50-year astronomical puzzle. Researchers used ALMA telescope data, suppressing the black hole's radio brightness to visualize the void, which has been active for at least 20,000 years.
