"Sagittarius A: Unveiling the Heart of the Milky Way"

The discovery of Sagittarius A*, the supermassive black hole at the center of the Milky Way, was made by astronomers using radio astronomy in the 1970s. Initially named Sagittarius A, it was later renamed Sagittarius A* due to its exciting nature. Over the years, observations of stars orbiting near Sagittarius A* confirmed its black-hole candidacy, and in 2022, the first image of the black hole was published, revealing a fuzzy reddish-orange accretion disk encircling a central blob of ethereal blackness.
