The Supermassive Black Hole at The Centre of Our Galaxy Is Becoming More Active

Sagittarius A*, the supermassive black hole at the centre of the Milky Way, isn't exactly rowdy. It's not classified as an active galactic nucleus - one of those galactic cores that glow exceedingly brightly as they feast on copious amounts of material from the surrounding space.

However, the brightness of our galaxy's centre does fluctuate a little across the electromagnetic spectrum on a daily basis. Astronomers have now confirmed that, over the last few years, Sgr A*'s most energetic X-ray flares have been increasing.
