Scientists found something peculiar coming from the center of the Milky Way galaxy: a previously-unnoticed signal they think is coming from the supermassive black hole at the heart of our galaxy.

The team of Keio University researchers think that the signal is caused when the accretion disk around the black hole flares up and gives off extremely rapidly-rotating radio spots, according to research published last month in The Astrophysical Journal Letters - providing a glimpse at the unimaginable chaos at the core of our galaxy.

The flickering signals aren't entirely new - scientists have previously discovered larger and slower flare ups.
