"Galactic Collision Reveals Earth's Closest Supermassive Black Hole Pair"

Astronomers have discovered a pair of supermassive black holes in the aftermath of a galactic collision that occurred around a billion years ago. Located 90 million light-years away, these black holes have masses of 154 million and 6.3 million times that of the sun. They are currently orbiting each other and will eventually merge, creating an even stronger supermassive black hole. The discovery provides insight into the future collision between the Milky Way and Andromeda galaxies. The chaotic state of the galaxy NGC 7727, resulting from the collision, offers a glimpse of what our own galaxy will look like in 4.5 billion years.
