A study carried out at the University of Durham in the United Kingdom revealed that a galaxy is approaching the Milky Way, the collision would end life on Earth and the consequences of the impact would awaken a black hole.
The Great Magellanic Cloud, one of the satellite galaxies orbiting around the Milky Way, would collide with it.
Scientists have determined that the satellite is almost twice as dark as expected and predicts that it will affect our galaxy within 2 billion years. Previously, it was believed that a similar phenomenon would occur within 8 million years.
Lead author Marius Cautun said the collision of the Great Magellanic Cloud with the Milky Way would "awaken a black hole that would transform our galaxy into an active galactic nucleus."
He added: "This phenomenon will generate high energy radiation, the black hole will devour the circulating gas, increase its size and push the solar system out of the Milky Way."
