A great galaxy mashup will occur in 6 billion years when our galaxy, the Milky Way, collides with the nearby Andromeda galaxy, according to the first reliable determination of Andromeda’s sideways motion, made using NASA’s Hubble Space Telescope.
The galactic union isn’t expected to result in the destruction of Earth, the Sun, or any other planet in the solar system. In fact, no stars whatsoever are expected to collide becauase they are so far apart within each system. But Earth’s night sky is expected to undergo a “spectacular evolution,” according to NASA scientists, who gave a press conference on the new findings on Thursday.
