NASA images show the view from the earth when galaxies collide



  • The Milky Way is well on its way to colliding and growing together with its nearest neighbor, the Andromeda Galaxy, in about 4 billion years
  • NASA images show what the arrival of an entire galaxy of stars will look like.
  • While Andromeda's approach to the night sky produces a bright and spectacular picture, life on Earth is unlikely to be seen. Until then, the sun is swollen over the orbit of Venus and charred the earth.

The nearby galaxy Andromeda is racing toward us at 250,000 miles per hour. It has a long way to go ̵

1; about 2.5 million light-years – but it will probably break into the Milky Way in about 4 billion years.

When the galaxies meet, it will make for a beautiful sight. As we approach, the Andromeda galaxy will pull the ribbon of the Milky Way across our skies. Finally, the nuclei of the galaxies merge.

Unfortunately, life as we know it will not exist on Earth while this spectacle is going on. Until then, the sun will run out of fuel, causing it to expand into the orbit of Venus. This will make the earth about as hot as Mercury.

However, NASA has created step-by-step mappings depicting what the future views of the night sky would look like when the galaxies collide with Andromeda and the Milky Way galaxy.
