Our Night Sky In The Future

July 31st 2012 02:41
NASA astronomers announced in June 2012 they are certain that our galaxy is on an unavoidable collision course with the Andromeda Galaxy, the closest spiral galaxy to us. Donít worry though, it wonít be happening for another 3.5 billion years or so. Whatís interesting is that the collision will drastically change what our night sky looks like, and the astronomers released a series of photo illustrations showing what future astrophotographers will be shooting when they point their cameras at the heavens.

night sky of the future
In about 3.75 billion years, Andromeda will be close enough to us that it begins to dominate the night sky

galaxy collision in our skies
As the galaxies collide, the sky will be filled with 'star fireworks' ó the formation of new stars

andromeda galaxy collision with the milky way
In 4 billion years, the two galaxies will begin warping one another, causing them to have a funhouse mirror look in the sky

Our new galaxy of the future. 7 billion years

At about 7 billion years, things will begin settling down. The two galaxies will form a new giant elliptical galaxy, with a single bright core filling up our night time sky.
