Astronomers predict that Earth will be besieged during the largest galactic event in its history. The two giant galaxies will collide with each other, after 3.7 billion years.
Experts believe that the Earth will - fortunately - survive the collision, although it will be affected.
The collision will appear directly in front of us, changing the shape of the sky at night to be different from anything a person has seen before.
Join our future journey to see how it will be:
Away from the city lights and on a clear night, this is how the earth looks like.
You can see - during certain times of the year - the Andromeda Galaxy - surrounded by a yellow ring at the bottom - next to the bright range of our Milky Way.
Andromeda now separates us from 2.5 million light-years away, and when they collide with our galaxy in less than 4 billion years, a catastrophe that will last for billions of years will befall them, tearing them apart to form a new galaxy.
And the creatures that live on Earth just before the collision will have a very beautiful view.
On the left, you see Andromeda as you approach the Milky Way driven by the forces of mutual attraction.
The two galaxies will be affected by the collision quickly, after only 250 years after the collision, only the ruins of what was once galaxies will remain.
but that is not all.
The battle will last billions of years until the two black holes in their core approach close together.
One billion years after the cosmic massacre, the night sky will be blazing at the glow of the new elliptical center of the galaxy - if the Earth were present then the sun would swallow it up a billion years from now.
Because galaxy fusion takes billions of years, astronomers comb the sky in search of different phases of epic battles.
Below is a photo was taken by the Hubble Telescope of two spiral galaxies in an early merger phase.
This is a different set of galaxies, one of which has been stretched and distorted by the attractiveness of the other galaxies.
