There's a lot out there in the universe that we don't really understand but is still incredible to behold.
The Hubble Space Telescope just captured on such event; an image of two galaxies colliding millions of light-years away, resulting in a dazzling spectacle.
The image captured shows a point in space about 230 million light-years away from Earth, in the constellation Hercules. The Hubble Space Telescope zoomed in there on something called NGC 6052, a pair of extremely bright galaxies being smushed together.

This phenomenon was discovered in 1784 by William Herschel, who at the time thought it was a single galaxy with a weird shape. Years later we realised it's in fact two of them twerking up against each other.
Years ago, the gravity fields in the constellation forced the two galaxies together to form NGC 6052. Stars from the original two galaxies have since had their trajectories shifted, and consequently now experience different gravitational pulls as well. None of these stars will actually hit each other however, because they're really small compared to the vast amounts of space between them. The galaxies however, will eventually merge into a single galaxy with a more traditional shape.

The study of NGC 6052 gives scientists and idea of what future galaxy mergers will look like. Our own Milky Way for instance will also one day collide with the nearby Andromeda galaxy, a billions of years from now.
It's a good thing then we don't navigate just by the stars anymore.
