Collisions between galaxies can sound both spectacular and rare. In fact, this phenomenon is very common, you know.
The galaxies in universe must have collided with other galaxies in the past. Likewise with the Milky Way in which we live today. Instead of being destroyed, two or more colliding galaxies merge into one giant galaxy.
Would you like to see the beauty behind the collision between galaxies? Come take a look at the following images from the Hubble Space Telescope!
1. NGC 3256 is the result of a collision between two galaxies that began 500 million years ago. This huge spiral galaxy is located south of the constellation Vela

2. The long tail of NGC 4676, known as the Rat Galaxy, is caused by the interaction of the gravitational forces of two colliding galaxies
3. The antenna galaxy is 60 million light years from Earth and was formed from the collision of NGC 4038 and NGC 4039 that began hundreds of millions of years ago
4. NGC 520 or known as Arp 157 is the result of two galaxies colliding in the direction of the Pisces constellation
5. This unique looking NGC 1316 is located in the constellation Fornax and has engulfed a small galaxy nearby

6. The interaction between Arp 273 (bottom) and UGC 1810 (top) is beautiful, isn’t it? For the next billion years, UGC 1810 will devour its companions and form a giant spiral galaxy
7. Portrait of an interesting attraction between two galaxies called Arp 87
8. Behind the beauty of NGC 6240 are three supermassive black holes, suggesting that three galaxies are colliding
9. Not just two or three galaxies, Arp 194 is a collision between clusters of galaxies
Actually at the moment galaksi bima sakti has started to interact with the Andromeda Galaxy. Both will create a huge galaxy called Milkomeda in about 5 billion years. Human civilization may or may not survive for about the next billion years, right?
