Observation of two galaxies by Hubble
Usually in space, galaxies collide and are drawn along highways of dark matter towards the nodes of the galaxy cluster, where they flow towards a mutual galactic center. But how do you know that these two galaxies are not merging?
Hubble images show that these two galaxies and their surroundings are very clean and dust-free, while a collision would disturb their peace and leave a lot of dust and star clusters. Also, examining the distance and light of the two galaxies also shows that they are millions of light years apart.
