What you can see is the aftermath of a collision between two galaxies. The blue ring on the right was created when the white tail on the left passed through the original galaxy. Think of it like dropping a pebble in some water-- gravity draws the water inwards, which then clashes and ripples outwards again. This is the same principal, only on a ridiculously massive scale! When the white tail passed through the galaxy on the right, the gravity drew matter inwards, thus causing it to clash and ripple outward in a propagating density wave. Normally in these galactic rings, you'll see spikes of star formation due to the aggravated matter clashing together. I always say it, and I'll say it again, take a look guys... this is the future for the Milky Way! Also, It almost like a portal! Stargate anyone? ## Author Jaime is a freelance writer, who finds great joy in sharing the wonders of universe with others. She used this passion to launch "From Quarks to Quasars" in 2012.
