A Colossal Cosmic Crash

If the majestic pinwheel structure of this galaxy wasn't beautiful enough, the pink halo seems to give this photograph a calm and magical feeling. But what we're actually seeing here is quite violent. In this picture, a galactic collision is taking place between the grand spiral galaxy and the tiny dwarf galaxy that you can see to its right. The pink mist is actually a huge cloud of gas, burning at millions of degrees Celsius, which forms when these galaxies clash!
