APOD: The Antennae Galaxies in Collision

Two galaxies have recently been spotted colliding in the far off constellation of Corvus. it is recognized that these galaxies may be "colliding", however the stars that are held in the galaxy rarely collide due to the insignificance of them compared to the entirety of the galaxy, which is mainly made up of dust, gas and debris. This may look like it is happening fast, however this merging will take hundreds of years to show any significant differences from what we see now. However, the collision is causing the rapid birth of millions of stars in these galaxies, meaning new things could be forming for our eyes to see.
