When Galaxies Collide: These are some astonishing pictures that makes me wish I could go back in time and choose to be an astronomer like I dreamt of when I was 13. Some of the numbers are mindboggling – galaxies 450 million light years away, a 100,000 light years across… and we get to see them from our infinitesimally small spec in the universe. How could we have the hubris that this was created solely for human? Simply amazing.
