This is a pretty noisy pic I took of the Andromeda Galaxy, M31, about 2.5 million light years away. When photons of light from this galaxy started their journey to Earth, the Early Stone Age, or the Lower Paleolithic, was just getting started. She's surrounded by 14 satellite galaxies, two of which are easily visible here, M32 and M110.
