IC 3093

IC 3093 is a spiral galaxy in the constellation Coma Berenices about 328 million ly from Earth. It spans roughly 35,000 ly, about 35% of our Milky Way's width. The light reaching us tonight left it about 328 million years ago.

Because its light is 328 million ly from home, you are seeing IC 3093 as it looked roughly 328 million years ago. The photons left before that much of history had passed, and are only now reaching us. This distance is estimated from the galaxy's redshift, so the lookback time is approximate.
