IC 3075

IC 3075 is a spiral galaxy in the constellation Coma Berenices about 299 million ly from Earth. It spans roughly 81,000 ly, about 81% of our Milky Way's width. The light reaching us tonight left it about 299 million years ago.

Because its light is 299 million ly from home, you are seeing IC 3075 as it looked roughly 299 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.
