IC 3862

IC 3862 is a spiral galaxy in the constellation Canes Venatici about 203 million ly from Earth. It spans roughly 51,000 ly, about 51% of our Milky Way's width. The light reaching us tonight left it about 203 million years ago.

Because its light is 203 million ly from home, you are seeing IC 3862 as it looked roughly 203 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.
