IC 3118

IC 3118 is an irregular galaxy in the constellation Virgo about 81 million ly from Earth. It spans roughly 30,000 ly, about 30% of our Milky Way's width. The light reaching us tonight left it about 81 million years ago.

Because its light is 81 million ly from home, you are seeing IC 3118 as it looked roughly 81 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.
