IC 3591

IC 3591 is an irregular galaxy in the constellation Virgo about 76 million ly from Earth. It spans roughly 18,000 ly, about 18% of our Milky Way's width. It is receding from us at about 1,896 km/s.

Because its light is 76 million ly from home, you are seeing IC 3591 as it looked roughly 76 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.
