IC 1313

IC 1313 is a spiral galaxy in the constellation Capricornus about 155 million ly from Earth. It spans roughly 72,000 ly, about 72% of our Milky Way's width. It is receding from us at about 3,175 km/s.

Because its light is 155 million ly from home, you are seeing IC 1313 as it looked roughly 155 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.
