IC 2556

IC 2556 is a spiral galaxy in the constellation Antlia about 117 million ly from Earth. It spans roughly 62,000 ly, about 62% of our Milky Way's width. It is receding from us at about 2,351 km/s.

Because its light is 117 million ly from home, you are seeing IC 2556 as it looked roughly 117 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.
