IC 2552

IC 2552 is an elliptical galaxy in the constellation Antlia about 143 million ly from Earth. It spans roughly 78,000 ly, about 78% of our Milky Way's width. It is receding from us at about 3,104 km/s.

Because its light is 143 million ly from home, you are seeing IC 2552 as it looked roughly 143 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.
