IC 1143

IC 1143 is an elliptical galaxy in the constellation Ursa Minor about 303 million ly from Earth. It spans roughly 130,000 ly, about the width of our Milky Way. It is receding from us at about 6,395 km/s.

Because its light is 303 million ly from home, you are seeing IC 1143 as it looked roughly 303 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.
