IC 2738

IC 2738 is an elliptical galaxy in the constellation Ursa Major about 507 million ly from Earth. It spans roughly 130,000 ly, about the width of our Milky Way. It is receding from us at about 10,450 km/s.

Because its light is 507 million ly from home, you are seeing IC 2738 as it looked roughly 507 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.
