NGC 1603

NGC 1603 is a lenticular galaxy in the constellation Eridanus about 241 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 5,117 km/s.

Because its light is 241 million ly from home, you are seeing NGC 1603 as it looked roughly 241 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.
