NGC 1390

NGC 1390 is a lenticular galaxy in the constellation Eridanus about 57 million ly from Earth. It spans roughly 24,000 ly, about 24% of our Milky Way's width. It is receding from us at about 1,215 km/s.

Because its light is 57 million ly from home, you are seeing NGC 1390 as it looked roughly 57 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.
