NGC 4623

NGC 4623 is a lenticular galaxy in the constellation Virgo about 85 million ly from Earth. It spans roughly 55,000 ly, about 55% of our Milky Way's width. It is receding from us at about 1,841 km/s.

Because its light is 85 million ly from home, you are seeing NGC 4623 as it looked roughly 85 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.
