NGC 4599

NGC 4599 is a lenticular galaxy in the constellation Virgo about 87 million ly from Earth. It spans roughly 43,000 ly, about 43% of our Milky Way's width. It is receding from us at about 1,878 km/s.

Because its light is 87 million ly from home, you are seeing NGC 4599 as it looked roughly 87 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.
