NGC 4519

NGC 4519 is a spiral galaxy in the constellation Virgo about 56 million ly from Earth. It spans roughly 38,000 ly, about 38% of our Milky Way's width. It is receding from us at about 1,180 km/s.

Because its light is 56 million ly from home, you are seeing NGC 4519 as it looked roughly 56 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.
