NGC 6003

NGC 6003 is a lenticular galaxy in the constellation Serpens about 189 million ly from Earth. It spans roughly 53,000 ly, about 53% of our Milky Way's width. It is receding from us at about 4,059 km/s.

Because its light is 189 million ly from home, you are seeing NGC 6003 as it looked roughly 189 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.
