NGC 5010

NGC 5010 is a lenticular galaxy in the constellation Virgo about 138 million ly from Earth. It spans roughly 40,000 ly, about 40% of our Milky Way's width. It is receding from us at about 6,400 km/s.

Because its light is 138 million ly from home, you are seeing NGC 5010 as it looked roughly 138 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.
