NGC 4899

NGC 4899 is a spiral galaxy in the constellation Virgo about 124 million ly from Earth. It spans roughly 73,000 ly, about 73% of our Milky Way's width. It is receding from us at about 2,623 km/s.

Because its light is 124 million ly from home, you are seeing NGC 4899 as it looked roughly 124 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.
