NGC 4822

NGC 4822 is an elliptical galaxy in the constellation Virgo about 184 million ly from Earth. It spans roughly 74,000 ly, about 74% of our Milky Way's width. The light reaching us tonight left it about 184 million years ago.

Because its light is 184 million ly from home, you are seeing NGC 4822 as it looked roughly 184 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.
