NGC 4847

NGC 4847 is an elliptical galaxy in the constellation Virgo about 226 million ly from Earth. It spans roughly 55,000 ly, about 55% of our Milky Way's width. The light reaching us tonight left it about 226 million years ago.

Because its light is 226 million ly from home, you are seeing NGC 4847 as it looked roughly 226 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.
