NGC 4801

NGC 4801 is an elliptical galaxy in the constellation Ursa Major about 752 million ly from Earth. It spans roughly 300,000 ly, about 3.0 times the width of our Milky Way. The light reaching us tonight left it about 752 million years ago.

Because its light is 752 million ly from home, you are seeing NGC 4801 as it looked roughly 752 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.
