NGC 4893A

NGC 4893A is an elliptical galaxy in the constellation Canes Venatici about 499 million ly from Earth. It spans roughly 81,000 ly, about 81% of our Milky Way's width. The light reaching us tonight left it about 499 million years ago.

Because its light is 499 million ly from home, you are seeing NGC 4893A as it looked roughly 499 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.
