NGC 4199A

NGC 4199A is an elliptical galaxy in the constellation Ursa Major about 839 million ly from Earth. It spans roughly 250,000 ly, about 2.5 times the width of our Milky Way. The light reaching us tonight left it about 839 million years ago.

Because its light is 839 million ly from home, you are seeing NGC 4199A as it looked roughly 839 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.
