NGC 1206

NGC 1206 is an elliptical galaxy in the constellation Eridanus about 486 million ly from Earth. It spans roughly 110,000 ly, about the width of our Milky Way. The light reaching us tonight left it about 486 million years ago.

Because its light is 486 million ly from home, you are seeing NGC 1206 as it looked roughly 486 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.
