NGC 1583

NGC 1583 is an elliptical galaxy in the constellation Eridanus about 414 million ly from Earth. It spans roughly 130,000 ly, about the width of our Milky Way. The light reaching us tonight left it about 414 million years ago.

Because its light is 414 million ly from home, you are seeing NGC 1583 as it looked roughly 414 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.
