NGC 5583

NGC 5583 is an elliptical galaxy in the constellation Boötes about 234 million ly from Earth. It spans roughly 57,000 ly, about 57% of our Milky Way's width. It is receding from us at about 5,007 km/s.

Because its light is 234 million ly from home, you are seeing NGC 5583 as it looked roughly 234 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.
