IC 2798
IC 2798 is a spiral galaxy in the constellation Leo about 558 million ly from Earth. It spans roughly 120,000 ly, about the width of our Milky Way. The light reaching us tonight left it about 558 million years ago.

Because its light is 558 million ly from home, you are seeing IC 2798 as it looked roughly 558 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.
