IC 4368

IC 4368 is a lenticular galaxy in the constellation Virgo about 522 million ly from Earth. It spans roughly 83,000 ly, about 83% of our Milky Way's width. The light reaching us tonight left it about 522 million years ago.

Because its light is 522 million ly from home, you are seeing IC 4368 as it looked roughly 522 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.
