IC 293
IC 293
IC 293 is a lenticular galaxy in the constellation Perseus about 221 million ly from Earth. It spans roughly 68,000 ly, about 68% of our Milky Way's width. The light reaching us tonight left it about 221 million years ago.

Because its light is 221 million ly from home, you are seeing IC 293 as it looked roughly 221 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.
