NGC 1568

NGC 1568 is a lenticular galaxy in the constellation Eridanus about 221 million ly from Earth. It spans roughly 94,000 ly, about the width of our Milky Way. The light reaching us tonight left it about 221 million years ago.

Because its light is 221 million ly from home, you are seeing NGC 1568 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.
