NGC 1368

NGC 1368 is a lenticular galaxy in the constellation Eridanus about 448 million ly from Earth. It spans roughly 150,000 ly, about the width of our Milky Way. The light reaching us tonight left it about 448 million years ago.

Because its light is 448 million ly from home, you are seeing NGC 1368 as it looked roughly 448 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.
