NGC 868
NGC 868 is an elliptical galaxy in the constellation Cetus about 374 million ly from Earth. It spans roughly 86,000 ly, about the width of our Milky Way. The light reaching us tonight left it about 374 million years ago.

Because its light is 374 million ly from home, you are seeing NGC 868 as it looked roughly 374 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.
