NGC 7807

NGC 7807 is a barred spiral galaxy in the constellation Cetus about 357 million ly from Earth. It spans roughly 76,000 ly, about 76% of our Milky Way's width. The light reaching us tonight left it about 357 million years ago.

Because its light is 357 million ly from home, you are seeing NGC 7807 as it looked roughly 357 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.
