NGC 7313

NGC 7313

NGC 7313 is a barred spiral galaxy in the constellation Piscis Austrinus about 268 million ly from Earth. It spans roughly 55,000 ly, about 55% of our Milky Way's width. The light reaching us tonight left it about 268 million years ago.

Because its light is 268 million ly from home, you are seeing NGC 7313 as it looked roughly 268 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.
