NGC 365

NGC 365

NGC 365 is a barred spiral galaxy in the constellation Sculptor about 465 million ly from Earth. It spans roughly 140,000 ly, about the width of our Milky Way. The light reaching us tonight left it about 465 million years ago.

Because its light is 465 million ly from home, you are seeing NGC 365 as it looked roughly 465 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.
