IC 665
IC 665
IC 665 is a spiral galaxy in the constellation Crater about 214 million ly from Earth. It spans roughly 64,000 ly, about 64% of our Milky Way's width. The light reaching us tonight left it about 214 million years ago.

Because its light is 214 million ly from home, you are seeing IC 665 as it looked roughly 214 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.
