IC 723

IC 723 is an irregular galaxy in the constellation Crater about 145 million ly from Earth. It spans roughly 34,000 ly, about 34% of our Milky Way's width. The light reaching us tonight left it about 145 million years ago.

Because its light is 145 million ly from home, you are seeing IC 723 as it looked roughly 145 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.
