IC 624

IC 624 is a spiral galaxy in the constellation Sextans about 226 million ly from Earth. It spans roughly 160,000 ly, about 1.6 times the width of our Milky Way. The light reaching us tonight left it about 226 million years ago.

Because its light is 226 million ly from home, you are seeing IC 624 as it looked roughly 226 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.
