IC 3824

IC 3824 is a lenticular galaxy in the constellation Corvus about 609 million ly from Earth. It spans roughly 200,000 ly, about 2.0 times the width of our Milky Way. The light reaching us tonight left it about 609 million years ago.

Because its light is 609 million ly from home, you are seeing IC 3824 as it looked roughly 609 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.
