IC 4774

IC 4774 is a barred spiral galaxy in the constellation Pavo about 524 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 524 million years ago.

Because its light is 524 million ly from home, you are seeing IC 4774 as it looked roughly 524 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.
