IC 1562

IC 1562

IC 1562 is a barred spiral galaxy in the constellation Cetus about 177 million ly from Earth. It spans roughly 77,000 ly, about 77% of our Milky Way's width. It is receding from us at about 3,659 km/s.

Because its light is 177 million ly from home, you are seeing IC 1562 as it looked roughly 177 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.
