IC 1724

IC 1724 is a lenticular galaxy in the constellation Sculptor about 178 million ly from Earth. It spans roughly 67,000 ly, about 67% of our Milky Way's width. It is receding from us at about 3,816 km/s.

Because its light is 178 million ly from home, you are seeing IC 1724 as it looked roughly 178 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.
