IC 1801

IC 1801

IC 1801 is a barred spiral galaxy in the constellation Aries about 189 million ly from Earth. It spans roughly 65,000 ly, about 65% of our Milky Way's width. It is receding from us at about 4,023 km/s.

Because its light is 189 million ly from home, you are seeing IC 1801 as it looked roughly 189 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.
