IC 777

IC 777

IC 777 is a barred spiral galaxy in the constellation Coma Berenices about 120 million ly from Earth. It spans roughly 29,000 ly, about 29% of our Milky Way's width. It is receding from us at about 2,556 km/s.

Because its light is 120 million ly from home, you are seeing IC 777 as it looked roughly 120 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.
