IC 3005

IC 3005

IC 3005 is a barred spiral galaxy in the constellation Hydra about 80 million ly from Earth. It spans roughly 57,000 ly, about 57% of our Milky Way's width. It is receding from us at about 1,781 km/s.

Because its light is 80 million ly from home, you are seeing IC 3005 as it looked roughly 80 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.
