NGC 2556

NGC 2556 is an elliptical galaxy in the constellation Cancer about 214 million ly from Earth. It spans roughly 39,000 ly, about 39% of our Milky Way's width. It is receding from us at about 4,635 km/s.

Because its light is 214 million ly from home, you are seeing NGC 2556 as it looked roughly 214 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.
