IC 4255

IC 4255 is an elliptical galaxy in the constellation Hydra about 476 million ly from Earth. It spans roughly 190,000 ly, about 1.9 times the width of our Milky Way. It is receding from us at about 10,173 km/s.

Because its light is 476 million ly from home, you are seeing IC 4255 as it looked roughly 476 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.
