IC 2378

IC 2378 is an elliptical galaxy in the constellation Cancer about 703 million ly from Earth. It spans roughly 270,000 ly, about 2.7 times the width of our Milky Way. It is receding from us at about 14,830 km/s.

Because its light is 703 million ly from home, you are seeing IC 2378 as it looked roughly 703 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.
