NGC 703

NGC 703

NGC 703 is an elliptical galaxy in the constellation Andromeda about 261 million ly from Earth. It spans roughly 75,000 ly, about 75% of our Milky Way's width. It is receding from us at about 4,752 km/s.

Because its light is 261 million ly from home, you are seeing NGC 703 as it looked roughly 261 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.
