NGC 311

NGC 311 is a lenticular galaxy in the constellation Pisces about 236 million ly from Earth. It spans roughly 93,000 ly, about the width of our Milky Way. It is receding from us at about 5,062 km/s.

Because its light is 236 million ly from home, you are seeing NGC 311 as it looked roughly 236 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.
