NGC 2857

NGC 2857 is a spiral galaxy in the constellation Ursa Major about 227 million ly from Earth. It spans roughly 120,000 ly, about the width of our Milky Way. It is receding from us at about 4,864 km/s.

Because its light is 227 million ly from home, you are seeing NGC 2857 as it looked roughly 227 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.
