NGC 834

NGC 834

NGC 834 is a barred spiral galaxy in the constellation Andromeda about 218 million ly from Earth. It spans roughly 67,000 ly, about 67% of our Milky Way's width. It is receding from us at about 4,790 km/s.

Because its light is 218 million ly from home, you are seeing NGC 834 as it looked roughly 218 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.
