NGC 7724

NGC 7724

NGC 7724 is a barred spiral galaxy in the constellation Aquarius about 89 million ly from Earth. It spans roughly 38,000 ly, about 38% of our Milky Way's width. It is receding from us at about 1,682 km/s.

Because its light is 89 million ly from home, you are seeing NGC 7724 as it looked roughly 89 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.
