NGC 772

NGC 772

NGC 772 is a barred spiral galaxy in the constellation Aries about 116 million ly from Earth. It spans roughly 150,000 ly, about 1.5 times the width of our Milky Way. It is receding from us at about 2,454 km/s.

Because its light is 116 million ly from home, you are seeing NGC 772 as it looked roughly 116 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.
