NGC 765

NGC 765

NGC 765 is a spiral galaxy in the constellation Aries about 238 million ly from Earth. It spans roughly 180,000 ly, about 1.8 times the width of our Milky Way. It is receding from us at about 5,117 km/s.

Because its light is 238 million ly from home, you are seeing NGC 765 as it looked roughly 238 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.
