NGC 1797

NGC 1797 is a barred spiral galaxy in the constellation Eridanus about 208 million ly from Earth. It spans roughly 72,000 ly, about 72% of our Milky Way's width. It is receding from us at about 4,441 km/s.

Because its light is 208 million ly from home, you are seeing NGC 1797 as it looked roughly 208 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.
