NGC 2840
NGC 2840 is a barred spiral galaxy in the constellation Lynx about 349 million ly from Earth. It spans roughly 110,000 ly, about the width of our Milky Way. It is receding from us at about 7,477 km/s.

Because its light is 349 million ly from home, you are seeing NGC 2840 as it looked roughly 349 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.
