NGC 6621
NGC 6621 is a barred spiral galaxy in the constellation Draco about 277 million ly from Earth. It spans roughly 170,000 ly, about 1.7 times the width of our Milky Way. It is receding from us at about 6,210 km/s.

Because its light is 277 million ly from home, you are seeing NGC 6621 as it looked roughly 277 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.
