NGC 5405

NGC 5405 is a spiral galaxy in the constellation Boötes about 321 million ly from Earth. It spans roughly 78,000 ly, about 78% of our Milky Way's width. It is receding from us at about 6,922 km/s.

Because its light is 321 million ly from home, you are seeing NGC 5405 as it looked roughly 321 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.
