NGC 6555

NGC 6555 is a spiral galaxy in the constellation Hercules about 104 million ly from Earth. It spans roughly 59,000 ly, about 59% of our Milky Way's width. It is receding from us at about 2,257 km/s.

Because its light is 104 million ly from home, you are seeing NGC 6555 as it looked roughly 104 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.
