NGC 7288

NGC 7288 is a spiral galaxy in the constellation Aquarius about 229 million ly from Earth. It spans roughly 130,000 ly, about the width of our Milky Way. It is receding from us at about 4,807 km/s.

Because its light is 229 million ly from home, you are seeing NGC 7288 as it looked roughly 229 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.
