NGC 7307

NGC 7307 is a spiral galaxy in the constellation Grus about 98 million ly from Earth. It spans roughly 110,000 ly, about the width of our Milky Way. It is receding from us at about 1,850 km/s.

Because its light is 98 million ly from home, you are seeing NGC 7307 as it looked roughly 98 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.
