NGC 5691

NGC 5691

NGC 5691 is a spiral galaxy in the constellation Virgo about 88 million ly from Earth. It spans roughly 48,000 ly, about 48% of our Milky Way's width. It is receding from us at about 1,846 km/s.

Because its light is 88 million ly from home, you are seeing NGC 5691 as it looked roughly 88 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.
