NGC 5311

NGC 5311 is a lenticular galaxy in the constellation Canes Venatici about 125 million ly from Earth. It spans roughly 73,000 ly, about 73% of our Milky Way's width. It is receding from us at about 2,698 km/s.

Because its light is 125 million ly from home, you are seeing NGC 5311 as it looked roughly 125 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.
