NGC 3156

NGC 3156 is a lenticular galaxy in the constellation Sextans about 62 million ly from Earth. It spans roughly 35,000 ly, about 35% of our Milky Way's width. It is receding from us at about 1,118 km/s.

Because its light is 62 million ly from home, you are seeing NGC 3156 as it looked roughly 62 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.
