NGC 4970

NGC 4970 is a lenticular galaxy in the constellation Hydra about 151 million ly from Earth. It spans roughly 79,000 ly, about 79% of our Milky Way's width. It is receding from us at about 3,255 km/s.

Because its light is 151 million ly from home, you are seeing NGC 4970 as it looked roughly 151 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.
