NGC 4447

NGC 4447 is a lenticular galaxy in the constellation Coma Berenices about 334 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 7,125 km/s.

Because its light is 334 million ly from home, you are seeing NGC 4447 as it looked roughly 334 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.
