NGC 3876

NGC 3876 is a spiral galaxy in the constellation Virgo about 133 million ly from Earth. It spans roughly 43,000 ly, about 43% of our Milky Way's width. The light reaching us tonight left it about 133 million years ago.

Because its light is 133 million ly from home, you are seeing NGC 3876 as it looked roughly 133 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.
