NGC 4164

NGC 4164 is an elliptical galaxy in the constellation Virgo about 906 million ly from Earth. It spans roughly 190,000 ly, about 1.9 times the width of our Milky Way. The light reaching us tonight left it about 906 million years ago.

Because its light is 906 million ly from home, you are seeing NGC 4164 as it looked roughly 906 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.
