NGC 4976

NGC 4976 is an elliptical galaxy in the constellation Centaurus about 66 million ly from Earth. It spans roughly 110,000 ly, about the width of our Milky Way. It is receding from us at about 1,453 km/s.

Because its light is 66 million ly from home, you are seeing NGC 4976 as it looked roughly 66 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.
