NGC 4510

NGC 4510 is an elliptical galaxy in the constellation Draco about 127 million ly from Earth. It spans roughly 54,000 ly, about 54% of our Milky Way's width. It is receding from us at about 2,732 km/s.

Because its light is 127 million ly from home, you are seeing NGC 4510 as it looked roughly 127 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.
