NGC 4889

NGC 4889 is an elliptical galaxy in the constellation Coma Berenices about 300 million ly from Earth. It spans roughly 230,000 ly, about 2.3 times the width of our Milky Way. It is receding from us at about 6,494 km/s.

Because its light is 300 million ly from home, you are seeing NGC 4889 as it looked roughly 300 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.
