IC 4125

IC 4125 is an elliptical galaxy in the constellation Coma Berenices about 942 million ly from Earth. It spans roughly 280,000 ly, about 2.8 times the width of our Milky Way. The light reaching us tonight left it about 942 million years ago.

Because its light is 942 million ly from home, you are seeing IC 4125 as it looked roughly 942 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.
