IC 3927

IC 3927

IC 3927 is an elliptical galaxy in the constellation Hydra about 227 million ly from Earth. It spans roughly 85,000 ly, about the width of our Milky Way. It is receding from us at about 4,750 km/s.

Because its light is 227 million ly from home, you are seeing IC 3927 as it looked roughly 227 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.
