IC 4340

IC 4340 is an elliptical galaxy in the constellation Canes Venatici about 348 million ly from Earth. It spans roughly 130,000 ly, about the width of our Milky Way. It is receding from us at about 7,526 km/s.

Because its light is 348 million ly from home, you are seeing IC 4340 as it looked roughly 348 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.
