IC 3829

IC 3829 is a lenticular galaxy in the constellation Hydra about 133 million ly from Earth. It spans roughly 130,000 ly, about the width of our Milky Way. It is receding from us at about 3,612 km/s.

Because its light is 133 million ly from home, you are seeing IC 3829 as it looked roughly 133 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.
