NGC 3203

NGC 3203

NGC 3203 is a lenticular galaxy in the constellation Hydra about 112 million ly from Earth. It spans roughly 100,000 ly, about the width of our Milky Way. It is receding from us at about 2,394 km/s.

Because its light is 112 million ly from home, you are seeing NGC 3203 as it looked roughly 112 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.
