NGC 203

NGC 203

NGC 203 is a lenticular galaxy in the constellation Pisces about 245 million ly from Earth. It spans roughly 70,000 ly, about 70% of our Milky Way's width. The light reaching us tonight left it about 245 million years ago.

Because its light is 245 million ly from home, you are seeing NGC 203 as it looked roughly 245 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.
