NGC 6213

NGC 6213 is a galaxy in the constellation Draco about 251 million ly from Earth. It spans roughly 50,000 ly, about 50% of our Milky Way's width. The light reaching us tonight left it about 251 million years ago.

Because its light is 251 million ly from home, you are seeing NGC 6213 as it looked roughly 251 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.
