NGC 3707

NGC 3707 is an elliptical galaxy in the constellation Crater about 248 million ly from Earth. It spans roughly 48,000 ly, about 48% of our Milky Way's width. The light reaching us tonight left it about 248 million years ago.

Because its light is 248 million ly from home, you are seeing NGC 3707 as it looked roughly 248 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.
