NGC 3250C

NGC 3250C is a spiral galaxy in the constellation Antlia about 120 million ly from Earth. It spans roughly 67,000 ly, about 67% of our Milky Way's width. The light reaching us tonight left it about 120 million years ago.

Because its light is 120 million ly from home, you are seeing NGC 3250C as it looked roughly 120 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.
