NGC 4949

NGC 4949 is a barred spiral galaxy in the constellation Coma Berenices about 318 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 318 million years ago.

Because its light is 318 million ly from home, you are seeing NGC 4949 as it looked roughly 318 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.
