NGC 4053

NGC 4053 is a spiral galaxy in the constellation Coma Berenices about 338 million ly from Earth. It spans roughly 100,000 ly, about the width of our Milky Way. The light reaching us tonight left it about 338 million years ago.

Because its light is 338 million ly from home, you are seeing NGC 4053 as it looked roughly 338 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.
