NGC 73
NGC 73 is a spiral galaxy in the constellation Cetus about 360 million ly from Earth. It spans roughly 180,000 ly, about 1.8 times the width of our Milky Way. The light reaching us tonight left it about 360 million years ago.

Because its light is 360 million ly from home, you are seeing NGC 73 as it looked roughly 360 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.
