NGC 2576

NGC 2576 is a spiral galaxy in the constellation Cancer about 390 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 390 million years ago.

Because its light is 390 million ly from home, you are seeing NGC 2576 as it looked roughly 390 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.
