NGC 2505

NGC 2505 is a barred spiral galaxy in the constellation Lynx about 454 million ly from Earth. It spans roughly 160,000 ly, about 1.6 times the width of our Milky Way. The light reaching us tonight left it about 454 million years ago.

Because its light is 454 million ly from home, you are seeing NGC 2505 as it looked roughly 454 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.
