NGC 2573B

NGC 2573B is an irregular galaxy in the constellation Octans about 118 million ly from Earth. It spans roughly 39,000 ly, about 39% of our Milky Way's width. The light reaching us tonight left it about 118 million years ago.

Because its light is 118 million ly from home, you are seeing NGC 2573B as it looked roughly 118 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.
