IC 2941

IC 2941 is a barred spiral galaxy in the constellation Leo about 289 million ly from Earth. It spans roughly 71,000 ly, about 71% of our Milky Way's width. The light reaching us tonight left it about 289 million years ago.

Because its light is 289 million ly from home, you are seeing IC 2941 as it looked roughly 289 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.
