IC 5036

IC 5036 is a spiral galaxy in the constellation Indus about 161 million ly from Earth. It spans roughly 46,000 ly, about 46% of our Milky Way's width. The light reaching us tonight left it about 161 million years ago.

Because its light is 161 million ly from home, you are seeing IC 5036 as it looked roughly 161 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.
