IC 5075

IC 5075 is a spiral galaxy in the constellation Pavo about 617 million ly from Earth. It spans roughly 200,000 ly, about 2.0 times the width of our Milky Way. The light reaching us tonight left it about 617 million years ago.

Because its light is 617 million ly from home, you are seeing IC 5075 as it looked roughly 617 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.
