IC 2593

IC 2593 is a lenticular galaxy in the constellation Hydra about 727 million ly from Earth. It spans roughly 180,000 ly, about 1.8 times the width of our Milky Way. The light reaching us tonight left it about 727 million years ago.

Because its light is 727 million ly from home, you are seeing IC 2593 as it looked roughly 727 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.
