IC 727

IC 727

IC 727 is a barred spiral galaxy in the constellation Leo about 284 million ly from Earth. It spans roughly 140,000 ly, about the width of our Milky Way. The light reaching us tonight left it about 284 million years ago.

Because its light is 284 million ly from home, you are seeing IC 727 as it looked roughly 284 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.
