IC 577

IC 577 is a spiral galaxy in the constellation Leo about 419 million ly from Earth. It spans roughly 76,000 ly, about 76% of our Milky Way's width. It is receding from us at about 9,009 km/s.

Because its light is 419 million ly from home, you are seeing IC 577 as it looked roughly 419 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.
