IC 2575

IC 2575 is a barred spiral galaxy in the constellation Antlia about 806 million ly from Earth. It spans roughly 150,000 ly, about the width of our Milky Way. The light reaching us tonight left it about 806 million years ago.

Because its light is 806 million ly from home, you are seeing IC 2575 as it looked roughly 806 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.
