NGC 5889

NGC 5889 is a barred spiral galaxy in the constellation Boötes about 601 million ly from Earth. It spans roughly 120,000 ly, about the width of our Milky Way. The light reaching us tonight left it about 601 million years ago.

Because its light is 601 million ly from home, you are seeing NGC 5889 as it looked roughly 601 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.
