NGC 5736

NGC 5736 is a lenticular galaxy in the constellation Boötes about 393 million ly from Earth. It spans roughly 110,000 ly, about the width of our Milky Way. The light reaching us tonight left it about 393 million years ago.

Because its light is 393 million ly from home, you are seeing NGC 5736 as it looked roughly 393 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.
