NGC 1690

NGC 1690 is an elliptical galaxy in the constellation Orion about 408 million ly from Earth. It spans roughly 130,000 ly, about the width of our Milky Way. The light reaching us tonight left it about 408 million years ago.

Because its light is 408 million ly from home, you are seeing NGC 1690 as it looked roughly 408 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.
