NGC 3406 NED01

NGC 3406 NED01 is an elliptical galaxy in the constellation Ursa Major about 349 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 349 million years ago.

Because its light is 349 million ly from home, you are seeing NGC 3406 NED01 as it looked roughly 349 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.
