NGC 5256 NED02

NGC 5256 NED02 is a spiral galaxy in the constellation Ursa Major about 383 million ly from Earth. It spans roughly 160,000 ly, about 1.6 times the width of our Milky Way. The light reaching us tonight left it about 383 million years ago.

Because its light is 383 million ly from home, you are seeing NGC 5256 NED02 as it looked roughly 383 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.
