NGC 970 NED02

NGC 970 NED02 is a galaxy in the constellation Triangulum about 457 million ly from Earth. It spans roughly 96,000 ly, about the width of our Milky Way. The light reaching us tonight left it about 457 million years ago.

Because its light is 457 million ly from home, you are seeing NGC 970 NED02 as it looked roughly 457 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.
