NGC 2819

NGC 2819 is an elliptical galaxy in the constellation Cancer about 419 million ly from Earth. It spans roughly 180,000 ly, about 1.8 times the width of our Milky Way. The light reaching us tonight left it about 419 million years ago.

Because its light is 419 million ly from home, you are seeing NGC 2819 as it looked roughly 419 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.
