NGC 2490

NGC 2490 is an elliptical galaxy in the constellation Gemini about 316 million ly from Earth. It spans roughly 58,000 ly, about 58% of our Milky Way's width. The light reaching us tonight left it about 316 million years ago.

Because its light is 316 million ly from home, you are seeing NGC 2490 as it looked roughly 316 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.
