NGC 2690

NGC 2690 is a spiral galaxy in the constellation Hydra about 75 million ly from Earth. It spans roughly 37,000 ly, about 37% of our Milky Way's width. The light reaching us tonight left it about 75 million years ago.

Because its light is 75 million ly from home, you are seeing NGC 2690 as it looked roughly 75 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.
