NGC 3664A

NGC 3664A is a spiral galaxy in the constellation Leo about 62 million ly from Earth. It spans roughly 11,000 ly, about 11% of our Milky Way's width. The light reaching us tonight left it about 62 million years ago.

Because its light is 62 million ly from home, you are seeing NGC 3664A as it looked roughly 62 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.
