NGC 3846A

NGC 3846A is an irregular galaxy in the constellation Ursa Major about 67 million ly from Earth. It spans roughly 38,000 ly, about 38% of our Milky Way's width. The light reaching us tonight left it about 67 million years ago.

Because its light is 67 million ly from home, you are seeing NGC 3846A as it looked roughly 67 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.
