NGC 4188

NGC 4188 is a barred spiral galaxy in the constellation Corvus about 199 million ly from Earth. It spans roughly 39,000 ly, about 39% of our Milky Way's width. The light reaching us tonight left it about 199 million years ago.

Because its light is 199 million ly from home, you are seeing NGC 4188 as it looked roughly 199 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.
