NGC 7534

NGC 7534 is an irregular galaxy in the constellation Pisces about 163 million ly from Earth. It spans roughly 47,000 ly, about 47% of our Milky Way's width. The light reaching us tonight left it about 163 million years ago.

Because its light is 163 million ly from home, you are seeing NGC 7534 as it looked roughly 163 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.
