NGC 5341

NGC 5341 is a barred spiral galaxy in the constellation Canes Venatici about 170 million ly from Earth. It spans roughly 53,000 ly, about 53% of our Milky Way's width. The light reaching us tonight left it about 170 million years ago.

Because its light is 170 million ly from home, you are seeing NGC 5341 as it looked roughly 170 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.
