NGC 5486

NGC 5486 is a spiral galaxy in the constellation Ursa Major about 64 million ly from Earth. It spans roughly 25,000 ly, about 25% of our Milky Way's width. It is receding from us at about 1,317 km/s.

Because its light is 64 million ly from home, you are seeing NGC 5486 as it looked roughly 64 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.
