NGC 3891

NGC 3891 is a barred spiral galaxy in the constellation Ursa Major about 293 million ly from Earth. It spans roughly 150,000 ly, about the width of our Milky Way. It is receding from us at about 6,196 km/s.

Because its light is 293 million ly from home, you are seeing NGC 3891 as it looked roughly 293 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.
