NGC 1515

NGC 1515 is a spiral galaxy in the constellation Dorado about 55 million ly from Earth. It spans roughly 88,000 ly, about the width of our Milky Way. It is receding from us at about 1,216 km/s.

Because its light is 55 million ly from home, you are seeing NGC 1515 as it looked roughly 55 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.
