NGC 5515

NGC 5515 is a spiral galaxy in the constellation Boötes about 361 million ly from Earth. It spans roughly 130,000 ly, about the width of our Milky Way. It is receding from us at about 7,603 km/s.

Because its light is 361 million ly from home, you are seeing NGC 5515 as it looked roughly 361 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.
