NGC 1357

NGC 1357

NGC 1357 is a spiral galaxy in the constellation Eridanus about 93 million ly from Earth. It spans roughly 91,000 ly, about the width of our Milky Way. It is receding from us at about 1,999 km/s.

Because its light is 93 million ly from home, you are seeing NGC 1357 as it looked roughly 93 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.
