NGC 3150

NGC 3150 is a barred spiral galaxy in the constellation Leo Minor about 341 million ly from Earth. It spans roughly 100,000 ly, about the width of our Milky Way. The light reaching us tonight left it about 341 million years ago.

Because its light is 341 million ly from home, you are seeing NGC 3150 as it looked roughly 341 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.
