NGC 3134

NGC 3134 is a barred spiral galaxy in the constellation Leo about 255 million ly from Earth. It spans roughly 110,000 ly, about the width of our Milky Way. The light reaching us tonight left it about 255 million years ago.

Because its light is 255 million ly from home, you are seeing NGC 3134 as it looked roughly 255 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.
