NGC 3025

NGC 3025 is a lenticular galaxy in the constellation Hydra about 394 million ly from Earth. It spans roughly 180,000 ly, about 1.8 times the width of our Milky Way. The light reaching us tonight left it about 394 million years ago.

Because its light is 394 million ly from home, you are seeing NGC 3025 as it looked roughly 394 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.
