NGC 1145

NGC 1145 is a spiral galaxy in the constellation Eridanus about 97 million ly from Earth. It spans roughly 95,000 ly, about the width of our Milky Way. The light reaching us tonight left it about 97 million years ago.

Because its light is 97 million ly from home, you are seeing NGC 1145 as it looked roughly 97 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.
