NGC 1273

NGC 1273 is a lenticular galaxy in the constellation Perseus about 249 million ly from Earth. It spans roughly 65,000 ly, about 65% of our Milky Way's width. It is receding from us at about 5,351 km/s.

Because its light is 249 million ly from home, you are seeing NGC 1273 as it looked roughly 249 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.
