NGC 5532

NGC 5532 is a lenticular galaxy in the constellation Boötes about 345 million ly from Earth. It spans roughly 230,000 ly, about 2.3 times the width of our Milky Way. It is receding from us at about 7,116 km/s.

Because its light is 345 million ly from home, you are seeing NGC 5532 as it looked roughly 345 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.
