NGC 7618

NGC 7618 is an elliptical galaxy in the constellation Andromeda about 243 million ly from Earth. It spans roughly 87,000 ly, about the width of our Milky Way. It is receding from us at about 5,234 km/s.

Because its light is 243 million ly from home, you are seeing NGC 7618 as it looked roughly 243 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.
