NGC 7249

NGC 7249

NGC 7249 is a lenticular galaxy in the constellation Grus about 564 million ly from Earth. It spans roughly 160,000 ly, about 1.6 times the width of our Milky Way. It is receding from us at about 12,005 km/s.

Because its light is 564 million ly from home, you are seeing NGC 7249 as it looked roughly 564 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.
