NGC 6998

NGC 6998 is an elliptical galaxy in the constellation Microscopium about 561 million ly from Earth. It spans roughly 150,000 ly, about 1.5 times the width of our Milky Way. It is receding from us at about 11,672 km/s.

Because its light is 561 million ly from home, you are seeing NGC 6998 as it looked roughly 561 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.
