NGC 1550

NGC 1550 is an elliptical galaxy in the constellation Taurus about 172 million ly from Earth. It spans roughly 87,000 ly, about the width of our Milky Way. It is receding from us at about 3,689 km/s.

Because its light is 172 million ly from home, you are seeing NGC 1550 as it looked roughly 172 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.
