NGC 4373

NGC 4373 is an elliptical galaxy in the constellation Centaurus about 159 million ly from Earth. It spans roughly 180,000 ly, about 1.8 times the width of our Milky Way. It is receding from us at about 3,396 km/s.

Because its light is 159 million ly from home, you are seeing NGC 4373 as it looked roughly 159 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.
