NGC 4892

NGC 4892 is a lenticular galaxy in the constellation Coma Berenices about 276 million ly from Earth. It spans roughly 110,000 ly, about the width of our Milky Way. It is receding from us at about 5,895 km/s.

Because its light is 276 million ly from home, you are seeing NGC 4892 as it looked roughly 276 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.
