NGC 4842A

NGC 4842A is an elliptical galaxy in the constellation Coma Berenices about 341 million ly from Earth. It spans roughly 57,000 ly, about 57% of our Milky Way's width. It is receding from us at about 7,297 km/s.

Because its light is 341 million ly from home, you are seeing NGC 4842A as it looked roughly 341 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.
