NGC 4344

NGC 4344 is a lenticular galaxy in the constellation Coma Berenices about 54 million ly from Earth. It spans roughly 21,000 ly, about 21% of our Milky Way's width. The light reaching us tonight left it about 54 million years ago.

Because its light is 54 million ly from home, you are seeing NGC 4344 as it looked roughly 54 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.
