NGC 5439

NGC 5439 is a spiral galaxy in the constellation Canes Venatici about 88 million ly from Earth. It spans roughly 33,000 ly, about 33% of our Milky Way's width. The light reaching us tonight left it about 88 million years ago.

Because its light is 88 million ly from home, you are seeing NGC 5439 as it looked roughly 88 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.
