NGC 4287

NGC 4287 is a barred spiral galaxy in the constellation Virgo about 100 million ly from Earth. It spans roughly 35,000 ly, about 35% of our Milky Way's width. The light reaching us tonight left it about 100 million years ago.

Because its light is 100 million ly from home, you are seeing NGC 4287 as it looked roughly 100 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.
