NGC 5887

NGC 5887 is a lenticular galaxy in the constellation Serpens about 409 million ly from Earth. It spans roughly 160,000 ly, about 1.6 times the width of our Milky Way. The light reaching us tonight left it about 409 million years ago.

Because its light is 409 million ly from home, you are seeing NGC 5887 as it looked roughly 409 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.
