NGC 3040 NED02

NGC 3040 NED02 is a lenticular galaxy in the constellation Leo about 359 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 359 million years ago.

Because its light is 359 million ly from home, you are seeing NGC 3040 NED02 as it looked roughly 359 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.
