IC 3240

IC 3240 is a barred spiral galaxy in the constellation Virgo about 993 million ly from Earth. It spans roughly 130,000 ly, about the width of our Milky Way. The light reaching us tonight left it about 993 million years ago.

Because its light is 993 million ly from home, you are seeing IC 3240 as it looked roughly 993 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.
