Watch For Old Light

The lighter side of the news: 13 billion-year-old light finally reaches Earth.

Distant-starx-large Light from a star that exploded over 13 billion years ago is just now reaching Earth. The star is about 13.1 billion light years away and sets the record for the farthest object in space to be observed, according to two separate studies in Nature magazine.

So if you see some light that looks really, really, old, you'll know where it came from.
