The probe launched almost 50 years ago and is the farthest human-made object from Earth. Shutting down one of its scientific devices will help it conserve energy and continue traveling toward the edge ...

Astronomers analyzed the vapors coming off the comet when it neared the sun and found it had a lot of "heavy" water. That hints it grew up in a frigid planetary system, possibly before its home star f ...
