Turns out we should be worried about asteroids, also.
According to "USA Today", NASA was ordered by Congress four years ago to watch 90% (what, the other 10% don't count?) of the asteroids in space which may pose a threat to earth. One small yet significant problem: Congress did not come through with the money for enough telescopes to do this.
Guess y'all best get out your telescopes and start watchin'.
