Sorry, Raoul.
The only URL I can give you on this story is www.space.com.
I'm too lazy, or tired, to give you a better one. You'll have to search for it yourself

It seems, HM QE2, was recently touring
a space science/astronomy facility in the UK and she asked someone there some remarkably educated questions about
the danger posed by NEO asteroids, and how to deflect them.
Seems Her Majesty is more space/astronomy savvy than most
give her credit.

By the way, she's not the first celebrity
to show interest in space science. The former late night TV comedian, Johnny Carson is an amateur astronomer. Go figure, Phil.
