Asteroid Day was this week, and in honor of the completely unknown holiday, campaigners issued a call to action – we must spend more time and money trying to blow up speeding space rocks 🚀

Lord Rees, the astronomer royal, and Brian May, from the rock group Queen, added their names to the 100X declaration (along with Peter Gabriel, Richard Dawkins, Brian Cox and Eileen Collins). They also spoke with the Guardian about this pressing issue.
