The origin of our moon is an enduring mystery for planetary scientists. One theory supposes that another planet slammed into Earth, and in the aftermath of that collision, the moon emerged. Rachel Feltman, who runs the “Speaking of Science” blog at the Washington Post, talks about three studies out this week that inch us closer to an answer. Plus, she reviews a few new findings about life’s prevalence in the cosmos.
And last weekend, the first protons made the rounds in a newly souped-up Large Hadron Collider. After two years of tune-ups, the world’s biggest physics machine is turning back on—at nearly twice the proton-smashing power. The BBC’s Jonathan Webb joins us for a preview of what physicists are hoping to turn up, and how long the search for new particles might take.
