Awesome Detectors


The Ghost Particle homepage

Launch slide show Awesome Detectors

Scientists estimate that many hundreds of billions of neutrinos will have harmlessly sped through your body by the time you finish reading this sentence. But despite their abundance, there's only a 10 percent chance over the course of your entire lifetime that even one of these invisible particles will ever (again, harmlessly) interact with any other particle in your body. Because of the rarity of collisions between neutrinos and matter—events that are necessary to perceive or study these spectral particles—neutrinos play an expert game of hard-to-get with physicists, who have designed giant, extremely sensitive detectors to seek them out. In this slide show, take a tour of some of the most intriguing neutrino experiments around the globe, and find out what tantalizing results keep the experts on the trail of the ghost particle. To launch the slide show, click on the image at left.—Lexi Krock
