When these gamma rays smash into the upper atmosphere, they blast apart atoms in the air, producing a shower of particles that moves at nearly the speed of light toward the ground. When this shower reaches HAWC&#8217;s tanks, it produces coordinated flashes of blue light in the water, allowing researchers to reconstruct the energy and cosmic origin of the gamma ray that kicked off the cascade. <\/p>\n","protected":false},"excerpt":{"rendered":"<p>Astronomers have used a high-altitude observatory in Mexico to better understand where gamma rays come from.
