Today, researchers working with the Large Underground Xenon (LUX) detector at the Sanford Underground Research Facility in Lead, South Dakota, announced that they see no signs of the lightweight dark matter particles hinted at by other experiments.

"Earth's first portrait surfaced more than 20 years ago, courtesy of Voyager 1. In that historical shot from 1990, Earth figures as a “pale blue dot,” barely perceptible against a ray of scattering light (see below). In 1994, Carl Sagan, an experimenter for the Voyager 1 and 2 spacecraft, chatted with SciFri about first seeing that dot. “I thought, that’s us,” he said. “That’s our world. That’s all of us—everybody you know, everybody you love, everybody you ever heard of lived out their lives there, on a mote of dust in a sunbeam.” Listen to the conversation in the podcast below."
