Now You Can Listen to the Moon Landing

On July 20, 1969, just before 11 p.m. Eastern time, Neil Armstrong planted the first human footprints on another world. It was a defining moment in a journey that had transfixed the planet.

Surprising Discovery Gives "Plasma Lenses" a Clearer Future

It might surprise you that scientists at CERN—the home of the world’s largest particle accelerator—don’t always think bigger is better. At 17-miles in diameter, CERN’s Large Hadron Collider (LHC) is the biggest and most powerful particle accelerator in the world. It’s the hub of high energy physics research, drawing scientists from around the globe and managing to make the Higgs boson a household name. But as CERN researchers look to the future, some of them are thinking small. Well, small in size, not small in impact.

Next-Gen Satellites May Use Lasers to Part the Clouds

Scientists of the future huddle around a computer, waiting for an HD live stream of the incoming asteroid. As the probe that will provide the crucial communication slowly moves into view of the asteroid, they know that every second counts. In a surprising move, they tune their receivers not to radio frequencies, like we do today, but to a much higher frequency—somewhere in the near-infrared. But they think nothing of it—infrared and visible light allows for a much better transmission of data, and all of the leading satellite producers have switched over by now. But at the last minute, a cloud rolls in above the station, scattering the message from the relay satellite in all directions and cutting off the receiver.

That’s where the work of Dr. Jean-Pierre Wolf comes in.
