Neutrinos on Ice: Waiting to Fly

ANITA rolling out to the launchpad. (Katie Mulrey)

It’s another beautiful day in Antarctica, and the time has come to launch ANITA! Finding the right date is tricky. Many factors have to fall into place. In order to detect neutrinos and cosmic rays, we want to fly over the Eastern ice sheet in Antarctica. We detect these particles via their radio emission. The [...]

Paris: City of lights and cosmic rays

Paris has long had the nickname the "City of Lights," due to its role as a center of education during the Age of Enlightenment and, in the 1800s, due to its early implementation of electric lighting. It very nearly had its name associated with another form of radiation in 1910, however, thanks to a truly [...]

Fermi Satellite Tracks Cosmic-Ray Origins Back to Supernova Remnants

Supernova shock wave

The cosmos is full of surprises—not a week goes by without some group of astronomers announcing a perplexing new discovery that upends theory or expectation. But equally important is the difficult and time-consuming research required to firmly pin down what astronomers think they already know. Take, for instance, a new study on the origins of [...]
