Shedding light on the science of auroral breakups

Auroras, also known as Northern or Southern lights depending on where they occur, are natural displays of light in the Earth's sky. Typically, these lights are dimly present at night. However, sometimes, these otherwise faint ...

Major space mystery solved using data from student satellite

A 60-year-old mystery regarding the source of some energetic and potentially damaging particles in Earth's radiation belts is now solved using data from a shoebox-sized satellite built and operated by University of Colorado ...

Relativistic electrons uncovered with NASA's Van Allen Probes

Earth's radiation belts, two doughnut-shaped regions of charged particles encircling our planet, were discovered more than 50 years ago, but their behavior is still not completely understood. Now, new observations from NASA's ...

Van Allen probes revolutionize view of radiation belts

About 600 miles from Earth's surface is the first of two donut-shaped electron swarms, known as the Van Allen Belts, or the radiation belts. Understanding the shape and size of the belts, which can shrink and swell in response ...

Space balloons and charged particles above the Arctic Circle

I research space weather. That's how physicists describe how storms on the sun end up affecting us here on Earth. Most days I sit at a computer coding, attending telephone conference meetings with collaborators across the ...
