Making Ultra-fast Electron Measurements in Multiple Directions to Reveal the Secrets of the Aurora
The energetic electrons that drive the aurora borealis (the northern lights) have a rich and very dynamic structure that we currently do not fully understand. Much of what we know about these electrons comes from instruments that have fundamental limitations in their ability to sample multiple energies with high time resolution. To overcome these limitations, NASA is using an innovative approach to develop instrumentation that will enhance our measurement capabilities by more than an order of magnitude—revealing a wealth of new information about the amazing physics happening within the aurora.

The April 8, 2024, total solar eclipse will produce stunning views across North America. While anyone along the eclipse path with a clear sky will see the spectacular event, the best view might be 50,000 feet in the air, aboard NASA’s WB-57 jet planes. That’s where a trio of NASA-funded teams are sending their scientific […]

Our Sun, like many stars, is adorned with a crown. It’s called a corona (Latin for “crown” or “wreath”) and consists of long, thread-like strands of plasma billowing out from the Sun’s surface. The powerful magnetic field of the Sun defines these strands, causing them to ripple and evolve their structures constantly. The strands are […]
