interacting with Earth’s magnetic field – they’re not sure what causes their unique movements. Specifically, researchers at NASA want to understand why some auroras flicker, others pulsate ...

In fact, the discovery actually supports a key part of the theory about how chorus waves work. Using data from the ...

Largely under the command of NASA ... auroras and connections between the sun and the Earth. "One of the most important aspects of auroras is that the polar regions are where the magnetic field ...

To help to that end, the rockets NASA wants to launch into the auroras are equipped with instruments to study the interaction between electrons and Earth's magnetic field. Each rocket will target ...

and occasionally producing spectacular aurora. But the Earth's magnetic fields are not as fixed as you might think. "We know that over the past 200 years, the magnetic field has weakened about 9 ...

Today, those NASA missions would be a centennial extension to continue building, exploring the science behind the northern lights and more generally to get at Earth's magnetic field and the ...

NASA astronaut Don ... What is the aurora phenomenon? Interactions between solar wind (streams of charged particles from the Sun) and Earth's magnetic field cause auroras. The collisions of ...

Farther out in the tail, the lines of Earth's magnetic field have been stretched and warped into something much messier. Physicists didn't think chorus waves could form amid the stretched-out mess ...
