What to know about Scientific Discovery/Space Weather

Scientists are using a citizen science project called HARP to study space weather by translating Earth's magnetic field measurements into sound. Volunteers discovered an unexpected pattern in plasma waves from NASA's THEMIS mission, noting that some waves exhibited lower pitches near Earth and higher pitches farther away, which aids understanding of geomagnetic storms.

What happened

Volunteers discover rare space weather events using their ears Gaby Clark scientific editor Robert Egan associate editor Our planet rests inside a magnetic cocoon filled with plasma—but it's not always peaceful and quiet.

Why it matters

Activity from the sun can send waves through this space, and some of those disturbances can even reach Earth, affecting our power grid.

Common ground

Scientists are working to understand exactly how these waves behave, and the team behind NASA's Heliophysics Audified: Resonances in Plasmas (HARP) citizen science project approaches this in a unique way: they compare the Earth's magnetic field to a giant…
