- Cosmic ray muons expose thunderstorm electric fields — Phys.org
An instrument built to study cosmic rays has turned out to be a powerful tool for investigating thunderstorms. Earlier observations with the GRAPES-3 muon telescope revealed that thunderclouds can develop electrical potential differences far greater than those ever measured directly. A new study by the same team, published in the Journal of Cosmology and Astroparticle Physics, has now explained an asymmetry in detections. The asymmetry arises from the way the geomagnetic field affects the cosmic rays traveling through Earth's magnetosphere. GRAPES-3, located in Ooty, India, includes a 560-square-meter muon telescope that records around 4 billion muons every day. Positive and negative muons do not arrive at the detector in equal numbers because primary cosmic rays are mostly positively charged.

Choruses of African elephant rumbles appear to become more similar in certain situations, including reuniting or coordinating what to do next. New research published in Scientific Reports provides evidence that elephant rumble choruses function as group signals. The study examined how choruses change during specific social contexts. Researchers recorded and analyzed rumble patterns across multiple groups. The findings show that similarity in choruses increases when groups need to align actions.

Planetterrian Spotlight
The GRAPES-3 muon telescope records four billion muons daily yet was never built to study weather. Its sensitivity to thunderstorm electric fields stems from how Earth's magnetic field steers charged particles differently depending on arrival direction. Positive muons outnumber negative ones, creating a natural charge-ratio probe that amplifies small field effects. The new analysis shows the east-west detection asymmetry is an artifact of geomagnetic filtering rather than any real difference in storm frequency. This turns an existing cosmic-ray detector into a distributed sensor network for atmospheric electricity without new hardware. Future work could combine multiple muon telescopes to map field strength across regions.
Science Deep Dive: How Thunderstorms Generate Extreme Electric Fields
Most people assume thunderstorms are mainly about rain, wind and the occasional lightning bolt we see from the ground. In reality, right now inside any active storm cell, charge separation between ice particles and water droplets is building electric fields that can reach hundreds of millions of volts. The GRAPES-3 telescope in India detects four billion muons every day; those muons bend measurably when they pass through these fields, giving physicists a remote readout of voltage differences far larger than anything measured by weather balloons. One memorable number is that the potential differences inside thunderclouds exceed one hundred million volts, roughly ten times higher than the strongest fields recorded by aircraft instruments. This changes how we think about lightning initiation and also about radiation exposure for high-altitude flights. Next time you hear thunder, remember the invisible voltage structure above you is being mapped by particles that arrived from outer space.
That covers today's research findings from primary sources. |
