MADISON - The sun's solar wind affects nearly everything in the solar system. It can disrupt the function of Earth's satellites and creates the lights of the auroras. A new study by University of ...

Ball lightning – the mysterious slow-moving spheres of light occasionally seen during thunderstorms – has been created in the lab. Researchers at the Max Planck Institute for Plasma Physics and the ...

Physicists at the University of Wisconsin-Madison built a swirling orb of plasma they’re calling a “miniature Sun” — so they can study how stars work up close. The mini-sun, complete with its own ...

Ball lightning has mystified scientists and witnesses for centuries, appearing as glowing orbs during thunderstorms that seem ...

Cary Forest, a professor of physics and lead researcher for the new Wisconsin Plasma Physics Laboratory (WiPPL), stands next to the Big Red Plasma Ball in Sterling Hall. The Big Red Plasma Ball is one ...

Scientists have built a miniature model of the Sun that could protect us from the real version. The "big red plasma ball", created in a lab, could allow researchers to finally understand the ...

Plasma exists in a mixed form of electrons, positive ions and neutral atoms or molecules and plays an important role in many processes; from astrophysical solar flares to nuclear fusion devices for ...
