The team recreated a turbulent magnetic reconnection, suggested to be a trigger of solar flares.
On January 10, NASA's Solar Dynamics Observatory recorded a massive X-class solar flare. The blast hurled debris into space, and radiation from the flare triggeredacross the South Pacific. The solar outburst was the third X-class — the most powerful — flare in less than a week.
of its newly launched Starlink communications satellites due to a geomagnetic storm triggered by a solar flare.To better understand solar flares and protect satellites, and power grids on Earth, for the first time, researchers in China have used powerful lasers to recreate magnetic explosions on the surface of the Sun,The team stimulated a turbulent magnetic reconnection in which the Sun's anti-parallel magnetic fields dramatically collide, break, and realign.
"In that experiment, we properly scaled key parameters to make sure it is compatible with an actual solar flare on the sun," Zhong said.In 2010, they recreated magnetic reconnection by employing two high-power lasers to trigger an aluminum foil and generate plasma bubbles. As these bubbles expanded, the magnetic fields collided, and magnetic reconnection was observed.of the Sun was much more complex, while the experiment only mimicked a simple version of magnetic reconnection.
