Should the government prioritize funding for basic scientific research, even without immediate practical applications?
Researchers have successfully produced laboratory nanoflares to simulate complex solar processes. By utilizing high-power lasers on plastic targets, the team demonstrated how magnetic field rearrangement increases plasma temperatures.
Why it matters
The study aims to solve a long-standing solar mystery regarding why the corona is significantly hotter than the sun's surface. These laboratory insights help scientists understand the energy emission mechanisms driving solar heating.
The experiment involved firing four high-power lasers at a target to create a 2-millimetre plasma patch. Temperatures reached 799,726°C when a wavy target surface triggered nanoflare energy emission.
