木星极光的规模和亮度远超地球

2025-05-13 15:06 by 诺比与平行宇宙的钥匙

NASA 韦伯太空望远镜近期捕捉到木星极光前所未见的变化细节,显示木星极光会在几秒内剧烈变化,其上层大气的能量动态远比原先认为的更加复杂。在北极高空中,极光不仅「闪烁」、「跳动」,甚至能在短短数秒内迅速改变。这些观测揭示,木星强大的磁场会加速带电粒子,使其以极高能量撞击大气,产生剧烈的红外发光现象,其亮度与规模远超地球极光。相关研究报告发表在《Nature Communications》期刊上。

The seemingly negative pandemic effects and resource/product shortages are encouraging and allowing organizations to innovate and change.The news of cash-rich organizations getting ready for the post-Covid growth economy is a sign of more than capital spending plans. Cash provides a cushion for risk-taking and a tool for growth.
