没想到啊，竟然是动图！！！

Tsunamis this large don't happen on Earth. During 2006, a large solar flare from an Earth-sized sunspot produced a tsunami-type shock wave that was spectacular even for the Sun. Pictured here, the tsunami wave was captured moving out from active region AR 10930 by the Optical Solar Patrol Network (OSPAN) telescope in New Mexico, USA. The resulting shock wave, known technically as a Moreton wave, compressed and heated up gasses including hydrogen in the photosphere of the Sun, causing a momentarily brighter glow. The featured image was taken in a very specific red color emitted exclusively by hydrogen gas. The rampaging tsunami took out some active filaments on the Sun, although many re-established themselves later. The solar tsunami spread at nearly one million kilometers per hour, and circled the entire Sun in a matter of minutes.

地球上不会发生这么大的海啸。2006年，一个地球大小的太阳黑子发出的巨大太阳耀斑产生了海啸式的冲击波，甚至对太阳来说也是壮观的。图中，位于美国新墨西哥州的光学太阳巡更网（OSPAN）望远镜捕捉到海啸波从活跃区域AR 10930向外移动。由此产生的冲击波，在技术上称为莫尔顿波，压缩并加热了包括太阳光球层中的氢在内的气体，产生了瞬间更亮的辉光。这张特写图片是用一种非常特殊的红色拍摄的，这种红色完全是由氢气发出的。肆虐的海啸摧毁了太阳上一些活跃的细丝，尽管许多细丝后来重新形成。太阳海啸以每小时近100万公里的速度传播，在几分钟内环绕整个太阳。
