这么大的海啸在地球上不会发生。2006年,一颗地球大小的太阳黑子产生了一场巨大的太阳耀斑,产生了海啸式的冲击波,即使对太阳来说也很壮观。图为位于美国新墨西哥州的光学太阳能巡逻网(osan)望远镜捕捉到的海啸波从活跃区域ar10930向外移动。由此产生的冲击波,在技术上被称为摩尔顿波,压缩并加热了太阳光球层中的气体,包括氢,导致短暂的更亮的光芒。这张特色图片是用一种特殊的红色拍摄的,这种红色是由氢气发出的。狂暴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建立起来。太阳海啸以每小时近一百万公里的速度传播,并在几分钟内围绕整个太阳旋转。

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.
