Je viens de lire qu'il y aurait des Tsunami sur le soleil http://science.slashdot.org/story/09/11/25/151219/STEREO-Satellites-Spot-Solar-Flare-Tsunami?from=rss

Slashdot saided :

westtxfun writes "The STEREO satellites recently confirmed the existence of solar mega-tsunamis when they captured height data after a sunspot recently erupted. The scale of this tsunami literally dwarfs the Earth's diameter — it was 62,000 miles high and raced across the surface at 560,000 mph! STEREO A and B orbit 90 degrees apart and luckily, one was overhead while the other saw the eruption on the limb. This gave NASA scientists enough data to confirm the tsunami wasn't a shadow, solving a modern solar mystery. The images are simply stunning, to boot."
