Another YouTube Channel I am subscribed to is NASA Goddard Space Flight Center (NASAexplorer). They upload some pretty fantastic videos of space stuff, as well as Earth stuff seen from space. These are two recent clips I thought were very intriguing. The first video is explaining the categories of solar flares on the sun. The second video describes how researchers witnessed, for the first time, a tsunami (the same one that recently hit Japan) triggering iceberg separation.
