The video: Remember February's solar flares that threatened to knock out our communication systems here on earth? Well, NASA caught one on tape last week (see the video below), recording it from NASA's Solar Dynamics Observatory (SDO) spacecraft using extreme ultraviolent light. The dramatic flare can be seen spurting out a fiery prominence thousands of miles long. Although serious solar flares can pose a threat to earth, this one was not pointed in our direction. 
The reaction: This "incredible" footage almost defies comprehension, says Phil Plait at Discover, especially when you consider that "the entire Earth would be a smallish dot on this scale." The super-HD images sent back by the SDO mean "we can zoom in on the action and still see exquisite details," says Jesus Diaz at Gizmodo. It's a "jaw-dropping solar show." Watch it for yourself here:
