Scientists at Aberystwyth University presented a movie of a solar twister yesterday at the National Astronomy Meeting in Manchester, England. The images were collected last September by a telescope on NASA's Solar Dynamic Observatory (SDO) satellite, which tracks variations in the sun to help predict space weather.
