Science Buddies: Correlation of Coronal Mass Ejections With Solar Sunspot Cycle
Scientists have known for hundreds of years that sunspot activity waxes and wanes over a cycle that lasts approximately 11 years. In the 1970's, scientists discovered that the sun periodically blasts electrified gases into space, in huge...
