(Newser) – Two satellites launched in 2006 reached their final destinations this week, giving us, for the first time ever, the ability to see the entire sun. The Solar Terrestrial Relations Observatory (STEREO) spacecraft are on opposite sides of the sun, and will continue to provide a complete view of the sun’s surface for eight years, NASA reports. In addition to just being incredibly neat, the new view could reveal fresh information: For instance, scientists will be able to study a long-running suspicion—that solar activity can "go global," with an eruption on one side of the sun triggering one on the opposite side.
