In 2008, the sun entered a deep lull in magnetic activity. Spacecraft measurements show that this caused a belt of sluggish particles, known as the slow solar wind, to thicken. The belt is ruched like a ballerina's tutu, and Earth passes in and out of its ruches during the year. As solar activity dwindles, the belt thickens, and we spend more time passing through it. The speed of the slow solar wind affects the temperature of Earth's upper atmosphere, and impacts climate. ..."
