A balloon — which looks a translucent white pumpkin, but large enough to hug a football field — will soon take flight, carrying a solar scope called BITSE. BITSE is a coronagraph, a special kind of telescope that blocks the bright face of the Sun to reveal its dimmer atmosphere, called the corona. BITSE stands for Balloon-borne Investigation of Temperature and Speed of Electrons in the corona. Its goal? Explaining how the Sun spits out the solar wind, the stream of charged particles that blows constantly from the Sun. Scientists generally know it forms in the corona, but exactly how it does so is a mystery. The solar wind is important b...
