As expected, the Sun's ultraviolet radiation split the water molecules, liberating a cloud of hydrogen atoms, which glowed in the ultraviolet light. With the distance between the comet and the Sun quickly decreasing, the amount of solar radiation hitting the comet increased, as did the release of vapour from the nucleus and the consequent production of hydrogen. In ultraviolet light, the comet projected a distinct shadow on the hydrogen haze of the Solar System. As in the case of the comet's shadow, it keeps making discoveries and amazing observations. Now, a trio of scientists says it's because the corona is heated by incessant mini-explosions, called microflares.
Physicists discover a new tool for predicting solar eruptions.
