Comet Hyakutake blazes in X-rays
Article Abstract:
Astronomers who pointed the German X-ray Roentgen Satellite at Comet Hyakutake were surprised by a brilliant x-ray emission, since no x-rays had ever before been detected from a comet. One theory is that solar x-rays interacting with water molecules in the comet produced the emission.
