Lee Rannals for redOrbit.com - Your Universe Online The intrepid comet Lovejoy flew right into the Sun's violent atmosphere and lived to tell scientists the story and help them understand more about our local star. In December 2011, comet Lovejoy plowed into the Sun's atmosphere, withstanding temperatures that would have obliterated any man-made object. Telescope images taken of the comet's miraculous feat showed how the comet's tail was pulled about by an intense magnetic field. This...

Filaments of magnetism snapped and exploded, shock waves raced across the stellar surface, billion-ton clouds of hot gas billowed into space. Astronomers knew they had witnessed something big. It was so big, it may have shattered old ideas about solar activity. "The August 1st event really opened our eyes," says Karel Schrijver of Lockheed Martin's Solar and Astrophysics Lab in Palo Alto, CA. "We see that solar storms can be global...

New satellite imagery of the sun is providing scientists with clues to understanding the long-standing mystery of what is heating up the solar corona The 2006 launch of the multinational Hinode satellite changed the picture of the sun for astrophysicists. For two astrophysicists in particular, the resulting imagery offered a voyage of discovery and the thrill of unraveling a long-held solar mystery. The Earth's atmosphere can obscure the view of unaided ground-based telescopes, but,...
