An interplanetary shock wave from the Sun struck Earth's magnetosphere just before the peak of the Perseid meteor shower on August 12, 2000, triggering a powerful geomagnetic storm. Stargazers across Canada and the United States were treated to the rare spectacle of a meteor shower seen against the backdrop of colorful Northern Lights.

What do the racing winds on Jupiterand the snail's pace circulation of molten rock inside the Earth have in common? They're all fluids whose movements were simulated in a "planet in a test tube" flown aboard the Space Shuttlein 1985 and 1995. Results from the Geophysical Fluid Flow Cell experiments were published last month in a NASA Technical Memorandum.

NASA's NEAR Shoemaker spacecraft has spotted square-shaped craters on asteroid Eros, a telltale sign of mysterious goings-on in the asteroid belt long ago. Square craters add to accumulating evidence that the Eros is riddled with cracks and ridges that extend the entire 33 km length of the peanut-shaped space rock.
