...spectrum has two large peaks that may or may not mark an ample presence of an as yet unidentified element, and many small dips that probably represent segments of the spectrum where light has been absorbed by other elements--perhaps those in the object's outer atmosphere or in gas clouds between the object and Earth. Bewildered, the Caltech team looked for other answers. Maybe the object was a supernova, an exploding star, which often projects what Djorgovski calls a "weird-looking" spectrum. But the team observed the target a number of times over several months and noted no change...
...North Korea is expected to test-launch a ballistic missile that could finger the very outer edges of America. Which isn't to say that anyone thinks Pyongyang will blast Anchorage anytime soon, but just testing that kind of missile--and then putting it up for sale on the international arms market--is enough to make huge swaths of the world very nervous. It's a perfect setup for high-priced extortion, and last week diplomats were struggling: Do we let the North Koreans launch, or can we buy them off? On the brink of collapse and with its people...
...solar panels needed to supply Cassini at that distance would have to be far too large for such a mission. Other than plutonium generators, says physicist James Van Allen, discoverer of Earth's radiation belts, "there is no practical source of electrical power for spacecraft that go to the outer planets." Controllers at the Jet Propulsion Laboratory report that Cassini, having already flown more than a billion miles, is in excellent shape. All systems are operating well, and the craft is on course for a flyby of home...

...puts on two suits, one over the other, both made of materials that seal out dust but trap heat. Then he wraps his wrists and ankles, pulls a rubber respirator over his head and climbs more than 200 ft. into the narrow space between the Capitol's inner and outer domes. Gilbo, who lives in Georgetown, Mass., is part of a 10-man crew removing poisonous lead paint from cast-iron walls in temperatures that regularly soar above 100[degrees]F. "It's a pretty hostile environment," says Gilbo, who says he sweats off 4 lbs. during every 12-hour...
