...Tuesday, a team of European astronomers announced that they had not only found a new planet circling a comparatively nearby star in the constellation Libra, but that that planet is unexpectedly Earth-like. Like Earth, it orbits a comfortable distance from its sun; like Earth, it maintains a surface temperature somewhere between 32 and 104 degrees Fahrenheit. Most importantly, like Earth, it could easily harbor surface water. In the biological arithmetic we know best, warmth and water often equal life...
...terrestrial feel, the new planet - unpoetically dubbed Gliese 581c - has a decidedly extraterrestrial look. It is probably more than 1.5 times the diameter of Earth and five times heavier. But unlike our world, which orbits a comfortable 92.9 million miles from the flames of the sun, 581c hovers just 7 million miles from its home star. What prevents it from being incinerated like a match head is that its star is a red dwarf, only about one one-hundredth as bright as the sun. The dim light coupled with the planet's close proximity places it in what astronomers call...

Kerry and Heinz Kerry spoke at the event, organized by the Harvard Book Store, to promote their new book, “This Moment on Earth: Today’s New Enviromentalists and their Vision for the Future.” “We have to embarrass people being dumb and greedy,” Heinz Kerry said. Kerry said he and Heinz Kerry chose the title of their book because U.S. policy...
Kerry appeared fairly polished during his opening remarks, even garnering a few obligatory chuckles from the crowd when he sardonically wisecracked that there is “a flat-earth caucus in Congress.” Yet while those in attendance were respectful, it was obvious from the tepid applause that the Kerrys garnered for even red meat rhetoric that the audience wasn’t particularly enthused by the issues addressed...
