...edge of the universe, two stars the size of Earth, made of million-degree diamond and oxygen, smash together in an explosion that outshines their entire galaxy. The shrapnel from explosions like that one are thought to have made everything we know on Earth??including us—and could provide clues to the ultimate fate of the universe. And last week, a team led by Harvard astronomers announced they had seen such shrapnel. What the team observed was a stellar explosion, called a supernova, that was caused by the merger and collision of two white dwarf stars?...
...politics—it serves as a corrective to abstract cold reason gone astray. But it is nevertheless extremely powerful and should be used wisely. We should hope and pray for the abject of Darfur or Myanmar; but we cannot immanentize the eschaton—bring Heaven to earth??in hoping to ameliorate theirs and every other situation needing improvement.

To do otherwise, to insist that we can save the world and right every...

Teresa Kerry has long been noted for her commitment to environmental philanthropy, particularly for her funding of these causes in Pittsburgh and southwestern Pennsylvania. Undoubtedly, many of the individuals discussed in “This Moment on Earth?? are ones she has supported through her numerous foundations. In contrast, the Senator, who has spent 22 years in Washington, provides virtually none of the insights he has gained or the sorts of policy proposals he and his colleagues are considering.

When I arrived at the event held in Harvard Square’s First Parish Church, I was startled to find that scores of seats were empty. Even in the most liberal state in the Union’s most liberal city, John Kerry was unable to draw anywhere near a sell-out crowd...
...light, will replace whiter snow and ice, which reflect more rays back to space. Like a dark-colored car hood on a hot day, a dark-colored earth will warm. The group’s computer modeling experiments show that the localized warming due to the change in the earth??s surface reflectivity (called its “albedo”) would be greater than the global cooling due to the carbon dioxide the trees absorb...
