...grieves me so much that we had not told the American people how tough and difficult this task would be." --JOHN McCAIN, Republican Senator from Arizona, criticizing the Bush Administration for "underestimating the size of the task" in Iraq and leading people to think it would be "some kind of day at the beach." The White House replied that President Bush had been open about the difficulty of the mission from the start...
...full answer may have to wait for a new generation of telescopes expected to come on line within the next decade. In astronomy, size matters, especially for faraway objects. The bigger a telescope, the more of a distant galaxy's meager light it can gather--just as a swimming pool catches more rain than a bucket. So astronomers are looking forward to a ground-based monster with nearly 10 times the light-gathering area of the Keck, a space telescope more than 10 times as big as the Hubble and several radio telescopes with unprecedented sensitivity. Meanwhile, using the basic...
...time, though, they served simply to change the chemistry of the clouds, allowing them to collapse into far smaller objects than they could before. The second generation of stars, incorporating the ashes of the first, arose almost immediately. They were much more like the sun, in both composition and size. And like the sun, they would have started out generating lots of ultraviolet light before settling down to a more sedate existence...
...event, the accepted scenario is that this new generation of small galaxies, containing no more than a million second-generation stars, gradually collided, merging to form ever bigger objects that eventually reached the size of the Milky Way. One piece of evidence: the faintest and oldest galaxies found in any great number by the Hubble telescope tend to be small and irregular in shape, not the majestic spirals and huge elliptical galaxies that formed later. Another hint that the merger theory is correct is that the collisions are still going on today. Astronomers can see hundreds of colliding galaxies...
...Pentagon has nine combatant commands, with responsibility for Africa awkwardly divided among three: the European Command, Pacific Command and Central Command (Centcom); the last is responsible for Iraq and Afghanistan. An African Command would eliminate that cumbersome structure. But critics say it could compound an existing problem: "The size and number of headquarters already are skewed too far in favor of 'tail' at the expense of war-fighting 'teeth,'" says a retired military officer...
