...plays tricks with weather; Wolverine (Hugh Jackman), whose fists contain adamantine blades; Cyclops (James Marsden), with a killer stare; and Rogue (Anna Paquin), whose touch is toxic. Xavier and Dr. Jean Grey (Famke Janssen) battle the bad guys led by Magneto (Ian McKellen) over the fate of the planet--that old thing...
...checked into a hotel a few years ago on the south rim of the Grand Canyon and peered out the window into majestic, blue-ish prehistory--one of the planet's more powerful astonishments. A family checked into the room next door, and a moment later, through the thin walls, we heard the sound of the television coming on. Loud...
Finding liquid water on Mars' surface has never been easy--mostly because it simply can't exist there. The modern-day Martian atmosphere has barely 1% the density of Earth's, and the planet's average temperature hovers around a paralyzing -67[degrees]F. In an environment as harsh as this, any water that did appear would either vaporize into space or simply flash-freeze where it stood. What scientists studying Martian history have always looked for instead are clues that the planet's ancient water left behind--tracks where vanished rivers once flowed, basins where vanished seas once stood...
...three years it has been circling Mars are full of this kind of expected hydro-scarring. But a handful of the pictures took scientists by surprise. In general, the older a Martian formation is, the more likely it is to have been distorted over the eons--smoothed by the planet's periodic windstorms or gouged by the occasional incoming meteor. A few of the newly discovered water channels, however, look as fresh as the day they were formed, leading astonished researchers to conclude that that day may have been remarkably close to the present one. Says Weiler: "The water could...
...long assumed that if underground water was going to bubble up on Mars, it would have to be somewhere in the comparatively balmy equatorial zones, where temperatures at high noon in midsummer may approach a shirtsleeves 68[degrees]F. Almost all the new channels, however, were spotted at the planet's relative extremes--north of 30[degrees] north latitude and south of 30[degrees] south--and all were carved on the cold, shaded sides of slopes...
