There's a lot of comparison with the human species. They are the dominant species on the ocean, just like we are the dominant species on land. They also occupy the entire ocean - 71 percent of the planet, from the Arctic to the Antarctic, which is unusual for a marine mammal. It's a very sophisticated species. But they are called killer whales because they do kill whales...
...Although modern technology has made "exoplanets" commonplace, with almost 350 already known and more found each day, astronomers are still eluded by the holy grail of astrobiology - signs of a planet capable of supporting life like our own. If we hope to find an Earth-like world around another star, we must first be sure we would recognize...
...inexpensive: The whole set-up only cost about $15,000 - next to nothing for a piece of groundbreaking astronomical research. "Earthshine is such a simple idea that we have known about for such a long time," says Langford, "but it makes looking at Earth as a 'prototype' Earth-like planet so easy! An amateur astronomer could definitely take this data...
...Hopeful astronomers are looking toward a NASA mission called the Terrestrial Planet Finder, or TPF - a space-based planet-imaging telescope capable of picking out the faint light of small exoplanets that would otherwise be lost in the glare of their own suns (almost all the exoplanets found so far have been detected indirectly). "Obviously," says astronomer Eric Ford, of the University of Florida, "we're anxious for TPF to be launched...
...some dystopian Horn of Africa version of Waterworld. We see wily corsairs in ragged clothing swarming out of their elusive mother ships, chewing narcotic khat while thumbing GPS phones and grappling hooks. They are not desperate bandits, experts say, rather savvy opportunists in the most lawless corner of the planet. But the pirates have never been the only ones exploiting the vulnerabilities of this troubled failed state - and are, in part, a product of the rest of the world's neglect.
