While the new planet, dubbed GJ 1214b, is too big to be considered Earth-like, it comes pretty close. But GJ 1214b's relatively compact size - smaller than the vast majority of planets identified so far - is only one reason for astronomers' enthusiasm. Another is GJ 1214b's likelihood of bearing the stuff of life: water...
...small, dim, red stars known as M-dwarfs, nearby Earth. M-dwarfs are much more numerous than Sun-like stars; of the 300 stars closest to Earth, says Charbonneau, 220 or so are M-dwarfs. They're also much cooler than Sun-like stars, so their habitable zones are close-in. A planet in the Goldilocks position around an M-dwarf doesn't take a year to orbit, as Earth does; it takes only a few days (1.6 days, in the case of GJ 1214b). So astronomers need to wait only a few days to spot a planet passing...
...yesterday’s e-mail, HUPD advised that students, faculty, and staff be careful while walking throughout campus and surrounding areas. The e-mail also suggested that pedestrians avoid “talking on cell phones, listening to music, or walking too close to persons unnecessarily,” in addition to walking with others and utilizing the shuttle bus whenever possible...
...southernmost reaches of Okinawa Prefecture (it's an hour's flight from Naha to Ishigaki Island and then a 40-minute ferry ride) is covered in mountainous virgin jungle and mangrove forests. Tailored ecotours like those offered at Hirata Tourism's Jungle Adventures, hirata-group.co.jp, allow you to get up close and personal, either on foot or by canoe, with mysterious creatures such as the Chinese box turtle and the indigenous yamaneko wild cat. Abundant reefs and sparkling blue waters have also made the island a playground for scuba divers and snorkelers. And with just 2,000 inhabitants, it feels like...
...ticking for reconciliation. In April, dove-ish Turkish Cypriot leader Mehmet Ali Talat is up for re-election. If peace talks with Greek Cypriot President Demetris Christofias fail to produce any substantive development by then, he is likely to lose to a hard-liner opposed to negotiations. That could close the door indefinitely on what observers agree is the island's latest and best shot at peace in three decades...
