...marched in early on, we wouldn’t have a planet to live on,” Charbonneau said. With two planetary discoveries published within a week of each other, and a handful detected in previous years, the CfA is positioning itself at the forefront of the search for planets outside our solar system. According to Stephen S. Murray, CfA’s deputy director for science, the center is also involved in NASA’s Kepler Mission, which will send a telescope to search for habitable planets. TrES-2 is in the same region that Kepler will...
...from space using the Hubble and the Spitzer telescopes to get better measurements on the transit curves. With HAT generating additional planetary candidates, Noyes believes that more and more transiting planets will be detected. “We and several other groups have now learned enough of how to search for planets with small telescopes,” he said. “We’re learning how to search for needles in haystacks.” In the same week, Assistant Professor of Astronomy David Charbonneau led a team of Harvard astronomers in detecting a planet larger than...
...Soul" [aug. 28], on the growth of Christianity in China, implied that Chinese Communist Party control over religion might be relaxing. But given the party's history of infiltrating seemingly safe social networks, it is likely that those house churches are no more beyond government control than are Internet search engines or chat rooms. In a country where politically incorrect websites are routinely shut down and the government uses text messages as warnings against public demonstrations and has a history of using neighbors to spy on one another, can Chinese Christians really think that Big Brother isn't watching them...
...VoIP provides better cover than text-based communications because live conversations, when converted to digital bits for transmission on the Internet, are harder than e-mail to search for offensive words. Voice information is generally discarded once a call is over, while e-mail is stored indefinitely on servers, making it easier to trace the authors. Services like Skype also use encryption technology to scramble calls, so eavesdroppers can't decipher what's being said without a software "key" to decode the transmission. There's another benefit, too: in Vietnam's crowded Internet caf?s, it's tough for police...
...American women in the 19th and 20th centuries, Higginbotham became the second black woman to be tenured in the Faculty of Arts and Sciences (FAS) when she arrived at Harvard in 1994 from the University of Pennsylvania. Currently, she also sits on the faculty advisory group of the Presidential Search Committee...
