The search for life in the universe took a step forward last month with the opening of the Allen Telescope Array(艾伦望远镜阵列) in Hat Creek, California. The telescopes were partly made possible by a gift of twenty-five million dollars from Paul Allen. The total cost of the project is already fifty million dollars.
At present, there are 42 radio telescopes working at the Hat Creek observatory. The signals they receive are combined to create what is equal to a single, very large telescope. The telescope will be used to observe objects like exploding stars, black holes and other objects that are predicted but have not yet been observed. Seth Shostak of the SETI Institute says this is the first telescope whose main purpose is to search for signals from intelligent life in space. The SETI Institute is based in Mountain View, California. The organization supports the search for other life forms in the universe.
What makes the Allen Telescope Array unusual is that it can collect and study information from a wide area of the sky. In addition, the 42 telescopes can study information about several projects at the same time. That means studies of large areas of the sky can be made faster than ever before.
Some officials think the Allen Telescope Array will be completed in three more years. 350 individual radio telescopes are planned. The new abilities of the Allen Telescope Array will make searching for stars similar to the sun much faster.
An earlier search by SETI, Project Phoenix, studied about 800 stars to a distance of 240 light years. The project ended in 2004. With the Allen Telescope Array, astronomers hope to gather thousands of times more information in the search for life beyond our planet.

XIANGNING, Shanxi - The number of people trapped underground after a coal mine flooding in north China's Shanxi Province was revised -- for a second time -- to 153 from 123, rescuers said late Sunday night.
Investigations showed that 261 workers were in the pit of Wangjialing Coal Mine under construction when underground water gushed in at about 1:40 pm. Of them, 108 were lifted safely to the ground while 153 others trapped in the shaft, according to the rescue headquarters.
Most of the trapped are migrant workers from Shanxi, Hebei, Hunan and Guizhou provinces," a rescuer said.
The exact number of people trapped is still being checked.
Soon after the accident happened, the Shanxi Provincial Work Safety Administration and the Shanxi Provincial Emergency Affairs Office said 152 people were trapped underground, but officials later changed the figure to 123.
Rescuers are struggling to save the trapped people, and local authorities are investigating the cause of the accident.
President Hu Jintao and Premier Wen Jiabao ordered local authorities to spare no effort to save the trapped while guarding against secondary accidents.
Vice Premier Zhang Dejiang rushed to the site late Sunday to oversee the search and rescue operation.
The mine, sitting astride Xiangning County of Linfen City and Hejin City of Yuncheng City, covers about 180 square kilometers.
The mining zone boasts more than 2.3 billion tonnes of coal reserves, including nearly 1.04 billion tonnes of proved reserves, according to the company's official website.It is now under infrastructure construction and is expected to produce 6 million tonnes of coal annually once put into operation.
The mine, affiliated to the state-owned Huajin Coking Coal Co. Ltd., is a major project approved by the provincial government.

More Americans are Googling themselves ------ and many are checking out their friends, co-workers and romantic interests, too.
In a report Sunday, the Pew Internet and American Life Project said 47 percent of U.S. adult Internet users have looked for information about themselves through Google or another search engine.
That is more than twice the 22 percent of users who did in 2002, but Pew senior research specialist Mary Madden was surprised the growth wasn't higher.
"Yes it's doubled, but many Internet users have never done this simple act of plugging their name with search engines," she said.
Americans under 50 and those with more education and income were more likely to self-Google because their jobs demand a certain online persona.
Meanwhile, Pew found that 53 percent of adult Internet users admit looking up information about someone else, not including celebrities.
Often, it's to find someone they have lost touch with. But looking up information about friends, relatives, colleagues and neighbors also was common.
Although men and women equally searched for online information about themselves, women were slightly more likely to look up information about someone they are dating.
In many cases, the search is done to find someone's contact information. But a third of those who have conducted searches on others have looked for public records, such as bankruptcies(破产) and divorce (离婚)proceedings. A similar number have searched for someone else's photo.
Few Internet users say they Google themselves regularly —— about three-quarters of self-searchers say they have done so only once or twice. And most who have done so consider what they find accurate.
Pew also found that teens were more likely than adults to restrict who can see their information at an online hangout(常去之处) like Facebook or News Corp's MySpace.
