LOS ANGELES, April 7 (Xinhua) -- Using NASA's Galaxy Evolution Explorer (GEE) satellite, U.S. astronomers are hunting for nearby, hard-to-see stars which could very well be home to the easiest-to-see alien planets, it was announced on Thursday.U.S. astronomers are ferreting out the new targets after the glare of bright, shining stars has frustrated most efforts at visualizing distant worlds, NASA's Jet Propulsion Laboratory (JPL) said.So far, only a handful of distant planets, or exoplanets, have been directly imaged. Small, newborn stars are less blinding, making the planets easier to see, but the fact that these stars are dim means they are hard to find in the first place."Fortunately, the young stars emit more ultraviolet light than their older counterparts, which makes them conspicuous to the ultraviolet-detecting GEE," JPL said in a press release."We've discovered a new technique of using ultraviolet light to search for young, low-mass stars near the Earth," said David Rodriguez, a graduate student of astronomy at University of Californian, Los Angeles. "These young stars make excellent targets for future direct imaging of exoplanets."Young stars, like human children, tend to be a bit unruly -- they spout a greater proportion of energetic X-rays and ultraviolet light than more mature stars. In some cases, X-ray surveys can pick out these youngsters due to the "racket" they cause. However, many smaller, less "noisy" baby stars perfect for exoplanet imaging studies have gone undetected except in the most detailed X-ray surveys. To date, such surveys have covered only a small percentage of the sky, according to JPL in Pasadena, Los Angeles.Rodriguez and his team figured that the GEE, which has scanned about three-quarters of the sky in ultraviolet light, could fill this gap.Astronomers compared readings from the telescope with optical and infrared data to look for the telltale signature of rambunctious junior stars. Follow-up observations of 24 candidates identified in this manner determined that 17 of the stars showed clear signs of youth, validating the team's approach, JPL said."The Galaxy Evolution Explorer can readily select young, low- mass stars that are too faint to turn up in all-sky X-ray surveys, which makes the telescope an incredibly useful tool," Rodriguez said in the release.

TOKYO, March 20 (Xinhua) -- Traces of radioactive iodine had been detected in Tokyo and the surrounding Kanto region, according to the results of an investigation of radioactivity in precipitation and dust conducted by the government, local media reported on Sunday.Radioactive iodine was found in Tokyo, Saitama, Chiba, Yamanashi, Tochigi and Gunma prefectures, the Kyodo News said, citing the Ministry of Education, Culture, Sports, Science and Technology. The ministry added that the levels detected in the investigation alone would not affect human health.An employee of Yamagata city office holds a Geiger counter to detect radiation when evacuees from the vicinity of Fukushima nuclear plant wish to be screened upon their arrival at an evacuation centre set in a gymnasium in Yamagata, northern Japan March 19, 2011, eight days after Japan's devastating earthquake and tsunami.The investigation was carried out following the nuclear crisis at the Fukushima Daiichi nuclear power plant, the government said Sunday.The ministry said that a separate research has already shown that radioactive materials in the air and tap water in Tokyo and the five prefectures pose no threat to human health, according to Kyodo News report.

DAVOS, Switzerland, Jan. 29 (Xinhua) -- China is ready to push the decade-long Doha Round negotiations for a final success, Chinese Minister of Commerce Chen Deming said here on Saturday.Speaking at the World Trade Organization (WTO) Mini-Ministerial Meeting which brought together representatives from over 20 major trading powers, Chen said that China is ready to collaborate with other WTO members in a practical and proactive manner so as to draw a successful conclusion of the Doha Round talks by the end of 2011.A rapid conclusion of the negotiations, Chen said, will be beneficial to global economic recovery, which is to the interest of all.The commerce minister acknowledged the year 2011 as a "window of opportunity," albeit a narrow one."China will give support to the roadmap proposed by WTO Director-General Pascal Lamy," he said, adding that the country is willing to act vigorously to push forward the negotiation process.To ensure that an early final deal could be in reach, Chen said, parties should set goals in a practical manner, in accordance with the ambition level, and stick to what has been achieved as well as the Doha Development Agenda (DDA), while focusing primarily on pending issues.Held on the sidelines of the annual World Economic Forum, the WTO Mini-Ministerial Meeting is an annual event under the auspices of the Swiss Federal Government.Chen on Friday also joined discussions with his counterparts from the emerging club -- India, Brazil and South Africa, before attending the trade G7 meeting, consisting of Australia, Brazil, China, the European Union, India, Japan and the United States.

BRASILIA, March 15 (Xinhua) -- A nationwide program aimed at providing internet access to 80 percent of the country's population by 2014 is forging ahead in Brazil, Communications Minister Paulo Bernardo said on Tuesday.The National Broadband Plan (PNBL), with participation of 13 ministries, is coordinated by Bernardo, who explained details about the project on Tuesday along with Joao Santana, president of Telebras, the state-owned enterprise responsible for managing the project.The authorities have criticized companies that offer internet service for failing to spread internet use in Brazil, offering an expensive service with prices amounting to about 50 U.S. dollars monthly, inaccessible to low-income families."We ended 2010 with 34 percent of Brazilian households with Internet access, and service is also very poor. Almost half of connections are of 256 mbps. We are out-of-date, with the aggravating circumstance that the connections are very expensive," Bernardo said.To speed up the process, the government started negotiating with concessionaire phone companies to improve the service quality and lower the price to about 30 reais (18 dollars), which would allow 80 percent of the population to access internet."During (former president) Lula da Silva's government, we developed a program to interconnect all schools with internet access, but we also want the private sector to do its share," he said.

WASHINGTON, May 25 (Xinhua) -- Two U.S. astronauts conducted the third of four scheduled spacewalks for space shuttle Endeavour 's STS-134 mission on Wednesday morning, the U.S. National Aeronautics and Space Administration (NASA) announced.Endeavour's mission specialists Drew Feustel and Mike Fincke completed a six-hour-54-minute spacewalk at 8:37 a.m. EDT (1437 GMT). They completed all planned tasks, installing cables to increase redundancy for the power system on the Russian segment of the station, completing the external wireless antenna system work Feustel and Greg Chamitoff began during the first spacewalk, and installing a power and data grapple fixture to Zarya. The fixture will allow the station's robotic arm to "walk" to the Russian segment, extending its reach by using that grapple fixture as a base.It was the 247th spacewalk conducted by U.S. astronauts, and the 158th in support of space station assembly and maintenance, totaling 995 hours and 13 minutes. If everything goes as planned, the 1,000th hour of space station assembly and maintenance will be logged on Friday.Endeavour lifted off on May 16 from the Kennedy Space Center in Florida, to deliver to the International Space Station a 2-billion- dollar, multinational particle detector known as the Alpha Magnetic Spectrometer (AMS).AMS, a particle physics detector, is designed to search for various types of unusual matter by measuring cosmic rays. Its experiments are designed to help researchers study the formation of the universe and search for evidence of dark matter, strange matter and antimatter.NASA's 30-year-old shuttle program is ending due to high operating costs. The Obama administration wants to spur private companies to get into the space taxi business, freeing NASA to focus on deep space exploration and new technology development.There were initially five space shuttles in the fleet -- Challenger exploded shortly after liftoff in 1986 and Columbia disintegrated on its way back to Earth in 2003. Discovery retired earlier this year, while Endeavour is currently on its final mission. A last mission for Atlantis is scheduled for July, though funding for Atlantis remains in question.The sixth shuttle, Enterprise, did test flights in the atmosphere but was never flown into space. It is already on display at a museum outside Washington.When the U.S. space shuttle program officially ends later this year, the Russian space program's Soyuz capsule will be the only method for transporting astronauts to and from the station.
