WASHINGTON, Dec. 20 (Xinhua) -- NASA's Kepler mission has discovered the first Earth-size planets orbiting a sun-like star outside our solar system, the U.S. space agency announce Tuesday.The planets, called Kepler-20e and Kepler-20f, are too close to their star to be in the so-called habitable zone where liquid water could exist on a planet's surface, but they are the smallest exoplanets ever confirmed around a star like our sun, according to NASA.The discovery marks the next important milestone in the ultimate search for planets like Earth. The new planets are thought to be rocky. Kepler-20e is slightly smaller than Venus, measuring 0.87 times the radius of Earth. Kepler-20f is slightly larger than Earth, measuring 1.03 times its radius. Both planets reside in a five-planet system called Kepler-20, approximately 1, 000 light-years away in the constellation Lyra.Kepler-20e orbits its parent star every 6.1 days and Kepler-20f every 19.6 days. These short orbital periods mean very hot, inhospitable worlds. Kepler-20f, at 800 degrees Fahrenheit, is similar to an average day on the planet Mercury. The surface temperature of Kepler-20e, at more than 1,400 degrees Fahrenheit, would melt glass."The primary goal of the Kepler mission is to find Earth-sized planets in the habitable zone," said Francois Fressin of the Harvard-Smithsonian Center for Astrophysics, lead author of a new study published in the journal Nature. "This discovery demonstrates for the first time that Earth-size planets exist around other stars, and that we are able to detect them."The Kepler-20 system includes three other planets that are larger than Earth but smaller than Neptune. Kepler-20b, the closest planet, Kepler-20c, the third planet, and Kepler-20d, the fifth planet, orbit their star every 3.7, 10.9 and 77.6 days. All five planets have orbits lying roughly within Mercury's orbit in our solar system. The host star belongs to the same G-type class as our sun, although it is slightly smaller and cooler.

BEIJING, Dec. 30 (Xinhua) -- China will push to properly resolve the case of a Chinese skipper indicted by Japan, the Foreign Ministry said Friday.Spokesman Hong Lei said this is a common fishing case, and the Chinese embassy in Japan has dispatched officials to visit the skipper.China requests that Japan ensure the rights of the Chinese skipper, Hong said, and China is communicating closely with Japan in order to properly resolve the case.The Chinese government has been requiring fishermen to fish legally, Hong said, adding that the competent authorities have done a lot in this area, and he promised to promote the management and education of Chinese fishermen.Japanese prosecutors have indicted the captain of a Chinese fishing boat for illegally operating in Japanese waters, a local official said Friday.The Nagasaki District Public Prosecutors Office has finalized its case against Zhong Jinyin, 39, following his December 20 arrest near islands off southwest Japan, according to the official.The prosecutors have not indicated whether the skipper has admitted to the charge.

BEIJING, Dec. 30 (Xinhua) -- Chinese State Councilor Dai Bingguo and U.S. National Security Advisor Tom Donilon held a telephone conversation on China-U.S. relations on Friday.The two senior officials reviewed recent developments in China-U.S. relations and agreed to carry out in 2012 the important consensus reached between the heads of state of the two countries.They also pledged to strengthen dialogue, mutual trust and cooperation, properly handle disputes, and promote a healthy and steady development of China-U.S. relations.Dai and Donilon also exchanged views on other issues of common concern.

BEIJING/CHONGQING, Oct. 16 (Xinhua) -- A team of Chinese and American scientists have discovered the world's only evidence of co-existing human beings and dinosaur tracks in a remote county in southwest China's Chongqing Municipality, according to a paper published Saturday in the Geological Bulletin of China, a Chinese core academic journal.Qijiang County's Lianhua Baozhai, which means "Lotus Mountain Fortress" in Chinese, has a large number of dinosaur tracks as well as a well-preserved fortress and historical epigraph, forming a direct line of evidence that ancient Chinese people built a residence and lived there for a long time, said Xing Lida, one of three researchers with the project as well as a doctoral degree candidate with the Department of Biological Sciences of the University of Alberta in Canada.Chinese people could have lived here for more than 700 years, and the mud cracks, ripple marks and duck-billed dinosaur tracks were considered by them to be lotus leaf veins, water environment and lotus, respectively, which is why they named it the Lotus Mountain Fortress, Xing Lida told Xinhua."Research shows that dinosaur tracks impacted ancient Chinese place names and folklore, so place names and folklore can be major clues for us in tracing dinosaur tracks," Xing said.According to the paper, the Lotus Mountain Fortress dinosaur tracks, the largest track group of cretaceous dinosaurs in southwestern China, contains 350 to 400 footprints that had been preserved in many ways, including concave footprints, convex footprints and multilayered footprints.

BEIJING, Jan. 22 (Xinhua) -- China restored 23,000 hectares of wetlands in 2011, according to the latest figures from the State Forestry Administration (SFA).An SFA spokesman said China reinforced wetland protection in 2011 by increasing subsidies in protecting wetlands. In the year the country carried out 42 wetland protection projects, increased 330,000 hectares of protected wetland areas, added four wetlands of international importance and 68 national wetland parks.The spokesman said in 2012 the country will further step up wetland protection and restoration, finish the second national wetland resources investigation and carry out pilot projects in assessing healthy conditions of the wetland ecological system.So far China has built more than 550 wetland natural reserves, 37 wetlands of international importance, which were listed in the Ramsar international wetland convention, and 100 national wetland parks. About half of the country's natural wetlands have been brought under effective protection, the SFA said.
