JIUQUAN Cheap Rudy Gay Shirt , Feb. 2 (Xinhua) -- China's first shared education satellite, Young Pioneer 1, carried by the Long March-2D rocket, was launched into space from Jiuquan Satellite Launch Center Friday afternoon.
The 3-kg CubeSat (100 * 100 * 340mm) Cheap Pau Gasol Shirt , Young Pioneer 1, enters an orbit of 502 km above the Earth. The rocket also carried Zhangheng 1, an electromagnetic satellite to study earthquake data, and five other miniaturized satellites.
Young Pioneer 1 was manufactured and tested by Commsat Cheap LaMarcus Aldridge Shirt , a Beijing-based private satellite company funded by the Xi'an Institute of Optics and Precision Mechanics under the Chinese Academy of Sciences (CAS).
It will perform wireless storage and transmission of radio waves at UV frequency, space imaging and the verification of user links to the Internet of Things, said Xie Tao, founder and CEO of Commsat.
After in-orbit tests Cheap David Robinson Shirt , Young Pioneer 1 will share its data resources with primary and secondary schools and other education institutions equipped with sub-stations in China. It will provide students with experiences like wireless communication and space photography, Xie said.
LOS ANGELES, Jan. 31 (Xinhua) -- The existence of large numbers of molecules in winds powered by supermassive black holes at the centers of galaxies has puzzled astronomers more than a decade. New theory predicts that molecules in black hole winds are not survivors of the heat of the energetic outflows at all, but brand-new molecules.
Molecules trace the coldest parts of space Cheap Tim Duncan Shirt , and black holes are the most energetic phenomena in the universe, so finding molecules in black hole winds was like discovering ice in a furnace.
Researchers in Northwestern University's Center for Interdisciplinary Research and Exploration in Astrophysics (CIERA) predict that these molecules are born in the winds with unique properties that enable them to adapt to and thrive in the hostile environment.
The theory, published in the current issue of Monthly Notices of the Royal Astronomical Society, is the work of Lindheimer post-doctoral fellow Alexander Richings Cheap Kawhi Leonard Shirt , who developed the computer code that, for the first time, modeled the detailed chemical processes that occur in interstellar gas accelerated by radiation emitted during the growth of supermassive black holes.
"When a black hole wind sweeps up gas from its host galaxy, the gas is heated to high temperatures Cheap Joffrey Lauvergne Jersey , which destroy any existing molecules," Richings was quoted as saying in a statement. "By modeling the molecular chemistry in computer simulations of black hole winds, we found that this swept-up gas can subsequently cool and form new molecules."
This theory answers questions raised by previous observations made with several cutting-edge astronomical observatories including the Herschel Space Observatory and the Atacama Large Millimeter Array, a powerful radio telescope located in Chile.
New stars form from molecular gas Cheap Manu Ginobili Jersey , so the new theory of molecule formation helps explain the formation of new stars in winds, according to the new study.
"This is the first time that the molecule formation process has been simulated in full detail, and in our view, it is a very compelling explanation for the observation that molecules are ubiquitous in supermassive black hole winds Cheap Danny Green Jersey , which has been one of the major outstanding problems in the field," said co-author Claude-Andre Faucher-Giguere, who studies galaxy formation and evolution as an assistant professor in Northwestern's Weinberg College of Arts and Sciences.
Compared to pre-existing molecules, researchers believe that the new molecules formed in the winds are warmer and brighter in infrared radiation.
The new theory will be put to the test when the U.S. National Aeronautics and Space Administration (NASA) launches the James Webb Space Telescope in spring 2019. If the theory is correct Cheap Tony Parker Jersey , the telescope will be able to map black hole outflows in detail using infrared radiation, researchers say.

CAIRO, Jan. 18 (Xinhua) -- Residents living in the neighborhood of Abu Rawash, just a few kilometers from the Giza Pyramids, are known for hunting animals and raising reptiles.
One Egyptian hunter, Salah Tolba, decided to turn his hobby into an animal exhibition business via a rare licensed private zoo.
Africano Tolba Village is a private zoo established by 50-year-old hunter Salah Tolba.
Two adjacent large cages containing a lion and two lionesses are featured in the center of the zoo's open yard, surrounded by several cages of various animals, reptiles and birds.
"I inherited the hunting hobby from my father and grandfathers and establishing this zoo had always been a dream of mine. I have 20 reptile species and between 10 to 15 other animal species in my zoo," Tolba told Xinhua at his private zoo, noting that his family has been in this business for almost 200 years.
Tolba said he received the license to establish the zoo after several committees from the General Authority for Veterinary Services and the Ministry of Environment checked his place to ensure it met the required qualifications.
