Researchers Show Component Of Mothballs Is Present In Deep-Space Clouds Athens GA (SPX) Sep 03, 2009 ![]() Is Cygnus X-1 Still A Star ![]() Since its discovery 45 years ago, Cygnus X-1 has been one of the most intensively studied cosmic X-ray sources. About a decade after its discovery, Cygnus X-1 secured a place in the history of astronomy when a combination of X-ray and optical observations led to the conclusion that it was a black hole, the first such identification. The Cygnus X-1 system consists of a black hole with a mas ... more

Indian satellite confirmed US moon landing: scientist![]() India's first lunar mission has captured images of the landing site of the Apollo 15 craft, debunking theories that the US mission was a hoax, the country's state-run space agency said Wednesday. "The images captured by a hyper-spectral camera fitted as a part of Chandrayaan-I... has reconfirmed the veracity of the Apollo 15 mission," said Prakash Chauhan, from the Indian Space Research Orga ... more Chandrayaan-1 Confirms Lunar Magma Ocean Hypo ![]() India's maiden moon mission, Chandrayaan-1, in one of its vital findings, has endorsed the lunar magma ocean hypothesis, helping the scientists better understand the history of the satellite, a NASA scientist said here today. Speaking at an international conference here, Carle Pieters, a professor at the US-based Brown University, who was associated with the Chandrayaan as a moon mineral m ... more Precise Radio Measurements Advance Gravitational Physics ![]() Scientists using a continent-wide array of radio telescopes have made an extremely precise measurement of the curvature of space caused by the Suns gravity, and their technique promises a major contribution to a frontier area of basic physics. "Measuring the curvature of space caused by gravity is one of the most sensitive ways to learn how Einsteins theory ... more |

Small Fluctuations In Solar Activity, Large Influence On The Climate![]() Our sun does not radiate evenly. The best known example of radiation fluctuations is the famous 11-year cycle of sun spots. Nobody denies its influence on the natural climate variability, but climate models have, to-date, not been able to satisfactorily reconstruct its impact on climate activity. Researchers from the USA and from Germany have now, for the first time, successfully simulated ... more Honey, I Blew Up The Tokamak ![]() Magnetic reconnection could be the Universe's favorite way to make things explode. It operates anywhere magnetic fields pervade space--which is to say almost everywhere. On the sun magnetic reconnection causes solar flares as powerful as a billion atomic bombs. In Earth's atmosphere, it fuels magnetic storms and auroras. In laboratories, it can cause big problems in fusion reactors. It's ... more Trifid Triple Threat ![]() Astronomers at the European Southern Observatory (ESO), of which the UK's Science and Technology Facilities Council is a partner, have captured a stunning new image of the Trifid Nebula, showing just why it is a firm favorite of astronomers, amateur and professional alike. This massive star factory is so named for the dark dust bands that trisect its glowing heart, and is a rare ... more |
