Nasa 'smallsats' open up new planetary frontier Nasa is planning a series of small satellite missions that could open up new ways of exploring the Solar System. James Green, head of planetary science at Nasa, told BBC News that the agency was investing in the technology and looking at how best it coul...

NGC 6349 (also MCG 6-38-16 and PGC 60060) is a magnitude +14.3 spiral galaxy located 531 million light-years away in the constellation Hercules. The galaxy forms an optical double galaxy with NGC 6351. The galaxy was discovered by French astronomer Edouard Stephan using a 80.01 cm (31.5 inch) refl...

ESA's comet chaser mission Rosetta took these infrared and visible images of Earth and the Moon, during the Earth fly-by of 4/5 March 2005 while on its way to Comet 67P/Churyumov-Gerasimenko. [img]http://img.photobucket.co...

In the ESA Swarm mission in 2010, GPS antennas will measure the Earths magnetic field with extreme accuracy. Factors such as the right position on the satellite are particularly crucial. A new software program can simulate complex antenna systems, saving time and money. They are due to swarm out in...

New sunspot on the eastern limb captured with a 100mm f5 Helios refractor and Vesta pro webcam.

Earth's magnetic field perturbed by 'electric oceans', claims researcher In a radical rethink of accepted geophysics, new research in the US links variations in the Earth's magnetic field with the ebb and flow of the world's oceans. Given the practical importance of these field variations in nav...

Planet with 'temperate' climate found European astronomers have found a planet outside our solar system with a relatively moderate temperature, far cooler than other "exoplanets" discovered to date. The planet Corot-9b has an estimated surface temperature between 160 C and -20 C. I...

Title: KIC 7385478: An eclipsing binary with a gamma Doradus component Author: Orkun Ozdarcan, Hasan Ali Dal We present spectroscopic and photometric analysis of the eclipsing binary KIC\,7385478. We find that the system is formed by F1V + K4III-IV components. Combining results from analysis o...
