 Canadian Space Scope Detects Puzzling Brightness Variations In Dying Star - SpaceDaily  Left:  Full MOST lightcurve obtained for the subdwarf B star PG 0101+039 over 16.9 days starting 28 September 2004. (See larger image.) Each data point corresponds to the relative brightness of the star at that particular time. The top row covers the first 24-hour period of the run, and the data for subsequent days have been shifted downwards arbitrarily for visualisation purposes. This material was presented to the Canadian Astronomical Society meeting in Montreal, QC on May 15, 2005. Credit: Universite de Montreal and MOST.  Subdwarf B stars are around 5 times hotter than our Sun, and so dense that - at comparable masses - they are about 10 times smaller. They are rather abundant in the night-time sky and dominate the population of bright blue stars. "Asteroseismology lets us probe deep inside stars to reveal their internal composition, an aspect that normally remains hidden even from the world's largest telescopes" explained Suzanna Randall, an astronomy PhD student at the Universite de Montreal, 
Novel Procedure Proposed To Probe The Nature Of Dark Energy - SpaceDaily  Left: The proposed technique will be able to determine if the cosmic acceleration (illustrated) is due to a yet unknown form of Dark Energy in the universe or if it is a signature of a breakdown of Einstein's theory of General Relativity at very large scales of the universe. In order to explain the cosmic acceleration, theoretical cosmologists introduced the notion of a new energy component that would constitute two thirds of the entire energy density of the universe and that is gravitationally repulsive rather than attractive. This component has been termed Dark Energy. Is Dark Energy real? "We don't know," comments Professor David Spergel from Princeton. "It could be a whole new form of energy or the observational signature of the failure of Einstein's theory of General Relativity. Either way, its existence will have profound impact on our understanding of space and time."    

Global Wind Map May Provide Better Locations For Wind Farms - SpaceDaily  Left:  The researchers also found that some of the strongest winds were observed in Northern Europe, along the North Sea, while the southern tip of South America and the Australian island of Tasmania also recorded significant and sustained strong winds at the turbine blade height.  The researchers collected wind speed measurements from approximately 7,500 surface stations and another 500 balloon-launch stations to determine global wind speeds at 80 meters [300 feet] above the ground surface, which is the hub height of modern wind turbines. Such wind speeds at 80 meters, referred to as wind power Class 3, were found in every region of the world, although North America was found to have the greatest wind power potential.
