Fully renewable electricity could be competitive
(Phys.org) —A carbon price of between $50 and $100 per tonne of carbon dioxide would make coal-fired and gas-fired power less economical than renewable electricity, a UNSW study shows.
Spectral analysis reveals Moon might have had water when it was formed
The mysterious case of asteroid Oljato's magnetic disturbance
(Phys.org)—Back in the 1980s, the arrival of asteroid 2201 Oljato inside the orbit of Venus heralded a flurry of magnetic activity. Now, results from ESA's Venus Express spacecraft suggest that Oljato has ...
Morocco to harness the wind in energy hunt
Morocco is ploughing ahead with a programme to boost wind energy production, particularly in the southern Tarfaya region, where Africa's largest wind farm is set to open in 2014.
Stellar winds may electrify exoplanets
(Phys.org) —The strangest class of exoplanets found to date might be even stranger than astronomers have thought. A new model suggests that they are partially heated by electric currents linked to their host stars. Florida ...
Breaking the barriers for low-cost energy storage
A team of researchers has developed a cheap, rechargeable and eco-friendly battery that could be used to store energy at solar power plants for a rainy day.
Massive stellar winds are made of tiny pieces
(Phys.org)—ESA's XMM-Newton space observatory has completed the most detailed study ever of the fierce wind from a giant star, showing for the first time that it is not a uniform breeze but is fragmented ...
Astronomers solve the mystery of stellar 'superwind'
Astronomers at the University of Manchester believe they have found the answer to the mystery of a powerful "superwind" which causes the death of stars.
A pathway for protons: Efficient delivery to material's center turns oxygen cleanly into water
(Phys.org)—Pushing protons around may sound like a small task, but it is a big part of energy independence for the United States. Moving four relatively large protons to where they are needed is easier ...
NASA and partners to send test solar sail craft into space next year
IBEX spacecraft images the heliotail, revealing an unexpected structure
(Phys.org) —NASA's Interstellar Boundary Explorer (IBEX) spacecraft recently provided the first complete pictures of the solar system's downwind region, revealing a unique and unexpected structure.
Loopholes discovered in Sun's magnetic belt
(Phys.org)—The mystery surrounding how an electrically charged solar wind can be unleashed from around the Sun's equator – an area where strong magnetic fields should strap it to the surface – has ...
Rosetta image demonstrates the unpredictable nature of comets
(Phys.org) —An image snapped earlier this month by ESA's Rosetta spacecraft shows its target comet has quietened, demonstrating the unpredictable nature of these enigmatic objects.
Measuring Mars: The MAVEN magnetometer (w/ video)
When the Mars Atmosphere and Volatile Evolution (MAVEN) mission begins its journey to the Red Planet in 2013, it will carry a sensitive magnetic-field instrument built and tested by a team at NASA's Goddard ...
