Canadian solar project wins top environment award
Canada has scooped a top prize for environmental protection awarded by the Austrian foundation Energy Globe for a community project that uses solar-powered heating to warm local houses.
Voyager 2 to switch to backup thruster set
(PhysOrg.com) -- NASA's Deep Space Network personnel sent commands to the Voyager 2 spacecraft Nov. 4 to switch to the backup set of thrusters that controls the roll of the spacecraft. Confirmation was received ...
Earth's magnetosphere behaves like a sieve
ESA's quartet of satellites studying Earth's magnetosphere, Cluster, has discovered that our protective magnetic bubble lets the solar wind in under a wider range of conditions than previously believed.
New evidence to solve the mystery of the 'eclipse wind'
(PhysOrg.com) -- Solar eclipses are not only amazing celestial spectacles - they also cause subtle changes to the weather here on Planet Earth, according to meteorologists.
Heating the solar wind
(Phys.org) —The Sun glows with a surface temperature of about 5500 degrees Celsius. Meanwhile its hot outer layer (the corona) has a temperature of over a million degrees, and ejects a wind of charged particles ...
Sun-powered plane trip delayed by wind
The Swiss sun-powered aircraft Solar Impulse has been delayed by strong winds during a stop-off on its first planned intercontinental flight, organisers said on Monday.
Estimating the magnetic field of an exoplanet
Scientists developed a new method which allows to estimate the magnetic field of a distant exoplanet, i.e., a planet, which is located outside the Solar system and orbits a different star. Moreover, they ...
TWINS/IBEX spacecraft observed impact of powerful solar storm from inside and outside Earth's magnetosphere
(PhysOrg.com) -- For the first time, instrumentation aboard two NASA missions operating from complementary vantage points watched as a powerful solar storm spewed a two million-mile-per-hour stream of charged ...
Night-time view of Aurora
(Phys.org)—Overnight on October 4-5, 2012, a mass of energetic particles from the atmosphere of the Sun were flung out into space, a phenomenon known as a coronal mass ejection. Three days later, the storm ...
Electric solar wind sail could make bidirectional manned Mars flights economically feasible
The E-sail is a novel propellantless technology that was invented in Finland in 2006. The E-sail utilises long, charged tethers to convert natural solar wind momentum flux into spacecraft thrust.
Eclipses' effect on wind revealed
Solar eclipses don't just turn the lights out; they also make the wind slow down and change direction.
The solar wind is swirly
(Phys.org)—Using ESA's Cluster quartet of satellites as a space plasma microscope, scientists have zoomed in on the solar wind to reveal the finest detail yet, finding tiny turbulent swirls that could play ...
The high winds of the upper atmosphere contain less renewable energy than previously assumed
It seems that the energy mix of the future will have to differ from the current suggestions of some visionaries. This is because the jet streams that sweep the upper atmosphere with high winds would yield ...
Solar power to eclipse nuclear in Romania by 2016
Solar power will eclipse nuclear energy in 2016 in Romania if investment in photovoltaic plants continues at the current pace, official figures released on Monday showed.
