After its launch in February 2007, the group of five satellites in the constellation THEMIS (Time History of Events and Macroscale Interactions during Substorms) began a careful study of the Earth’s magnetosphere. This cocoon invisible around the Earth is constantly struck days later by an intense flux of particles ejected by the Sun, the solar wind. (more…)

Located at the northern tip of Norway – the most northern European countries – is the aptly named North Cape, which is deemed as a privileged site for observing the aurora borealis. The only land located between North Cape and the North Pole are the Svalbard islands (in the upper left corner). Called in French Spitsbergen, Svalbard is an archipelago in the Arctic Ocean north of mainland Europe. It has been established by one of the tracking stations of the ESA, (more…)

Clouds of our atmosphere manufactured… by the cosmic rays

Posted on 17. Dec, 2009 by in Atmospheric Sciences, Earth Sciences, Featured

scince3By striking the water molecules suspended in the air, the cosmic rays would support the condensation of the water drops and thus the formation of the clouds. The assumption, already put forth, has just received a pretty confirmation thanks to the weather files. Side effect: the solar storms drain the atmosphere… What becomes the powerful cosmic rays, this flood of particles at relativistic speeds, composed with the nine tenth of protons, (more…)

Reversed flashes, which climb towards the sky

Posted on 17. Dec, 2009 by in Atmospheric Sciences, Earth Sciences, Featured

scinceCurious phenomenon, known recently and badly explained, the ascending flashes leave the top of the clouds of storm in direction of the ionosphere. By chance, an American team could photograph one of them and measure the electric charge of it. Usually, at the time of a storm, the flashes streak the sky between the base of the large clouds of storm, the cumulonimbus, and the ground. Thus the men saw them until the twentieth century. But it of different, is sometimes raised much of it, which is born with the top from these large clouds and slips by to the top, until reaching the (more…)

120 countries gathered for a global crisis

globe1Today, one billion people short of water. In 2030, the shortage will affect half of humanity. On this finding has started in Istanbul on Fifth Global Forum on Water. For one week, 30,000 people from around the world, including 15,000 researchers and policy makers, 180 ministers and 25 heads of state will discuss a critical issue for decades to come. The Fifth Global Forum on Water, held every three years by the World Council of Water (World Water Council), has just opened in Istanbul, Turkey, ending March 22. The Secretary-General United Nations, Ban Ki-moon, said that water scarcity “may fuel wars and conflicts.” (more…)

Earth seen from space: Aral, ice and salt

med_tehn3_13This image taken by Envisat shows the Aral Sea taken by the ice, which straddles the border between Kazakhstan and Uzbekistan in Central Asia. In fact the sea, it is rather a large salt lake. Once the fourth largest lake in the world, the Aral Sea has shrunk steadily over the past five decades. In the 1960s, Soviet planners diverted the waters of the two main rivers feeding the sea – the Amu Darya (visible to the south) and the Syr Darya (northeast) – to irrigate cotton plantations the region.

warming are grossly under-estimated

med_tehn3_12The integration of economic factors influencing the ongoing climate warming shows that without a rapid and massive, the situation may be at least twice as bad as expected. A new study spearheaded by a research team from Massachusetts Institute of Technology (MIT), headed by Professor Ronald Prinn, incorporates for the first time a wide range of data and economic forecasts from the Joint Program on the Science and Policy of Global Exchange, which coordinates the capabilities of two research centers at MIT: the Center for Global Change Science (CGCS) and the Center for Energy and Environmental Policy Research (CEEPR).
