For the first time, NASA scientists were able to reconstruct an image of our star in three dimensions. Kiss the sun at a glance is now possible. Sunday, two twins named Stereo probes and weighing nearly 620 pounds each, have taken a position on either side of the star. Each shot half of the star and transmitted the images to NASA researchers, who, by combining both perspectives, have made the portrait of a 3D sphere of high temperature plasma of magnetic fields traversed complex . Fruit of a Euro-American cooperation, the mission will Stereo, including launch, cost about $ 550 million.
To achieve this feat, the two probes launched October 26, 2006 from Cape Canaveral were equipped with telescopes tuned (adjusted) at four wavelengths of extreme ultraviolet radiation to permit observation of the key aspects of solar activity such that magnetic flares or filaments. Valuable data which aims to better understand the activity of our star, only a global view of the Sun may allow the understanding of all magnetic phenomena that affect the crown of this star without whom life would not be possible on Earth.
