WebGALEX will conduct an all-sky imaging survey, a deep imaging survey, and a survey of 200 galaxies nearest to the Milky Way Galaxy. As well, GALEX will perform three spectroscopic surveys over the 135-300 nanometer band. GALEX has a planned 29 month mission, and is a part of the Small Explorers (SMEX) program. WebThis is accomplished by reflecting the light off a mirror with a sophisticated coating that cuts out visible light but refelcts the near-ultraviolet. The far-ultraviolet light is passed …

WebNov 7, 2011 · GALEX, which stands for “Galaxy Evolution Explorer,” is an ultraviolet space telescope with a special ability: It is super-sensitive to the kind of UV rays emitted by the youngest stars. This means the observatory can detect stars being born at very great distances from Earth, more than halfway across the Universe. WebWeighing 90 tons themselves, the transporters are powered by 380- and 400-horsepower (respectively) diesel engines that in turn power a hydraulic system. That system drives the wheels using radial hydraulic motors and also powers the jacks that lift the antennas off their concrete-pier mountings.
