At sufficiently low frequencies, no ground-based radio array will be able to produce high resolution images while looking through the ionosphere. A space-based...
Space-qualified liquid-crystal variable retarders for wide-field-of-view coronagraphs
Liquid-crystal variable retarders (LCVRs) are an emergent technology for space-based polarimeters, following its success as polarization modulators in ground...
Astrophysics is a very recent development in Spain, but its spectacular evolution in itself constitutes a singular phenomenon that has aroused the interest of...
Spanish Monitoring of Comets: Making Sense of Amateur Photometric Data
Amateur astronomers have always represented an important observing group in cometary astronomy. Much of our knowledge of cometary light curves has come from...
