Significant total solar eclipse of century on July 22
According to astronomers and research scientist, the most significant total solar eclipse of the century is falling on Wednesday July 22, 2009. Scientists and astronomers around the world are preparing to study the solar eclipse specially the study of shadow bands. Shadow bands are thin wavy lines of alternating light and dark that can be seen moving and undulating in parallel on plain-coloured surfaces immediately before and after a total solar eclipse. However, a new theory has been put forward by Dr. Stuart Eves, who works for Surrey Satellite Technology Limited (SSTL), that shadow bands might actually be caused by infrasound, which involves the shadow of the moon travelling at supersonic speed which in turn produces high frequency sound that humans can't hear and because of this, creates a shockwave in front of the shadow, which causes shadow bands. 'Maitri' the Indian astronomy station at Antarctica got the first chance to study shadaow bands for the first time on Nov...
