Forum:Solemn judgement vs stardust dragon

i know this question has probably been asked before BUT : solemn judgement vs stardust dragon,  does solemn judgement beat star does because it's a faster spell speed? or the "Negate the activation" part ? example : player one has stardust on the field, play two has solemn set , player 1 activates lightning vortex (for example) , player 2 activates solemn. can star dust negate solemn? because it says destroy the Spell Card?
