How Star Wars Trumped Star Trek For Scientific Accuracy

An anonymous reader writes "When George Lucas added the 'ring around the Death Star' effect to his 1997 re-release of Star Wars Episode IV: A New Hope, the revision was almost as hated as Greedo shooting first, and to boot was seen as a knock-off of the seminal 'Praxis effect' in Star Trek VI: The Undiscovered Country (1991). But a debunking astronomer claims that the Federation got it wrong and the fan-boys should thank Lucas for adding some scientific accuracy to his fictional universe."
