Endorian Extinction.

"What happens when you detonate a spherical metal honeycomb over five hundred miles wide just above the atmosphere of a habitable world?

Also found last night while perusing Star Wars sites, this technical commentary delves into the unwitting and horrifying environmental disaster precipitated by the Rebel Alliance upon the forest moon of Endor, as a result of the events depicted in Return of the Jedi (Another SW movie, as it turns out, that I went in massively spoiled for -- I was living in Belgium at the time, and it didn't open there until well after the US release.)
