Europe's Euclid space telescope launched on mission to explore 'dark universe'

A European-built orbital satellite was launched to space on Saturday from Florida on a mission to shed new light on the mysterious cosmic phenomena known as dark energy and dark matter, unseen forces scientists say account for 95% of the known universe. The telescope dubbed Euclid, named for the ancient Greek mathematician called the "father of geometry," was carried aloft in the cargo bay of a SpaceX Falcon 9 rocket that blasted off around 11 a.m. EDT (1500 GMT) from Cape Canaveral Space Force Station.
