The Atacama Large Millimeter/Submillimeter Array, or ALMA, is already producing amazing science results. To see the telescope up close at an altitude of 16,500 feet (5,000 meters) is even more incredible. This high-precision instrument on top of the world is truly one of the most impressive sights that I have ever seen.
So what’s the big deal with a “millimeter and submillimeter” telescope anyway?
