Atacama Large Millimeter/submillimeter Array
The Atacama Large Millimeter/submillimeter Array in the Atacama Desert, Chile, is the most complex observatory ever built.
Very Long Baseline Array
The Very Long Baseline Array (VLBA) is ten radio telescopes stationed across 5,351 miles. It’s the world’s sharpest, dedicated telescope array.

A Star, Sprinkled with SaltArtist impression of Orion Source I, a young, massive star about 1,500 light-years away. New ALMA observations detected a ring of salt -- sodium chloride, ordinary table salt -- surrounding the star. This is the first detection of salts of any kind associated with a young star. The blue region (about 1/3 the way out from the center of the disk) represents the region where ALMA detected the millimeter-wavelength "glow" from the salts.
