On a high plateau in a remote desert in northern Chile lies the largest observatory on Earth, ALMA, or Atacama Large Millimeter/Submillimeter Array. The name refers to a network of 66 massive radio telescopes, working in unison to observe the birth and death of stars and planets, and answer centuries-old questions about the origins of our universe. Witness the history of ALMA, the remarkable product of a 20-year global effort, and see how it is already changing our basic understanding of the cosmos, and astronomy itself.
For twenty years, NASA's Cassini spacecraft revealed the strange secrets of Saturn until it vaporized in its atmosphere in a blaze of glory. But today its legacy lives on, as fresh data from the probe helps scientists make brand-new discoveries.
