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.

Look up at the night sky, and you see countless shining stars. Our galaxy has 100 billion of them. Astronomers are now hunting for clues that will reveal "the first star" that transformed the ancient universe and led to the creation of everything that followed: galaxies, planets and life itself.

This visually stunning program chronicles a sweeping journey, from 1609 when Galileo revealed mankind's place in the galaxy to 2009, the International Year of Astronomy. Narrated by NOVA's Neil deGrasse Tyson, the compelling program takes viewers on an adventure through the heavens and around the globe, visiting the world's leading astronomers, cosmologists and observatories. The Interstellar Studios production team traveled the globe to interview leading astronomers and cosmologists from the world's renowned universities and observatories. The producers sought the most acute minds at great astronomical centers including the European Southern Observatory, Institute for Astronomy, SETI Institute, Space Telescope Science Institute, Anglo-Australian Observatory, and Harvard University. They journeyed across five continents to visually write the story of the past and the future of telescopes, astronomy, and our ever-changing perception of the cosmos. Compelling interviews throughout the film leave no stone unturned. A carefully chosen array of today's leading astronomers explain concepts ranging from Galileo's act of revealing the telescopic cosmos to humanity and challenging religious teachings of the day, to the latest discoveries in space, including startling new ideas about life on other planets and dark energy – a mysterious vacuum energy that is accelerating the expansion of the universe. On the horizon, viewers learn of emergent telescopes the size of stadiums. With unprecedented resolution and light gathering, these enormous new instruments will look back to the initial moments of the Big Bang and – like Galileo's first telescopic observations – will reshape our model of the universe.

NASA may have just gotten one step closer to the answering the question: are we alone? The Spitzer Telescope has made a groundbreaking discovery of exoplanets that could be similar to our own. And as Kepler also continues its search, our understanding of the universe continues to be redefined.
