It’s a golden age for planet hunters: NASA's Kepler mission has identified more than 3,500 potential planets orbiting stars beyond our Sun. Some of them, like a planet called Kepler-22b, might even be able to harbor life. How did we come upon this distant planet? Combining startling animation with input from expert astrophysicists and astrobiologists, “Alien Planets Revealed” takes viewers on a journey along with the Kepler telescope. How does the telescope look for planets? How many of these planets are like our Earth? Will any of these planets be suitable for life as we know it? Bringing the creative power of veteran animators together with the latest discoveries in planet-hunting, “Alien Planets Revealed” shows the successes of the Kepler mission, taking us to planets beyond our solar system and providing a glimpse of creatures we might one day encounter.

Active galaxies pour out lots of energy, due to their central supermassive black holes gobbling down matter. Galaxies tend not to be loners, but instead exist in smaller groups and larger clusters. Our Milky Way is part of the Local Group, and will one day collide with the Andromeda galaxy. Clusters of galaxies also clump together to form superclusters, the largest structures in the Universe. In total, there are hundreds of billions of galaxies in the Universe.

More than three decades after the debut of Carl Sagan's ground-breaking and iconic series, "Cosmos: A Personal Voyage," it's time once again to set sail for the stars. Host and astrophysicist Neil deGrasse Tyson sets off on the Ship of the Imagination to discover Earth's Cosmic Address and its coordinates in space and time. Viewers meet Renaissance Italy's Giordano Bruno, who had an epiphany about the infinite expanse of the universe. Then, Tyson walks across the Cosmic Calendar, on which all of time has been compressed into a year-at-a-glance calendar, from the Big Bang to the moment humans first make their appearance on the planet.
