After the entire flora goes extinct, ecologist Lowell maintains a greenhouse aboard a space station for the future with his android companions. However, he rebels after being ordered to destroy the greenhouse in favor of carrying cargo, a decision that puts him at odds with everyone but his mechanical companions.

In 1976, a drifting star named Gorath is discovered to be on a collision course with Earth. Although it is smaller than Earth, its enormous mass is enough to destroy the planet totally. A mission sent to observe Gorath is destroyed after the ship is drawn into the star, with a later mission barely escaping the same fate. However, Astronaut Tatsuma Kanai is left in a catatonic state due to his near death experience. Unable to destroy the invading star, Earth's scientists undertake a desperate plan to build giant rockets at the South Pole to move the planet out of Gorath's path before it is too late.

In the future Saturn's moon of Titan houses a prison where Earth's worst criminals are kept awaiting their return to Earth for trial and execution. One of those criminals, Python Diamond, is being flown back to Earth, escorted by five members of the military police. Upon their return to Earth, they find that a cataclysmic nuclear war has reduced the world to a near-lifeless husk. Searching for survivors and any clue as to the cause of the destruction leads the six to a warehouse bunker housing scientists who constitute Earth's last remaining hope for the future. Unfortunately, their landing spacecraft drew the attention of one of the gangs that roam the ruined countryside in search of food and resources, leading them straight to the carefully hidden and well-provisioned shelter. The gang lays siege to the warehouse, fighting their way inside in a bloody battle that takes lives on both sides.

After decades of amazing discoveries, spacecraft Cassini embarks on its final - and most daring - mission: a dive below Saturn's rings.

Planetary scientist Carolyn Porco explains what it takes to look for life beyond Earth, and what conditions are required for life to exist. Porco argues that Saturn’s moon Enceladus—with its plumes of water vapor spewing into space, confirmed organic materials, and evidence of hydrothermal vents at the bottom of its liquid ocean—is the most promising place to look. Could Enceladus be the key to proving once and for all that life is not unique to Earth? What would it mean—both scientifically and spiritually—if we found evidence of a true second genesis right here in our own galactic back yard?
