Actors are seen in a spaceship searching for habitable zone exoplanets.

A new episode of "The Habitable Zone" follows Cas Anvar and Cara Gee (“The Expanse”) starring as explorers and entering a planetary danger zone in their quest for another Earth. Can their computer (Parry Shen of “General Hospital”) save them from a nasty fate? This video series is the latest installment in the "Universe Unplugged" astronomy-themed video series.

What can turn a seemingly perfect ocean-rich planet into an uninhabitable desert wasteland? Two future space explorers (played by Cas Anvar and Cara Gee of “The Expanse”) aim to find out in "Scorched Earth Enigma," a science-grounded sci-fi video from NASA’s Universe of Learning project. While the story is a work of fiction, the ideas are pulled directly from current exoplanet science and vetted by astronomers and education specialists.

Space explorers Cas Anvar and Cara Gee (“The Expanse”) are searching for a new hospitable world, aided by their computer with a Rod Serling complex (Parry Shen of “General Hospital”).

This video appropriately comes at a time when NASA looks back at the 50th anniversary of the Apollo 11 Moon landing, and forward to our return to the Moon, an important step in sending humans to Mars. Inspired by this commitment to science and exploration, “The Habitable Zone: Scorched Earth Enigma” lets us imagine what future astronauts might face if we someday move beyond the Moon and Mars to visit worlds beyond our solar system (exoplanets).

To date, scientists have discovered over 4,000 exoplanets in our galaxy, with more being found every month. The question naturally arises: Is life possible on any of them?

This is the central theme of “The Habitable Zone” video series, in which each episode examines a different science consideration of conditions necessary to make an exoplanet hospitable to life, particularly humans. The name of the series is the same term used by astronomers to describe the region around stars in which an Earth-like planet could potentially support liquid water on its surface.

A good supply of liquid water would be a key step to nurturing life (at least as we know it) on an exoplanet.

The new episode (“Scorched Earth Enigma”), co-starring Parry Shen (“General Hospital”), examines how the activity of a host star could have devastating impacts on the atmospheres and oceans of their orbiting worlds. It continues the story of “Goldilocks Paradox,” the first episode in the series (released late 2018), where the explorers learned that both a planet’s composition and location are critical in determining whether it could be covered in liquid water.

The visuals for the series are created by the same science visualization team that has helped to illustrate some of NASA’s most significant astrophysics and exoplanet discoveries from missions like the Kepler and Spitzer space telescopes.
