'Cosmos' Visits Venus to Talk Climate Change Sunday Night

SPACE.com

The Spaceship of the Imagination is headed for the hot and hellish landscape of Venus.

This Sunday night (June 1), the Fox TV series "Cosmos: A Spacetime Odyssey" will send viewers to Earth's evil twin to learn about the greenhouse effect and climate change.

Venus' dense atmosphere is mostly made up of carbon dioxide, with small doses of nitrogen and sulfuric acid. This composition creates a runaway greenhouse effect that bakes Venus to even hotter temperatures than the surface of Mercury, the planet closest to the sun.

The second-to-last episode of the series, titled "The World Set Free," will also explore the effects of global warming and humanity's impact on the Earth's atmosphere — and what people can do to mitigate the damage.

The 13-episode "Cosmos: A Spacetime Odyssey" is a reboot of the classic minisereis "Cosmos: A Personal Voyage," which was hosted by the famed astronomer Carl Sagan and first aired on PBS in 1980. The new series debuted on March 9 and is hosted by astrophysicist Neil deGrasse Tyson and written by Steven Soter and Ann Druyan, Sagan's widow. 

Sagan, who died in 1996, had a special connection with Venus: He was the first to create the greenhouse model for Venus' atmosphere, showing that the planet had much higher temperatures than previously suspected.

"Cosmos: A Spacetime Odyssey" airs Sundays at 9 p.m. ET/PT on Fox. It is rebroadcast on the National Geographic Channel on Mondays at 10 p.m. ET/PT. Check local listings.
