NOVA
Petra: Lost City of Stone

 

More than 2,000 years ago, the thriving city of Petra rose up in the bone-dry desert of what is now Jordan. An oasis of culture and abundance, the city was built by wealthy merchants who carved spectacular temple-tombs into its cliffs, raised a monumental Great Temple and devised an ingenious system that channeled water to vineyards, bathhouses, fountains and pools. But following a catastrophic earthquake and a slump in its desert trade routes, Petra’s unique culture faded and was lost to most of the world for nearly 1,000 years. Now, in a daring experiment, an archaeologist and several sculptors team up to carve an iconic temple-tomb to find out how the ancient people of Petra built their city of stone.

Yosemite

 

Yosemite Valley is a land forged in wildfire and sculpted by water, and the delicate balance of these two elements is essential to the creatures and trees that call this land their home. But with climates changing and temperatures rising, the Sierras are under siege. Water is scarcer and the threat of fire is more common. Join scientists and adventurers as they trudge through mountains of snow, climb trees as tall as buildings and soar high in the air to spy just how these global changes are affecting one of America’s greatest wildernesses.

NOVA
Invisible Universe Revealed

 

Twenty-five years ago, NASA launched one of the most ambitious experiments in the history of astronomy: the Hubble Space Telescope. In honor of Hubble’s landmark anniversary, NOVA tells the remarkable story of the telescope that forever changed our understanding of the cosmos and our place in it. From its inception through its early days, when a one-millimeter engineering blunder turned the telescope into an object of ridicule, to the five heroic astronaut missions that returned Hubble to the cutting edge of science, NOVA hears from the scientists and engineers on the front line who tell the amazing Hubble story as never before. This single telescope has helped astronomers pinpoint the age of the universe, revealed the birthplace of stars and planets, advanced our understanding of dark energy and cosmic expansion and uncovered black holes lurking at the hearts of galaxies. For more than a generation, Hubble’s stunning images have brought the beauty of the heavens to millions, revealing a cosmos richer and more wondrous than we ever imagined. Join NOVA for the story of this magnificent machine and its astonishing discoveries.
