"How did NASA engineers build and launch the most ambitious telescope of all time? Follow the dramatic story of the James Webb Space Telescope -- the most complex machine ever launched into space. If it works, scientists believe that this new eye on the universe will peer deeper back in time and space than ever before to the birth of galaxies, and may even be able to "sniff" the atmospheres of exoplanets as we search for signs of life beyond Earth....

"When Mount St. Helens erupted in 1980, every living thing in the blast zone was buried. However, life began to bloom again, and biologist Charlie Crisafulli has been documenting the return of plant and animal life. Also the mountain, like the wildlife, is coming back to life. Nova presents a pioneering look at the interplay between biology and geology that may help scientists predict future volcanic eruptions"--Publisher.

The source of the earth's great variety of animals was a scientific mystery until Charles Darwin proposed the idea of natural selection. Nova presents breakthroughs in a new science nicknamed "evo devo" that are linking the enigma of origins to another of nature's mysteries, the development of embryos.

A NASA spacecraft named Lucy blasts off from Cape Canaveral on a mission to the Trojans, a group of asteroids over 400 million miles from Earth thought to hold important clues about the origins of our solar system. Just hours before, in Senegal, West Africa, a team of scientists sets out to capture extraordinarily precise observations vital to the success of the Lucy mission crucial data needed to help NASA navigate Lucy to its asteroid targets across...

One of the world's greatest ancient enigmas, the Nazca lines are a dense network of criss-crossing lines, geometric shapes, and animal figures etched across 200 square miles of Peruvian desert. Who created them and why?

Travel back in time, from the Arctic Ocean to Pacific tide pools, with a pioneering group of scientists who make surprising discoveries that transform human understanding of nature and ecology.

Step behind the headlines as Making Stuff dramatizes the human stories woven into the current wave of hi-tech breakthroughs. Hosted by the New York Times' lively technology correspondent David Pogue, each hour in this four-part series explores the talent, luck, and determination that can turn a wild idea into a cutting-edge material or high-tech breakthrough.

Every year, a million visitors are drawn to the Salisbury Plain in southern England, to gaze upon a mysterious circle of stones. Stonehenge may be the best-known and most mysterious relic of prehistory. Now investigations inside and around Stonehenge have kicked off a dramatic new era of discovery and debate. Who built Stonehenge? What was its purpose? How did prehistoric people quarry, transport, sculpt, and erect the giant stones? A new generation...

For 30 years, scientists have been on the hunt for the source of the most powerful and mysterious explosions in the universe.
