Everyone knows that eight planets orbit the Sun. But thousands of other objects, including icy comets and football field-sized asteroids, are also zooming around our solar system. And some of them could be on a collision course with Earth. QUEST explores how these Near Earth Objects are being tracked and what scientists are saying should be done to prevent a deadly impact.

The Hindenburg wasn't the only air ship to end in a catastrophic crash. In 1935, the USS Macon went down in 1000 feet of water off the coast of Monterey, California. Now, as scientists study the recently-discovered wreckage, dirigibles are returning to the Bay Area and are poised to rule the skies once again. But these aren’t the same dirigibles - these are new and improved.

Photographer Laura Watt has lived in the Bay Area for most of her life but it was not until she started sailing in San Francisco Bay at age 35 that she began to appreciate the patterns, textures and colors of the precious water that surrounds us all. Self-described as "trawler trash," she lives aboard her boat in San Rafael's Loch Lomand Marina, granting her a front row seat to the dynamic body of water that she captures so well in her moody, intimate images.

As the Bay Area has become more urban, many wild animals have disappeared. But not mountain lions. These large cats live surprisingly close to us, and yet they're not as dangerous as many believe. Now, researchers in the mountains north of Santa Cruz are using new technology to learn more about these elusive animals.

Melting glaciers, rising temperatures and droughts - all are impacts of global warming. What receives much less attention is the toll that climate change is taking on the health of our oceans. The sea, it turns out, absorbs carbon dioxide emissions, which are causing it to become more acidic. Changing pH levels threaten the entire marine food chain from coral reefs to salmon.

It's been 150 years since Charles Darwin published On the Origin of Species. Yet his ideas remain as central to scientific exploration as ever. QUEST follows researchers who are still unlocking the mysteries of evolution, like entomologist David Kavanaugh, who predicted that a new beetle species would be found on the Trinity Alps. Find out if his prediction came true...

If you're looking to buy an all-electric car you can drive on the freeway, your options are limited. $100,000 will buy you an electric sports car from Tesla. But an affordable all-electric vehicle remains elusive, due to the difficulty in making a battery that is powerful, long-lasting, and cheap. QUEST visits a local battery laboratory and investigates the odds of a breakthrough.

Solar and wind power may get the headlines when it comes to renewable energy. But another type of clean power is heating up in the hills just north of Sonoma wine country. Geothermal power uses heat from deep inside the Earth to generate electricity. The Geysers, the world's largest power-producing geothermal field, has been providing electricity for roughly 850,000 Northern California households, and is set to expand even further.
