Part adventure, part history lesson, and part treasure hunt, eight-time Emmy® Award-nominated ANTIQUES ROADSHOW marks its 15th season in 2010. PBS's highest-rated series, ROADSHOW is seen by almost 10 million viewers each week. Veteran television personality Mark L. Walberg serves as series host. In each hour-long ROADSHOW episode, specialists from the country's leading auction houses—Bonhams and Butterfields, Christie's, Doyle New York, Skinner and Sotheby's—and independent dealers from across the nation offer free appraisals of antiques and collectibles. ANTIQUES ROADSHOW cameras capture tales of family heirlooms, yard sale bargains and long-lost items salvaged from attics and basements, while experts reveal the fascinating truths about these finds.

Through interviews with top prosecutors, government officials and industry whistleblowers, FRONTLINE reports allegations that Wall Street bankers ignored pervasive fraud when buying pools of mortgage loans. Tom Leonard, a supervisor who examined the quality of loans for major investment banks like Bear Stearns, said bankers instructed him to disregard clear evidence of fraud.

It contains 99.9 percent of all the matter in our solar system and sheds hot plasma at nearly a million miles an hour. The temperature at its core is a staggering 27 million degrees Fahrenheit. It convulses, it blazes, it sings. You know it as the sun. Scientists know it as one of the most amazing physics laboratories in the universe. Now, with the help of new spacecraft and Earth-based telescopes, scientists are seeing the sun as they never have before and even recreating what happens at its very center in labs here on Earth. Their work will help us understand aspects of the sun that have puzzled scientists for decades. But more critically, it may help us predict and track solar storms that have the power to zap our power grid, shut down telecommunications, and ground global air travel for days, weeks, or even longer. Such storms have happened before—but never in the modern era of satellite communication. "Secrets of the Sun" reveals a bright new dawn in our understanding of our nearest star—one that might help keep our planet from going dark.
