Documents efforts to contact and communicate with potential extraterrestrial life and interstellar space. Attempts to answer the question: Are we alone? Looks at the Drake equation, the standard for anyone seeking to find the number of planets with intelligent life in the Milky Way galaxy. Discusses the pioneering research at the Search for Extraterrestrial Intelligence Institute (SETI) based in Mountain View, California.

Examines the science of travelling beyond our solar system with the latest developments from NASA. Looks at what technology and research steps are being taken that might enable us someday to go visit other planets. Reports on the Phoenix Lights, the most recent mass UFO sighting, as presented through witness accounts. Also includes commentary from skeptical analysts to represent both sides in this highly debated topic.
Provides insights on extraterrestrial life from scholars and astronomers at premier research institutions, such as the Harvard-Smithsonian Center for Astrophysics and NASA. Shows how proponents of the "aliens are here" theories have compiled a library of books, Internet sites, and documentaries to support their ideas. Includes an interview with Budd Hopkins, author of several alien abduction books, and a hypnosis session of a young man who recalls encountering alien creatures. Also includes a demonstration by an illusionist who shows that hypnosis is nothing more than tricking the mind.
A ball flying through the air, a deer walking in the woods, and a flowing river - these are all examples of moving objects. Students explore the characteristics of things in motion, and special attention is given to the forces that initiate and change their movement. Concepts and terminology discussed include: motion, push, pull, force, direction, and speed.
The concept of propulsive thrust to move objects over large distances is ancient. Yet, the technology to move an automobile forward or a rocket into space was invented less than two centuries ago. The invention of the solid fuel propulsion system combined with Newton's Third Law is the simplistic basis for modern rocketry. Students will review the history of propulsion and explore its use as a viable energy source of the future.
Harvard University, electrical engineers Rob Wood and Gu-Yeon Wei, and computer scientist Radhika Nagpal created the “RoboBee,” a miniature flying robot, inspired by the biology of a bee and the insect’s hive behavior. With support from the National Science Foundation and a program called Expeditions in Computing, Wood put together a diverse team of collaborators to get the RoboBee project off the ground. Ultimately, the researchers hope to build a colony in which the RoboBees interact, using their hive as a refueling station. They say RoboBees have the potential to be useful in a number of ways, including search and rescue missions, traffic monitoring, and weather mapping. Part of the National Science Foundation Series "Science Nation."
I think what your eyesight does is confirm other senses, says James Robertshaw, a world champion kite flyer and for two years personal assistant to Rory Heap. Heap has been blind from birth, but with Robertshaw's assistance pursues his ambition for kite flying--particularly of complicated figure eight patterns. Using all of his senses except for sight, Heap learns how to fly a kite with the same dexterity that Robertshaw uses to guide him through busy city streets.
In each episode, viewers are given clues about a hidden animal inside a magic box. Can viewers use all the clues to correctly name this fish that likes to propel itself out of water at speeds of more than 35 miles an hour? Part of the "Zoobabu" series.
NASA’s "Juno" spacecraft traveled 1.7 billion miles to reach its destination: the planet Jupiter. Before "Juno’s" journey, NASA engineers had to develop a spacecraft capable of surviving the trip. They researched and created "Juno," a solar-powered spacecraft. Part of the “Crazy Engineering” series.
An orphanage for injured animals in northeastern Australia raises 500 baby spectacled flying foxes each year. The youngsters have lost their mothers to a disease caused by ticks. The adult flying foxes suffer paralysis when bitten by ticks, and workers from the animal orphanage care for the babies hoping to release them back into the wild. Segment of video from Wild Chronicles Series.
Dr. Chris is called to help at the local bat hospital. Can Dr. Chris save a bat named Millie who is covered in goo? He must also help a currawong with a wooden skewer through its wing. At SASH, Dr. Lisa diagnoses a listless puppy named Jelly. Part of the "Dr. Chris Pet Vet" series.
Stacey Combes, a biomechanist at Harvard University, and her team are using high speed cameras to help them study how dragonflies pull off complicated aerial feats that include hunting and mating in mid-air. They can fly straight up, straight down, hover like helicopters and disappear in a blur. Combes is also exploring the use of dragonflies for mosquito control.
Real satellite imagery, as well as simulations, explore how Earth's moon has changed over time. This video looks at how the moon likely formed about 4.5 billion years ago, how impacts from large objects formed craters, and how additional impacts from smaller objects continue to cause cratering.
A small prairie town has few secrets but in Balgonie, Saskatchewan, William (Bill) Wallace Gibson had one. Each night, when most folks were home asleep, Bill was busy in his workshop. Bill had a dream. He was building a flying machine. This short puppet animation tells his story.
In this behind-the-scenes glimpse into the skeletal collections at The Field Museum, host Emily Graslie examines various elephant skeletons. Bill Stanley, Director of the Gantz Family Collections Center, describes the differences in skull structure between the species. Part of "The Brain Scoop" series.
Magnets can be found in many objects used everyday. Not only are they located in man-made objects, but magnetic materials can be found in nature as well. Students will gain general information about magnetism, as well as concepts about atoms and the relationship between electricity and magnets. Part of the Real World Science series.
On the windswept tarmac of the former Alameda Naval Air Station, an inventive group of scientists and engineers are test-flying a kite-like tethered wing that may someday help revolutionize clean energy. Students explore the potential of wind energy and new airborne wind turbines designed to harness the stronger and more consistent winds found at higher altitudes.
Provides an overview of how Newton's three laws of motion can be used to explain and predict the motion of everyday objects. The effect of friction, including air resistance, is highlighted, and the concept of inertia is illustrated with classic demonstrations. Features questions for class discussion, as well as the remarkable Rocketman, who provides a dramatic example of the third law in action.
Part of the "Inside the Living Cell" series. Describes the properties of the plasma membrane, how it governs the kinds of molecules that go in and out of cells, and how cells feed by engulfing (phagocytosis) and drinking in (pinocytosis) fluids. Also reviews membrane structure, osmosis, transport proteins, active transport, cell eating, cell drinking, and receptor proteins.
Gabriela, Manuel and Leonardo are three friends who accidentally start a rocket that takes them to space. Their journey through space takes them to different planets and strange worlds. Throughout their journey, they have the help of Maqui, an on-board computer. Maqui helps them learn about the universe. The spaceship lands on a planet where a robot is expecting them. His only interest is in Maqui. The robot shows her around the planet and reveals some of the planet’s objects. He shows her ships, satellites, and other space objects that were launched from planet Earth.
