Our middle-aged sun has fascinated people throughout history, but only since the rocket age have scientists been able to document its life and the forces that sustain it. Explores sunspots, solar cycles, the birth of a solar storm, and the use of specialized spacecraft outside earth's ionosphere.

Our Sun is a nuclear reactor converting hydrogen to helium continuously. X-ray and telescopic images reveal the Sun's photosphere and chromosphere, sun spots, solar flares and winds, and prominences. Describes each and its impact on Earth. Covers some of the Sun's mysteries, and projects what will eventually happen to our closest star.
Moko is an explorer. As he travels the world continent by continent, he makes many friends and discovers many natural phenomena which sometimes delight him, and other times scare him. Each animated episode recounts an adventure and takes an "original story" approach to explaining these natural phenomena. In this episode, in the middle of the day, the sun gradually vanishes. Moko is frightened and wonders what wizard could do such a thing. With the village wise man, they set out to find the sorcerer who made the sun disappear. They question all the sorcerers they know but fail to find the one responsible for such an act. So they decide to join all the people of their village and the neighboring villages and watch the sky. An old woman watches them, smiling. She explains that when she was a child the same thing happened, but that the world would become normal again. And indeed the sun returned at the end of the solar eclipse. Moko told himself that perhaps the sun was simply tired and for once decided to go off and take a nap.
Moko is an explorer. As he travels the world continent by continent, he makes many friends and discovers many natural phenomena which sometimes delight him, and other times scare him. Each animated episode recounts an adventure and takes an "original story" approach to explaining these natural phenomena. In this episode, Alarick's country is very strange. It has been many days now that night has not fallen, and no one seems to be worried. Moko decides to head towards the horizon to see what is keeping the sun from setting and Alarick goes with him. Along the way, Moko tries to lull the sun to sleep with a lullaby from his country. The sun looks like it will set, but stops short and rises again. Perhaps the ocean is frozen at the horizon and is keeping the sun from setting. He decides to ask the fishermen and one of them responds that the world is filled with such mysteries and that it is more precious for him to learn the secrets of his friend than that of the sun.
Through telescopic video and photos combined with animated graphics, students will learn about the layers of the sun, and its effects on earth, the moon, and other objects in the solar system. Part of the Real World Science series.
Students investigate properties of the Sun. Special attention is given to other celestial bodies in space such as asteroids and comets.
This program from the acclaimed PBS Nature series, "Forces of the Wild," focuses on how the movements of the sun and moon create powerful rhythms which influence all living things on Earth: tides rise and fall, seasons change, creatures breed or migrate, and humans plant crops and celebrate holidays. Narrated by James Earl Jones.
The sun's powerful, warm rays light up the sky with brilliant color and heat. The changing cycles of the sun can affect the earth and its living organisms. The sun is similar to a living organism-just as humans are born, grow older, and die, so too will the sun. When this happens, the rest of the solar system will have no future.
Looks at the hazards that may be encountered during a trip to the beach, both in and out of the water, and demonstrates ways to prevent or avoid them. Provides information on hypothermia, riptides, marine life, and sunburns. Also covers boardwalk injuries, board surfing accidents, and ocean pollution. Includes question-and-answer segments with beachgoers, incident reenactments, and interviews with veteran lifeguards of Newport Beach, California.
Students take a scientific look at some of the important characteristics of the earth, moon, and sun. Differences and likenesses between earth, moon, and sun are discussed as well as how scientists explore these bodies. The main phases of the moon are addressed, as is the formation of tides. Terminology includes: gravity, atmosphere, lunar phase, tides, eclipse, high tide, and low tide.
How does the Earth travel around the sun? Here the scientists will create a sundial to find out. The scientists will also explain how a remote control works. Part of the House of Science Series.
About every two years, Earth and Mars wind up on opposite sides of the sun, which can block the signals sent by the rover. During this solar conjunction, scientists must ensure they do not lose any of the data being sent by “Curiosity.” Part of the “Mars in a Minute” series.
Bill Nye sheds some light on the similarities and differences between Jupiter and the sun. Part of the “Why With Nye” series.
It is a fireball in the sky, a bubbling, boiling, kinetic sphere of white hot plasma, exploding and erupting. Its size is almost unimaginable--one million Earths would fit within its boundaries. In this violence is born almost all the energy that makes existence on Earth possible. Yet, its full mysteries are only now beginning to be understood. From sunspots to solar eclipses, solar flares to solar storms, the birth of the sun to its potential death, discover the science and history behind this celestial object that makes life on Earth exist.
Sunspots have fascinated sky gazers through the ages. Now state-of-the art telescopes combined with the muscle of a supercomputer called “Bluefire” are allowing scientists to accurately model these mysterious structures, and unlock their secrets. Michael Knoelker and Matthias Rempel are solar scientists working at the High Altitude Observatory at the National Center for Atmospheric Research, known as NCAR, in Boulder, Colorado. With support from the National Science Foundation, their study of sunspots is critical to the understanding of how stars, like the sun, produce magnetic fields which is still one of the big unanswered questions in stellar astrophysics.
Conservation efforts benefit everyone, and this episode explores the various efforts to protect the monarch butterfly. Today, the governments of Canada, Mexico, and the United States maintain a common political project in favor of the conservation of these insects. Part of the "Bios: Nature and Society" series.
Dr. Carolyn Brinkworth addresses a famous science fiction scenario in this episode. She discusses the three requirements for planets to form around binary stars. Part of the "Ask an Astronomer" series.
If the sun instantly switched off like a light bulb, it would take almost 8 and a half minutes before humans on Earth realized what happened. Light travels at the fastest speed there is, but it still takes almost 500 seconds to get to Earth. This means the sunlight that reaches Earth is old. How is that possible? It is due to the concept of random walks. Part of the “It’s Okay to Be Smart” series.
David Boboltz of the National Science Foundation explains the hazards of not wearing the appropriate glasses to view the solar eclipse on August 21, 2017. Those wishing to view the eclipse need to make sure they have approved solar glasses so they do not damage their eyes.
The planets closest to the sun, often referred to as the inner planets, are the focus of this program. Colorful animations, along with images captured by space probes, illustrate the characteristics of Mercury, Venus, Earth, and Mars. The fundamental structure of the solar system and the process by which planets revolve around the sun are discussed. Special attention is given to the features that make Earth unique in the solar system. Important terminology includes: sun, orbit, revolve, gravity, inertia, rotation, axis, atmosphere, and spacecraft.
