Using crisp images and lifelike animations, this program introduces students to the intriguing realm of stars and galaxies. The main characteristics of galaxies and stars are discussed. Special attention is given to the features of stars, including size, temperature, and brightness. The life cycle of a star is also highlighted, as are the tools used by astronomers to study space. Additional concepts and terminology illustrated in the video include: universe, telescope, satellites, constellations, star color, spectrum, gas, light-year, and black hole.

Scientists learn the basic properties of stars by analyzing the light they emit. Clarifies how brightness and luminosity are determined, discusses stellar parallax, and explains star color and characteristics. Focuses on yellow, blue, and red stars, white dwarfs, red giants, black holes, and supernovae.
What are stars, and where do they come from? Briefly discusses the life cycle of a star, their colors, and super nova. Includes the Hubble Space Telescope, how stars were used in history, and constellations. Offers a short review.
Explains the names and functions of different parts of the human eye. Shows how the eyes and brain work together to see color and light. Tells how tears help keep eyes clean and healthy. Describes ways that a person's age affects their sight.
Professor Lawrence Gilbert and his team at the University of Texas at Austin have discovered a population of tropical butterflies that exemplify "evolution in action," and a rare research opportunity. Gilbert says they may be witnessing a species of butterfly splitting into two different species. The stars of this research are the Heliconius butterflies, found in Central and South America. Despite the genetic similarities between the two groups of the butterflies, one group is showing a color preference during mating. With support from the National Science Foundation, Gilbert and his team are working to gain insights about genetics, behavior, ecology, and evolution.
Cassini's sleuthing revealed an active ocean world. The spacecraft found evidence of geysers coming out of the south pole of Enceladus. After over a decade of research, NASA scientists know there is a potential for the ocean on Enceladus to support life, and that has altered the way scientists think about where life might be found in the solar system and in the worlds beyond.
The science of sight has entered a new era. Scientists are starting to understand how a few rare individuals can see better or see faster. Meet a woman who can see a hundred more colors than the average human being, and a heavyweight boxer who undergoes sophisticated training to increase the speed of his visual reflexes and acuity. As silicon and carbon meld and point the way to a bionic future, researchers discuss how technology is starting to replace or enhance vision for those who have lost it. Viewers witness the moment when a husband and father, equipped with an experimental retinal implant, sees his wife and child for the first time. Part of the “Human + The Future of Our Senses” series.
Part of a series that features a wide variety of video footage, photographs, diagrams and colorful, animated graphics and labels. Begins with a simple definition of the term and concludes with a critical thinking question. For this particular video, students will focus on the term physics. Part of the Science Video Vocab Series.

It is Fletcher's first autumn, and he is alarmed when the leaves on his favorite tree start to turn brown and fall off. He tries day after day to save the leaves that the tree is losing to the wind. When the tree has no leaves left, Fletcher goes to bed in despair. However, after a cold night, Fletcher wakes up to see his tree sparkling as he has never seen it before. Based on the children's book by Julia Rawlinson.
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.
Since the last ice age, plants in the Alaskan Arctic have been taking carbon out of the atmosphere and locking it away in the soil. But now, the permafrost is starting to thaw. That means all those microbes are about to find themselves at an all-you-can-eat carbon buffet. With support from the National Science Foundation, ecologist Matthew Wallenstein and a team from Colorado State University have come to the Toolik Field Station, deep inside the Arctic Circle, to drill soil cores for study. The researchers are trying to find out more about how microbes in the soil are cycling carbon from the Earth to the atmosphere. Part of the National Science Foundation Series “Science Nation.”
Defining color is a complex process that has consumed artists and scientists for many years. Takes a new approach to the understanding of color, providing a comprehensive overview of what it is, along with very clear, detailed explanations. Three-dimensional graphics help enable full understanding of all the dimensions of color and how it relates to creative visual arts.
An elementary class prepares for a visit from the Shadow Players, a group who use light, shadow, and color to tell a story. The class learns about sources of light, shadows, and silhouettes. They experiment with transparent, opaque, and translucent objects to see what lets light through. Using a prism, they discover the colors in light. Review at the end.
The Magic School Bus is an award winning animated children’s television series based on the book series of the same title by Joanna Cole and Bruce Degen. It is notable for its use of celebrity talent and being both highly entertaining and educational. When the kids see Horace Scope on the Star Shopping Network, they decide to buy Dorothy Ann a real twinkling star for her birthday. Before buying it, the kids blast off in the Bus to inspect the merchandise. They visit a young star, and then a middle-aged star, and then an old star. They decide to buy the old star. But when they give Horace their money, the star explodes. Have they lost D.A.'s star forever?
Discover how scientists compare the reflected red, blue, and green light from planets in the solar system to identify distant planets. Carolyn Crow, an astronomer, describes how the amount of green, blue, and red light reflected by planets can be plotted. A diagram compares the color data of the planets and shows that Earth is easily distinguishable by its blue color.
Nate explores the "Chemistry of Color" exhibit at the Indianapolis Museum of Art to find out more about color and pigments. The exhibit charts the relationship between chemistry and art over a period of more than 4,500 years. Part of the "Artrageous With Nate" series.
In this episode, scientists discuss the W5 star-forming region. Through the use of infrared light, they show areas within the region where new stars are being formed. Part of the "Ask an Astronomer" series.
Host Alex Dainis explains why leaves change colors during the fall. She examines the different colors of leaf pigments by using chromatography. In this experiment, viewers are able to see the various colors of pigments found in leaves.
