Where do baby animals come from? What do they look like? A family visits a farm in spring and learns the answers. Shows a duckling hatch and a lamb and calf being born. Viewers decide which creatures are born from eggs and which are born live. Later that spring, the family has a new baby.

Astrophysicists at the American Museum of Natural History are searching through early photographs of the night sky in an effort to digitize the collection of photographs. Also in this episode, they discuss the advancement of astronomical instrumentation through the ages. Part of the "Shelf Life" series.
Depicts the different stages in the birth and death of stars, including the sun. There are 100 billion stars in the Milky Way galaxy alone, and there are 100 billion galaxies. Provides an overview of radiated energy, which is in all wavelengths; nuclear fusion; and fierce magnetic fields, which create all solar events. Explains that the length of a star's life and how it dies are determined by gravity and how gravity is proportional to size.
Shares a broad look at stars--their formation, life, and types of death. Mentions red giants, blue stars, supernovas, red dwarfs, black holes, and others. Notes that astronomers study a star's light to learn about it. Projects what will happen to our star, the sun.
Gravity rules the life cycle of stars. During the Red Giant dying stage in the life of an average size star, its outer layers are blown off in vast clouds of dust and gas called "nebulae" that contain hydrogen, oxygen, and nitrogen. Gravity crushes the remaining atoms into a remnant core called a white dwarf. The gravity of giant stars-10 to 20 times larger than average-will, at the end of their life in a supernova explosion, crush together even mutually repulsive protons and electrons, leaving a remnant rotating core of neutrons (i.e., a pulsar). Also explains how stars 20 to 100 times average size collapse into a core so dense that its gravity doesn't even allow light to escape (i.e., a black hole).
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.
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.
Sea star wasting syndrome is the largest marine disease event ever seen. Microbiologist Ian Hewson shares what inspires him to study oceanic ecosystems, and how scientists from Cornell University are solving this ecological mystery.
Part of "The Living Oceans" series. Captures the lives of sea stars that inhabit sea star gardens on the ocean bottom. Slow-motion photography reveals that predatory sea stars are actually social creatures that respond to one another's touch and prefer to hunt together. Illustrates animal defenses, such as camouflage in the octopus, and shows of aggression in the sarcastic fringehead.
This creature was found 1,800 feet deep in the ocean. It’s called a basket star. This extraordinary invertebrate has a mass of twisting and turning arms that can measure a meter long. Each branch has tiny sharp hooks allowing the creature to capture prey, and it feasts mainly on zooplankton. Basket stars are able to grow their limbs back if they are broken or chopped off by predators. Part of the "Creatures of the Deep" series.
When Carl Sagan was a young boy he went to the 1939 World's Fair. His life was changed forever, and from that day on he never stopped marveling at the universe and seeking to understand it better. As a child, Carl spent his days star gazing from the bedroom window in his Brooklyn apartment. As an adult, he became an internationally renowned scientist who worked on the Voyager missions. Based on the children's book by Stephanie Roth Sisson.
The engineers at NASA are studying two new technologies to help image distant Earth-like planets. Coronagraphs are tiny instruments fitted inside telescopes to block light and help scientists study clues as to whether life is present on a planet. Starshades also block light and produce clearer photographs of distant planets. Both of these technologies are used with telescopes and provide scientists with enhanced photographs of space. Part of the “Crazy Engineering” series.
Part of the "Branches on the Tree of Life" series. Echinoderms are one branch of the deuterostome line of animal evolution, the branch to which Chordates also belong. Covers phylum characteristics and key biological details for five classes: sea stars, brittle stars and basket stars, sea urchins and sand dollars (including developmental stages), sea cucumbers, and crinoids (feather stars).
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 kids arrive at a planet where only two elderly people are left. The rest of the population left because their sun is dying. Maqui explains to them that the sun is a star, and she teaches the life cycle of stars. The kids rescue the elderly pair and reunite them with the rest of their planet’s inhabitants. During this adventure, they learn the difference between planets and stars.
Features different systems of measurement and their value to science in five separate segments. Stardust Elements: Looks at the life cycles of stars and explains how the death of a star seeds the universe with all the elements of the periodic table. End of Dinosaurs: Debates several scientific theories about why and how dinosaurs became extinct. Earthly Thermometers: Demonstrates how the Fahrenheit, Celsius, and Kelvin scales measure the same thing in different ways and why we need precise measurements of temperature. Frozen in Time: Pieces together the past of a 5,300-year-old man whose body was preserved in ice in the Italian Alps. Hurricanes Take the Heat: Follows researchers who study how hurricanes form and try to predict where the next one will strike.
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. Ralphie's upset when his mom tells him he's too sick to go to school because he was supposed to host a FNN (Frizzle News Network) TV broadcast on health that day. Not one to leave a student behind, Ms. Frizzle takes the class on a trip inside Ralphie's body to figure out what's ailing him. However, once inside, Ralphie's white blood cells see the bus as a threat and start to attack.
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.
Features dozens of space professionals, from designers of space suits and life systems engineers to interior decorators and the "Lunar Lettuce Man." A touching story concerning famed teacher Jaime Escalante and one of his students is interwoven with imaginative vignettes that explore the humor and drama of day-to-day life away from Earth. Also stars Billy Bob Thornton, Kathy Bates, Jeffery Tambor, Jesse "The Body" Ventura, Raymond Cruz, Weird Al Yankovic, Vincent Schiavelli, and Pat Morita.
James Watson and Francis Crick collected and interpreted key evidence to determine that DNA molecules take the shape of a twisted ladder—a double helix. The film presents the challenges, false starts, and eventual success of their bold chase. Watson relates what those early days in the Cavendish Laboratory were like, including his friendship with Crick and their shared ambition and passion. Rarely seen archival footage is combined with interviews with some of today’s leading scientists to bring this landmark discovery and all of its implications to life.
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.
