Highlights the limited information scientists have about the many moons in our solar system. Presents theories of origin and composition. Mixes graphics with pictures taken from spacecrafts.
Professor Jim Al-Khalili shows that in our quest to understand the tiny atom, we unraveled the mystery of how the entire universe was created. It's a story with dramatic twists and turns, taking in world-changing discoveries like radioactivity, the Atomic Bomb, and the Big Bang Theory. All this forms part of an epic narrative in which the greatest brains of the 20th century competed to answer the biggest questions of all-why are we here and how were we made?
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.
This program discusses the concept of the expanding universe. Calculations by astrophysicists show that the cosmos seems to be speeding up. The 50-billion galaxies thought to comprise our universe are rapidly moving farther apart. Scientists are working to understand the nature of space and the purpose of dark energy and dark matter related to the expanding universe.
Are planets still being formed? Dr. Debra Fischer answers this and other questions about the Cosmos. Part of the "Ask a Scientist" series.
For many years the Hubble Space Telescope has collected breathtaking images of the cosmos with remarkable clarity. Now, ground based telescopes are fighting back. They are combining the precision of several instruments and correcting for atmospheric shimmer. This program presents and explains the designs, uses, and outputs of different types of telescopes.
How far is a star or a galaxy? Scaling and measuring the cosmos is a complex problem. Scientists are integrating mathematical applications and scientific technology to create measurement standards. Distances are so vast they are described in light years, and nearby stars are measured by trigonometry. Farther out, astronomers use standard candle measurement for deep space exploration.
Take a high performance ride through the formation of the third planet from the Sun. Learn how Earth was created and discover what creatures hold clues to how life began. What evil forces threaten the demise of Earth? Complex and controversial, this is the scientific detective story of all time. Cutting-edge graphics are used along with the stories of scientists and explorers who dare to venture into the uncharted territory of the cosmos.
The Very Large Array, or VLA, is a complex of 27 massive antennas on the Plains of San Agustin in central New Mexico, all pointing skyward to monitor radio emissions from the cosmos. With support from the National Science Foundation, astronomers use this facility to observe the most dynamic, cataclysmic events in the universe. Part of the "Science Nation" series.
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.
