World Almanac presents four outstanding documentaries covering the Big Bang creation theory of the universe, creation of the solar system, and search for extra-terrestrial life. Presented in a dramatic fashion that vividly captures the awe of creation and the mind-boggling expansion of the universe, these tapes depict the unfolding science through cosmologists who tell the story of mankind's search for sense in the heavens. It explains basic concepts, like the Doppler effect, in an easy to understand and concise manner.
A grand overview of the universe as we understand it and how it may evolve in the new millennium, this series reflects the youth and vibrancy of today's astronomers at the cutting edge of science. They scour for clues throughout the solar system and beyond to tell us not only where we've been, but perhaps where we are going. Using stunning, state of the art 3D graphics, The Expanding Universe also animates sequences from the structures of the Big Bang to the anatomy of the sun.
1 - The Big Bang
Long ago—some 12 billion years—our universe was formed in the Big Bang, an immense explosion that gave birth to countless galaxies, stars, and planets. Scientists today—trying to understand more about the origin and destiny of the Universe around us—have a better understanding than ever before of when and how the Big Bang took place. Learn the ways in which images from the Hubble Space Telescope have contributed to our knowledge of those first cosmic moments, and how current research is giving rise to theories about the universe's expansion and eventual end. Discover how cosmologists are closing in on answers to the greatest questions facing the human race: Where did we come from? Where are we now? And where will we ultimately go?
2 - The Sun And Other Stars
The really bright ball in the skies above the Earth is the Sun — a huge, turbulent ball of very hot gas that provides us with light which is both nurturing and potentially lethal. The Sun is but one of billions of stars in the Milky Way galaxy. All these stars have been born from interstellar dust and gas, only to die eventually. Stars can die violently, in a massive supernova explosion, or quietly, by shedding their outer atmospheres, which then form a planetary nebula. Learn how stars form, the fascinating stages they pass through during their life cycles, and how they ultimately die, turning from fledgling protostars to planetary nebulae, supernovae, neutron stars, and even black holes. Discover how some of the active stages of stars affect both them and the objects around them. And learn what the eventual death of our own Sun means for Earth and our solar system.
3 - The Planets
The solar system — the Sun and its collection of nine orbiting planets — formed some 5 billion years ago. We are now at the dawn of a new era in exploring those planets and answering some of the many questions about them. Already we have examined meteorites from other worlds for signs of life, landed men on the Moon, and launched spacecraft to look for evidence of volcanic eruptions on Mars and to explore the moons of Jupiter, as well as photographed all the planets in the solar system and launched probes to all except Pluto. Discover what the Voyager and Pioneer spacecrafts told us about the outer planets, and what the Viking, Pathfinder, Mariner and Magellan spacecraft have revealed about the inner planets. Perhaps what we accomplish in the next years will help pave the way for manned missions to Mars so that, eventually, people will walk on its surface as they have walked on the Moon.
4 - Searching For Other Life Forms
Human beings have long looked up at the sky and wondered: Are we alone? Are there other creatures like us? Is there intelligent life elsewhere in the universe? The answers may soon be at hand. Already, some scientists believe they have found microscopic fossils and other signs of life in a Martian meteorite, while researchers with sensitive telescopes are constantly tuned to the stars, listening for radio signals and laser light messages that might be sent by intelligent extraterrestrials. Moreover, we know now that life forms can exist in environments previously believed to be inhospitable, lending credence to the notion that life could well exist on other planets or moons despite their being considerably different from Earth. Learn how planned missions to Mars and Europa, one of Jupiter's moons, could bring back exciting answers to the question of whether there is life elsewhere in the Universe.
