More than 2½ hours of original movies unveil the marvelous world of astronomy.

As a primer on up-to-date scientific theory about the nature of the universe and our place in it, Cosmic Voyage is visually sumptuous and just plain fun. Shot in the mind-blowing IMAX process, this combined live-action and computer-generated production has (even in video format) an immensity of scope befitting its grand subject. Beginning, lyrically if unexpectedly, in Italy's magnificent Venice, Cosmic Voyage draws inspiration from airborne perspectives on the city's famed network of canals and streets, leading to further appreciations of dense systems in nature. From the subnuclear to the physical limits of the known universe, Cosmic Voyage explores a resonance between all things while making sense of such inscrutable phenomena as the birth of stars and planets, black holes, supernovas, etc. The marvels of cosmology are rarely so accessible as this.

In the course of 13 fascinating hours, Cosmos spans its own galaxy of topics to serve Sagan's theme, each segment deepening our understanding of how we got from there (simple microbes in the primordial mud) to here (space-faring civilization in the 21st century). In his "ship of the imagination," Sagan guides us to the farthest reaches of space and takes us back into the history of scientific inquiry, from the ancient library of Alexandria to the NASA probes of our neighboring planets. Upon this vast canvas Sagan presents the "cosmic calendar," placing the 15-billion-year history of the universe into an accessible one-year framework, then filling it with a stunning chronology of events, both interstellar and earthbound.....What's most remarkable about Cosmos is that it remains almost entirely fresh, with few updates needed to the science that Sagan so passionately celebrates.

Based on Brian Greene's book, this three-part Nova program should do for physics what Cosmos did for astronomy. Greene hosts the program on the relative new concept of String Theory, a potential (and explosive) answer to the Holy Grail of science: a single, ultimate theory for everything. Part of Greene's (along with filmmakers Julia Cort and Joseph McMaster) genius is the ability to explain complex issues with ease thanks to a generous helping of graphics and humor. It starts with a perplexing anecdote: Einstein died trying to figure out if there could be an ultimate theory. His General Theory of Relativity brought order to the laws of large objects, but could not explain the chancier world of Quantum Mechanics (which deals with atomic particles). String Theory tries to marry the two. Greene and many colleagues give us a history of the quest and how String Theory was "discovered" in the 1980s. The formula has a lot of quirks, the most dazzling being the insistence there's 11 dimensions in the universe. Greene is not as natural as Cosmos creator/host Carl Sagan, but he is certainly friendly and encouraging (albeit it's quite odd for the host to be interviewed at various times in the program). Because it's a three-part show, there is some overlap at the start of hours 2 and 3.

Explore the mysterious past and fascinating future of the Red Planet.

The great PBS science series Nova scores another hit with Mars: Dead or Alive, capturing all the excitement surrounding the Mars rover landings of early 2004. Originally broadcast just as the first of the twin rovers ("Spirit" and "Opportunity") was experiencing temporary communication problems with Earth-bound mission controllers, this riveting hour-long episode chronicles the risky $820 million Mars Exploration Rover (MER) project from design to touchdown, dramatically illustrating (through the use of detailed simulations and sophisticated computer animation) the considerable chances of failure--a nail-biting gamble considering that fully two-thirds of all previous Mars missions never reached their destination. Through rigorous testing and initial failure of the MER parachute system to the celebrated transmission of pristine photos from the "Spirit" landing site, we see just how intensely complex and emotionally involving the missions are, especially for Cornell University astronomer and lead MER scientist Steve Squyres and his devoted team of colleagues at Pasadena's Jet Propulsion Laboratory. Careers are on the line as technical problems accumulate, and one feels the same mixture of dread, anxiety, and elation that accompanied the historic return of Apollo 13. A bonus interview with Mars-mission pioneer Donna Shirley puts everything into resonant perspective, celebrating science and the MER missions as an essential human endeavor.

As with all Nova programs, the DVD includes a generous variety of study materials including an interview with Squyres, a detailed look at the anatomy of the Mars rovers, links to a companion website, and a "math activity" feature allowing viewers to understand the aerodynamic variables of parachute design. If you're among those who feel that NASA and MER tax dollars are wasted, this DVD will probably change your opinion.

The word "interactive" gets bandied about quite a bit in the DVD world, but here's a disc that simply wouldn't work without interactivity. While there is an "Entertainment Mode" on the disc that lets the viewer passively experience a 90-minute presentation of video clips, the real indispensable part is the "Interactive Mode," which contains a wealth of information on the Red Planet that any self-respecting Mars aficionado will crawl, beg, or steal to possess. Detailed information on NASA missions abounds, including video clips and simulations of some missions. Views of Mars, in 3-D (glasses included) or not, provide a 360-degree panorama from landing several sites. Even the famous Face on Mars is featured in a section called "Martian Coronae." But the most valuable section of the disc is its "Interactive Maps," allowing the user to hop around the planet and zoom in on any area of interest. This feature alone could cause any Mars-lover to lose track of time. Also included is an art gallery featuring artists' conceptions of Mars, along the lines of what it would be like during colonization. Accompanying the many videos and views of the planet is an electronic version of Holst's The Planets, performed by Ryan Shore. With all this and DVD-ROM features to boot, it would be exceedingly hard to get bored. A must-have for anyone interested in Mars.

This two-sided DVD is split into two segments: "Destination: Mars" and "Life on Mars." The second, graced with John Lithgow's narration, discusses the study of a seemingly insignificant rock: meteorite ALH84001. The meteorite, discovered by a team of researchers in the Antarctic, contains indications of primitive life forms that may have lived long, long ago on the red planet. There's copious information about the scientific methods used to analyze the rock, and the meteorite's origins. The rather long-winded breakdown is leavened by a segment on the "traditional" views of life on Mars, dating back to H.G. Wells. Fans of 1950's science fiction will recognize clips from Red Planet Mars, Plan 9 from Outer Space, Santa Claus Vs. the Martians, Angry Red Planet, and several other movies during a tongue-in-cheek montage. A Jesuit priest who doubles as an astronomer posits some compelling questions about the ways in which the knowledge of life on other planets may affect the way we Earthlings view ourselves and our place in the universe.

"Destination: Mars" documents efforts to contact the red planet, and goes into the current state of the art of space-travel technology for humans. Things are still in a fairly primitive state when it comes to exploring Mars via robot; the time delays involved in sending or receiving information from the planet's surface make something as simple as examining a rock agonizingly slow. The impetus to put people on Mars has cooled considerably since the end of the Cold War. Without the budgets and public enthusiasm that went into the '60s space race, the Mars effort has been on the back burner. That doesn't mean, however, that it's been shelved; a corps of scientists and researchers are still lobbying to put people on its moon by 20l7. Plants can be used for both food and oxygen; human waste can be distilled and recycled into drinking water (see if you don't cringe when a scientist takes a long drink of a sample).


Though the amount of detail and length of Mars: The Red Planet Collection can be a bit daunting, there's still a wealth of knowledge shared here for science-minded space buffs.

Where did it all begin? How did the universe give birth to the sun and its family of planets that form our solar system? How is a bubbling atomic reactor in space the source of warmth and light for life as we know it? Why will Mars be the first planet we colonize? What is the long-term fate of the planets in our solar system? Are we alone? The Planets is an entertaining, comprehensive, and informative A&E documentary series that sets out to answer many of life's most physically existential questions. This series combines scientific history of early scientists, rich knowledge from the leading minds in modern astronomy, and extraordinary image technology to tell the story of our solar system, from its beginnings to the present and beyond. The topics are: "Different Worlds," "Terra Firma," "Giants," Moon," "Star," "Atmosphere," "Life Beyond the Sun," and "Destiny." From the sweltering rocky surface of Mercury to the violent stormy skies of Jupiter to the cold, mysterious land of Pluto, The Planets is a fascinating exploration of discovery and adventure for anyone who has looked up into space on a starry night in total amazement

"StarGaze" brings the beauty and majesty of the universe to your home theater, direct from the Hubble Space Telescope. With over an hour of the most incredible images of the universe you'll ever see, from gaseous clouds to more than 200 other astronomical objects, plus Dolby Digital and DTS surround sound music from popular new age group 2002, "StarGaze" will quickly become a favorite in your DVD collection.....It looks like all that money NASA spent on the Hubble Space Telescope was worth it after all--at least from an aesthetic standpoint. Stargaze: Hubble's View of the Universe captivates the viewer with stunningly high-definition color images of galaxies, nebulae, and heavenly bodies closer to home. Each shot pans and lingers over the richly colored pictures as unobtrusive narration in English, French, German, or Spanish explains the history of the Hubble mission, its targets, and what we've learned so far

Stargaze II doesn't deviate much from the previous Stargaze DVD, and that's a good thing. Galaxies, nebulae, and other astronomical elements simply float across the screen in brilliant clarity, fueled by New Age music by Opus 27. The images are mostly from the Hubble Space Telescope, along with some unique mosaics from several sources. The bigger your screen, the better for "plasma art" that could serve as the background at a party or a valentine to any star freak. You can even view the program in high definition if you have the right media set-up. Sometimes the images float in front of a wallpaper of stars that causes a 3-D effect or looks kinda hokey, depending on your point of view. You can find out what you are looking at by activating subtitles or by clicking a menu button that goes to a page-by-page detail about the subject and how the image was rendered. With literally out-of-this-world colors and textures, the beauty of the heavens is glorious to behold. Produced the same year Congress debates the fate of the Hubble (2004), this program serves record of the extraordinary worlds that are seen only by this workhorse satellite. Lobbyists may have no better weapon to use than the Stargaze DVDs.

He is a living legend, whose book A Brief History of Time became an instant best seller. Now, his genius is fully revealed in this new series that will treat you to the latest and most profound advances in cosmological thought in true down-to-earth Hawking fashion. Encompassing Hawking's matchless point of view, these six programs spin an intergalactic detective story, rich with mystery, unexpected twists and astonishing revelations.

This engaging two-hour documentary from NOVA detailing America's space program was produced for the 30th anniversary of the first moon shots. While no 120-minute film can tell all the stories of the space program, To the Moon is more comprehensive than other similar videos. The film details the method that Americans used to reach the moon: lunar orbit rendezvous (one ship circles the moon while another lands). This concept wasn't even on the drawing board at NASA, and the video chronicles the struggle of engineers and astronauts to work out a solution. The space footage focuses on Gemini missions that rehearsed rendezvous in space and the most extravagant Apollo missions (numbers 8, 11, 13, 15, and 17). The film reunites several astronauts for fresh perspectives on the importance of the program, including the knowledge gained about the geology of the moon. Generation X actor Liev Schreiber (Scream 2) supplies the narration for this video, which is a great companion to the From the Earth to the Moon miniseries.

Join astronomers and astrophysicists as they probe light years beyond the Milky Way, in Understanding The Universe, part of TLC's popular television series. Narrated by actress Candice Bergen, This enriching and entertaining video employs graphic models and spectacular computer animation to illustrate some of the most complex theories of all time. Peer through the largest telescopes on Earth. Get a close-up look at our sun, nebulas and supernovas, capture by the Hubble Space Telescope. Listen via satellite to echoes of the Big Bang. See how "red Shift" among the stars suggests that our universe if much younger than previously thought. Visit the set of Star Trek: Voyager and ponder the questions, could black holes be "worm holes," or shortcuts to other worlds? Understanding the Universe boldly goes where no television show has gone before.

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.
