If you are an astronomy enthusiast, you might have come across a large number of DVDs about the universe. Good universe DVDs contain images, videos, and fascinating facts about the universe. How to select an interesting universe DVD that can educate and entertain you at the same time? Here are the top three characteristics that can be expected from an interesting DVD about the universe and outer space: -
Interesting Images and Real Data of the Universe
Esa
A good universe DVD contains high resolution images of celestial bodies and real data about the precise positions and motions of the celestial bodies. During the past few decades large amounts of astronomical data have been gathered by space exploration missions of NASA and other space agencies. Powerful telescopes, man-made satellites, and deep space probes have captured astonishing, high-resolution images of celestial bodies. The Hipparcos (High Precision Parallax Collection Satellite) astrometric and photometric Project of the European Space Agency (ESA) pinpointed the accurate positions, motions, and luminosity of over 100,000 stars and heavenly bodies between 1989 and 1993. This data enables us to create a realistic representation of the heavenly bodies in time and space.
Guided Tours of the Universe
Virtual guided tours of the universe are a source of great entertainment and education for both adults and children. An interesting universe DVD can contain hours of guided tours of all the planets and their moons, the Solar System, and the rest of the universe. Videos and other forms of audio-visual presentations make learning astronomy easy and fun. We can easily forget what we read, but it is much easier to enjoy and remember mind-blowing facts about the universe that are presented in the form of guided tours.
Space Simulation Software
This can be the ultimate feature of a good universe DVD. A space simulation software can manipulate images and known data about the universe to simulate a journey from the Earth to any destination in outer space. It can simulate views of celestial bodies from different points in space and time. It can enable a person to virtually orbit a heavenly body at hyper-speed and view it in 3-dimensions from all angles.
Space simulation software enables a good universe DVD to provide answers to curious imaginations of the human mind. How does the Earth look from the Moon? What would the multiple moons of Jupiter look like if one were to see them from the surface of Jupiter? What would the Solar Flares of the Sun look like if we were to view them from a few thousand miles from the Sun? What would the Solar System look like if we were to view it from a far away place in outer space? What would the Milky Way look like if we were to see it from another distant galaxy? All these questions can be answered as realistically as possible by a good space simulation software that makes calculations based on known visual, mathematical, and other scientific data about the universe.
