Have you ever looked at the stars twinkling in the sky and wondered what’s out there? If you are an astronomy enthusiast, you may have looked at celestial bodies through a telescope. You may have also read astronomy books to learn the facts about the universe. Fascinating facts about the universe and guided space tours can also be found on any astronomy DVD in the form of videos, multimedia files, and space simulation software.
As computers have become more popular, more and more information is available in the form of rich multimedia presentations that make learning easy and fun. The large storage capacity of a DVD makes it possible to include several hours of audio and video about the universe on an astronomy DVD. Guided space tours may contain high-resolution images that have been collected over the years by NASA space exploration missions and other space agencies. Some of the data includes surface images of planets and their moons collected by NASA deep space probes and other space agencies.
Between 1989 and 1993, the European Space Agency (ESA) identified the precise positions and motions of more than 100,000 stars and other celestial bodies. This project was known as the Hipparcos project. Hipparcos is an acronym for “High Precision Parallax Collection Satellite”. Some software programs that simulate trips to outer space use this data in the form of a huge database on an astronomy DVD. A space simulator software allows a person to take virtual trips into outer space at hypervelocity and view celestial bodies from different angles and positions in space. It is also possible to simulate a view of the universe as it might have been in the past or as it might look in the future. Multimedia and simulations are some of the advantages of an astronomy DVD over traditional astronomy books.
For an astronomy enthusiast, explore interesting astronomical phenomena and discover the mysteries of celestial bodies such as the Sun, the Moon, planets, asteroids, comets, stars, galaxies, etc. they usually require powerful, sophisticated telescopes and voluminous astronomy books, both of which can be expensive and often require expert guidance. On the other hand, the ease with which a multimedia astronomy DVD can be manufactured and the amount of information that can be stored on it makes it an inexpensive but very informative astronomy guide.
If we go to a planetarium, we are confined to our seats where we sit and passively watch the celestial bodies on a screen. On the other hand, space simulation software present on an astronomy DVD allows us to take a virtual flight from Earth into outer space and travel at hyperspeed through the solar system and even outside the Milky Way to other distant galaxies. Guided tours on an astronomy DVD can entertain and educate. We can discover faraway worlds that most people don’t even know exist.
An astronomy DVD is equally suitable for both professional astronomers and schoolchildren who want to gain knowledge in an easy and entertaining way. It is a well known fact that we retain more information from audiovisual presentations than from books.
