Astronomy DVD -- Top 3 Features of a Great Astronomy DVD

A large number of astronomy DVDs contain images, videos, and fascinating facts about the universe. If you are enthusiastic about astronomy or if your kids are enthusiastic about astronomy, how would you select an interesting astronomy DVD that educates and entertains at the same time, given the vast choice of DVDs that are available on the topic of astronomy? Here are the top 3 features of a great astronomy DVD that you might want to consider: -

Genuine Astronomy Data and Images

The first thing to consider is the genuineness of the images and astronomical data on the DVD. Space exploration missions of NASA and ESA, the Hubble Telescope, and other unmanned deep space probes have collected vast amounts of fascinating information about the Universe. The representation of the Universe on any interesting astronomy DVD is based not only on real and high resolution images of the celestial bodies, but also on the precise positions, motions, and luminosity of the celestial bodies. Between 1989 and 1993, European Space Agency's "Hipparcos Project" (High Precision Parallax Collection Satellite Astrometric and Photometric Project) pinpointed the accurate positions, motions, and luminosity of over 100,000 stars and heavenly bodies. A good DVD about astronomy uses this data to create a realistic representation of the heavenly bodies in time and space.

Guided Virtual Tours Across the Universe

Hours of guided tours of the Solar System, the planets, all the moons of the planets, asteroids, comets, numerous distant galaxies, stars, red giants, white dwarfs, quasars, pulsars, black holes, etc. can be very entertaining and can educate both adults and children. Guided tours of the Universe are among the top 3 features of any good astronomy DVD. This feature makes learning astronomy easy and fun. It is easy to forget things that we read from magazines and books, but it is very easy to remember fascinating things that we enjoy watching.

Space Simulation Software

Without any doubt, a Space Simulator is the topmost feature of a great astronomy DVD. Imagine being able to take a flight from the surface of the Earth and fly across the Universe at hyper-speeds. A space simulation software uses the known astronomical data and images and creates a realistic three-dimensional representation of the Universe. It simulates a space ship flight from the Earth to any destination in outer space. Simulating the views of celestial bodies from different points in space and time, enabling a person to virtually orbit a heavenly body and view it from all angles in 3D, simulating how the universe might have looked in the past or how it might look in the future -- these are some of the other things that a space simulation software can do.

It is a space simulation software that enables an interesting astronomy DVD to provide answers to curious imaginations of the human mind. Have you ever wondered what our Earth looks like from the Moon? If it was possible to land on the surface of Jupiter, what would the spectacle of multiple Moons of Jupiter look like on the horizon of Jupiter? If we could survive just a few thousand miles away from the Sun, what would the Solar Flares of the Sun look like? What would our 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.
