- "THE DIGITAL UNIVERSE"
- Astronomy Software for the Amiga Computer
- 1995/12/01
-
-
- PRODUCT DESCRIPTION
- -------------------
- "The Digital Universe" is a complete astronomy program for the amateur
- or professional observer. It combines the advantages of traditional
- "planetarium" programs with a massive hypertext multimedia encyclopedia
- to create an effective tool which assists the user in observing and
- learning about the heavens. 50,000 lines of code, more than 700 pages
- of hypertext, and thousands of man-hours have gone into this product to
- make it the most complete program of its class. The software would not
- have been possible without the generous assistance of countless
- individuals from the Canadian Space Agency, the National Research
- Council of Canada, NASA, JPL, NORAD, the European Space Agency, the
- Bureau des Longitudes, the Smithsonian Astrophysical Observatory, the
- Russian Academy of Sciences, and several other organizations worldwide.
-
-
- PRODUCT FEATURES
- ----------------
- The following features by no means summarize all the things which
- the software is capable of. Due to space considerations, only the
- major features can be summarized here.
-
- - The following databases are integrated into the software:
- 1. Yale Bright Star (YBS) Catalogue of 9110 stars.
- 2. Smithsonian Astrophysical Observatory (SAO) Catalogue of over
- 250,000 stars.
- 3. Messier's Catalogue of 110 deep sky objects (galaxies,
- nebulae, and clusters).
- 4. Sky & Telescope's NGC 2000.0 Catalogue of 13,226 deep sky
- objects.
- 5. Tom Lorenzin's "1000+" database of observing comments for
- over 2000 objects.
- 6. Jost Jahn's comet database containing 2298 cometary orbits.
- 7. Jost Jahn's minor planet database containing orbital
- information for thousands of asteroids.
- 8. Ted Molczan's and T. S. Kelso's orbital information for
- approximately 900 Earth-orbiting satellites.
-
- - The software can generate accurate views of the night sky for any date
- from 100,000 BC to 100,000 AD.
-
- - The package includes over 700 pages of hypertext, including an
- introduction to astronomy, dictionary of terms, biographies of famous
- people, celestial object descriptions, and summaries of every
- interplanetary spacecraft launched to date.
-
- - More than 250 pictures are linked into the hypertext encyclopedia.
- They include images of all the planets, most of their satellites, all
- of the Messier objects, some NGC objects, and many miscellaneous
- images. A few audio clips are incorporated as well.
-
- - A context-sensitive help system, linked into the online encyclopedia,
- is integrated into the software.
-
- - The user can select whether or not they want to consider effects such
- as precession, proper motion, nutation, aberration, or refraction.
-
- - "The Digital Universe" uses the latest analytic theories of motion for
- the planets (VSOP87) and their satellites, resulting in typical
- accuracies of better than 1 arcsecond (1/3600th of a degree).
-
- - The current analytic theory of motion for the moon (ELP2000-85) has
- been extended to improve its accuracy even further for times within
- a few hundred years of the present. The extension was done specifically
- for "The Digital Universe".
-
- - NORAD's SGP4 model of orbital motion is used to accurately predict
- the apparent positions and movement of Earth-orbiting satellites.
- "The Digital Universe" can work with standard "2-line" orbit files.
- Hundreds of satellites are included with the software, and information
- is provided to explain how to obtain future data sets as new
- satellites are launched and older orbits decay.
-
- - Unlike many other astronomy programs which only consider the four
- brightest satellites of Jupiter, "The Digital Universe" accurately
- computes orbits for the moons of:
- Earth: Our Moon
- Mars: Phobos and Deimos
- Jupiter: Io, Europa, Ganymede, Callisto, Amalthea, and Thebe
- Saturn: Mimas, Enceladus, Tethys, Dione, Rhea, Titan, Hyperion,
- Iapetus, Phoebe, Telesto, Calypso, and Helene
- Uranus: Miranda, Ariel, Umbriel, Titania, and Oberon
- Neptune: Triton and Nereid
- Pluto: Charon
- When the software is zoomed in sufficiently to the planet of
- interest, the moons are rendered in their proper positions.
-
- - When zoomed in to most planets and satellites, the object's
- orientation and phase is determined and a latitude/longitude grid
- superimposed if the user desires. Maps of Venus, the Moon, Mars,
- Jupiter, and Saturn are incorporated into the software to generate
- accurate renditions of the appearance of these objects. The ring
- systems of Saturn and Uranus are rendered.
-
- - Supports the Amiga preferences printer. Plots of star charts, etc.
- are far more than a simple screen dump. The maximum resolution of
- the printer is used for outstanding clarity.
-
- - The user can enter his or her own horizon, if desired. Horizons for
- multiple observing sites can be configured.
-
- - The user can select their location from a list of over 1000 cities,
- or enter their latitude, longitude, and altitude above sea level
- manually if higher accuracy is desired.
-
- - Completely configurable IFF animations can be generated. To mention
- just two examples from the infinite number of possibilities, you
- can see how stars move and constellations distort over centuries, or
- view how Saturn's rings change their orientation and appearance over
- time. "The Digital Universe" can also save screen snapshots as ILBMs.
-
- - A report generation feature lets you choose between a wide variety
- of data and customize tabular reports. They may either be printed
- or saved to disk.
-
- - Provided that you have sufficient chip memory, the screen upon which
- "The Digital Universe" runs can be of any size. If the screen is
- larger that can fit on the monitor, you can scroll around simply by
- moving your mouse to the edge of the visible area. A screenmode
- requester is provided to allow users to specify their particular
- monitor.
-
- - All development was done entirely on Amiga. It is not a port from
- the IBM or Macintosh world. As a result, the software closely
- adheres to the Amiga style guidelines and behaves in the manner you
- would expect from Amiga software.
-
-
- SYSTEM REQUIREMENTS
- -------------------
- The software will run on any Amiga with Workbench 2.04 or greater, at
- least 3 megabytes of memory, and a minimum of 11 megabytes of hard drive
- space (17 megabytes of hard drive space is required for a full
- installation). Due to the extremely calculation-intensive nature of
- this software, an accelerated Amiga and math chip (FPU) is strongly
- recommended, though not required.
-
-
- ORDERING INFORMATION
- --------------------
- There are two packages which may be of interest to the amateur
- astronomer. First and foremost is "The Digital Universe" software
- itself, which comes provided with a 138 page user manual. Secondly,
- in the process of creating the package, more than 700 pages of a
- hypertext multimedia encyclopedia was created (the electronic version
- of which is shipped with the software). However, since many individuals
- prefer reading from paper than the computer screen, a printed version
- of this information is also available.
-
- The prices of "The Digital Universe" software and printed encyclopedia (as of
- November 1, 1995) can be found in the following table. All prices include
- shipping and handling, and Canadian prices include 7% GST. Note that the
- prices for Canadian orders are quoted in Canadian dollars, UK orders are quoted
- in British pounds, and US and other international orders are quoted in US
- dollars.
-
- If you are an educational user, or a member of an Amiga user group, you qualify
- for a 15% reduction in the prices appearing below. Contact us for further
- details. Prices and promotions are subject to change without notice.

- fluctuations between the time of purchase and the time your credit card company
- processes the transaction, the actual amount may be a few dollars more or less
- than that quoted above. However, the prices will be accurate for cheque or
- money order transactions.
