README.TXT CyberSky Shareware Version 1.0b Thursday, July 6, 1995 Description of CyberSky ----------------------- CyberSky is a colorful, easy-to-use program that transforms your computer screen into a planetarium, allowing you to learn about astronomy by exploring the sky in the past, present, and future. CyberSky can truly be thought of as a desktop planetarium, because it duplicates the features of a traditional planetarium on your computer screen. CyberSky provides a superb, innovative, and motivating learning environment. It places the sky under your control. One of CyberSky’s most powerful and educational features is its ability to animate the display, allowing you to see animations of the changing appearance of the sky over time. Many of the most basic and interesting astronomical phenomena can only be observed over days or months of time, or by observing the sky in the distant past or future. CyberSky compresses these time spans into minutes, thereby allowing you to learn things about astronomy that previously would have required days or weeks of stargazing or a trip to a planetarium to learn. CyberSky allows you to o View the positions of the sun, moon, and all planets of the solar system in the sky. Information about those objects, such as their distances from the earth, and their rising and setting times are available by simply clicking on them with the right mouse button. o View 5080 stars. Information about those stars, such as their Bayer and Flamsteed designations, magnitudes, spectral types, and rising and setting times are available by simply clicking on them with the right mouse button. Proper names are available for 248 of the brightest stars. o View constellation lines for all 88 constellations. o Display reference lines such as the ecliptic, celestial equator, galactic equator, and equatorial coordinate system grid. o Display the north and south poles of the ecliptic, celestial equator, and galactic equator. o Choose to view the sky from any location on the earth between the years 4000 BC and 4000 AD. o Understand the dynamics of the sky by performing the steps in the Explorations section of the help file. You will be able to learn about such topics as precession of the equinoxes, proper motion, and retrograde motion of planets not by reading a description but by watching CyberSky’s simulated sky. o Learn astronomical terminology by reading through the help file’s extensive glossary section. o Print the display in either black on white or in color to create your own star charts you can use to identify stars, constellations, and planets in the night sky. If you have an interest in astronomy, CyberSky will provide hours of fun and education for you and your family.

If you are installing CyberSky on a networked Windows system, you must type C:\DIR\INSTALL.EXE /N instead. 4 Choose the OK button and follow the installation program’s instructions. After CyberSky has been successfully installed, be sure to save the distribution file on your hard disk or on a diskette. You will need this file if you want to reinstall CyberSky or want to uninstall it.
