Cartes Du Ciel
''Cartes du Ciel'' ("CDC" and "SkyChart") is a free and open source planetarium program for Linux, macOS, and Windows. With the change to version 3, Linux has been added as a target platform, licensing has changed from freeware to GPLv2 and the project moved to a new website. CDC includes the ability to control computerized GoTo telescope mounts, is ASCOM and INDI compliant, and supports the USNO's UCAC catalogs and ESA Gaia data, along with numerous other catalogs and utilities. The "red bulb" feature is useful when using software outside on a laptop on a dark night. According to the programmer, Patrick Chevalley, it was released as freeware because "I’d rather see amateurs spend their money for a new eyepiece than for astronomy software". Chevalley has also created a lunar atlas program, ''Virtual Moon Atlas'', which is also free and open source software.

Object Pascal
Object Pascal is an extension to the programming language Pascal (programming language), Pascal that provides object-oriented programming (OOP) features such as Class (computer programming), classes and Method (computer programming), methods. The language was originally developed by Apple Computer as ''Clascal'' for the Apple Lisa, Lisa Workshop development system. As Lisa gave way to Macintosh, Apple collaborated with Niklaus Wirth, the author of Pascal, to develop an officially standardized version of Clascal. This was renamed Object Pascal. Through the mid-1980s, Object Pascal was the main programming language for early versions of the MacApp application framework. The language lost its place as the main development language on the Mac in 1991 with the release of the C++-based MacApp 3.0. Official support ended in 1996. NortonLifeLock, Symantec also developed a compiler for Object Pascal for their Think Pascal product, which could compile programs much faster than Apple's ow ...

Gaia (spacecraft)
''Gaia'' is a space observatory of the European Space Agency (ESA), launched in 2013 and expected to operate until 2025. The spacecraft is designed for astrometry: measuring the positions, distances and motions of stars with unprecedented precision. The mission aims to construct by far the largest and most precise 3D space catalog ever made, totalling approximately 1 billion astronomical objects, mainly stars, but also planets, comets, asteroids and quasars, among others. To study the precise position and motion of its target objects, the spacecraft monitored each of them about 70 times over the five years of the nominal mission (2014–2019), and continues to do so during its extension. The spacecraft has enough micro-propulsion fuel to operate until about November 2024. As its detectors are not degrading as fast as initially expected, the mission could therefore be extended. ''Gaia'' targets objects brighter than magnitude 20 in a broad photometric band that covers the e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Science Software For Windows
Science is a systematic endeavor that builds and organizes knowledge in the form of testable explanations and predictions about the universe. Science may be as old as the human species, and some of the earliest archeological evidence for scientific reasoning is tens of thousands of years old. The earliest written records in the history of science come from Ancient Egypt and Mesopotamia in around 3000 to 1200 BCE. Their contributions to mathematics, astronomy, and medicine entered and shaped Greek natural philosophy of classical antiquity, whereby formal attempts were made to provide explanations of events in the physical world based on natural causes. After the fall of the Western Roman Empire, knowledge of Greek conceptions of the world deteriorated in Western Europe during the early centuries (400 to 1000 CE) of the Middle Ages, but was preserved in the Muslim world during the Islamic Golden Age and later by the efforts of Byzantine Greek scholars who brought Greek man ...

Educational Software For Windows
Education is a purposeful activity directed at achieving certain aims, such as transmitting knowledge or fostering skills and character traits. These aims may include the development of understanding, rationality, kindness, and honesty. Various researchers emphasize the role of critical thinking in order to distinguish education from indoctrination. Some theorists require that education results in an improvement of the student while others prefer a value-neutral definition of the term. In a slightly different sense, education may also refer, not to the process, but to the product of this process: the mental states and dispositions possessed by educated people. Education originated as the transmission of cultural heritage from one generation to the next. Today, educational goals increasingly encompass new ideas such as the liberation of learners, skills needed for modern society, empathy, and complex vocational skills. Types of education are commonly divided into formal, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Planetarium Software For Linux
A planetarium ( planetariums or ''planetaria'') is a theatre built primarily for presenting educational and entertaining shows about astronomy and the night sky, or for training in celestial navigation. A dominant feature of most planetariums is the large dome-shaped projection screen onto which scenes of stars, planets, and other celestial objects can be made to appear and move realistically to simulate their motion. The projection can be created in various ways, such as a star ball, slide projector, video, fulldome projector systems, and lasers. Typical systems can be set to simulate the sky at any point in time, past or present, and often to depict the night sky as it would appear from any point of latitude on Earth. Planetaria range in size from the 37 meter dome in St. Petersburg, Russia (called “Planetarium No 1”) to three-meter inflatable portable domes where attendees sit on the floor. The largest planetarium in the Western Hemisphere is the Jennifer Chalsty Plan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Planetarium Software
Planetarium software is application software that allows a user to simulate the celestial sphere at any time of day, especially at night, on a computer. Such applications can be as rudimentary as displaying a star chart or sky map for a specific time and location, or as complex as rendering photorealistic views of the sky. While some planetarium software is meant to be used exclusively on a personal computer, some applications can be used to interface with and control telescopes or planetarium projectors. Optional features may include inserting the orbital elements of comets and other newly discovered bodies for display.

List Of Space Flight Simulation Games
This is a sourced index of commercial, indie and freeware space flight simulation games. The list is categorized into four sections: space flight simulators, space flight simulators with an added element of combat, space combat simulators with an added element of trading, and unreleased space flight simulators. A space flight simulator game is software that allows the operator to experience spacecraft space flight in outer space with the added elements of gameplay. There are many different types of simulators. These simulators range in purpose from pure simulation to sheer entertainment. Space flight occurs beyond the Earth's atmosphere, and space flight simulators feature the ability to roll, pitch, and yaw. Space flight simulators use flight dynamics in a free environment; this free environment lets the spacecraft move within the three-dimensional coordinate system or the x, y, and z (applicate) axis. :See Lists of video games for related lists.
