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 The sky is an unobstructed view upward from the planetary surface, surface of the Earth. It includes the atmosphere of Earth, atmosphere and outer space. It may also be considered a place between the ground and outer space, thus distinct from .... 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.

Application Software
Application software is any computer program that is intended for end-user use not operating, administering or programming the computer. An application (app, application program, software application) is any program that can be categorized as application software. Common types of applications include word processor, media player and accounting software. The term ''application software'' refers to all applications collectively and can be used to differentiate from system and utility software. Applications may be bundled with the computer and its system software or published separately. Applications may be proprietary or open-source. The short term ''app'' (coined in 1981 or earlier) became popular with the 2008 introduction of the iOS App Store, to refer to applications for mobile devices such as smartphones and tablets. Later, with introduction of the Mac App Store (in 2010) and Windows Store (in 2011), the term was extended in popular use to include desktop a ...

HNSKY
HNSKY or Hallo Northern Sky is a free and open-source planetarium program for Linux, macOS, Microsoft Windows, and Raspberry Pi to simulate the night sky. It is provided with several non-English language modules, numerous astronomical catalogues, conversion utilities and tools, as well as several stellar databases. HNSKY was created in 1998 by Dutchman Han Kleijn, who continues to develop and maintain the application. It is available in both 32 bit and 64 bit versions. Initially a basic planetarium program, it has expanded in functionality to include the ability to control computerized GoTo telescope mounts. It is ASCOM and Instrument Neutral Distributed Interface (INDI) compliant, and supports the United States Naval Observatory's USNO CCD Astrograph Catalog (UCAC) catalogs, and European Space Agency Gaia data.

Digistar
Digistar is the first computer graphics-based planetarium projection and content system. It was designed by Evans & Sutherland and released in 1983. The technology originally focused on accurate and high quality display of stars, including for the first time showing stars from points of view other than Earth's surface, travelling through the stars, and accurately showing celestial bodies from different times in the past and future. Beginning with the Digistar 3 the system now projects full-dome video. Projector Unlike modern full-dome systems, which use LCD, DLP, SXRD, or laser projection technology, the Digistar projection system was designed for projecting bright pinpoints of light representing stars. This was accomplished using a calligraphic display, a form of vector graphics, rather than raster graphics. The heart of the Digistar projector is a large cathode-ray tube (CRT). A phosphor plate is mounted atop the tube, and light is then dispersed by a large lens with a 160 deg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Google Sky
Google Earth is a web mapping, web and computer program created by Google that renders a 3D computer graphics, 3D representation of Earth based primarily on satellite imagery. The program maps the Earth by superimposition, superimposing satellite images, aerial photography, and geographic information system, GIS data onto a 3D globe, allowing users to see cities and landscapes from various angles. Users can explore the globe by entering addresses and coordinates, or by using a Computer keyboard, keyboard or computer mouse, mouse. The program can also be downloaded on a smartphone or Tablet computer, tablet, using a touch screen or stylus to navigate. Users may use the program to add their own data using Keyhole Markup Language and upload them through various sources, such as forums or blogs. Google Earth is able to show various kinds of images overlaid on the surface of the Earth and is also a Web Map Service client. In 2019, Google revealed that Google Earth covers more than 97 ...

XEphem
XEphem is a Motif based ephemeris and planetarium program for Unix-like operating systems developed by Elwood C. Downey. History XEphem started as a Unix and Motif conversion of the IBM PC-based '. It was initially released in December 1993 with version 2.5. Its commercial edition was discontinued in 2016; the free version continued to be offered as proprietary software. In 2021, however, Downey relicensed XEphem's source code under the MIT License, raising the release version from 3.7.7 to 4.0.0 to highlight the change. Algorithms and models XEphem uses * The VSOP87D planetary theory (full and reduced precision) for Solar System ephemeris, * Approximation to DE200 for the outer planets and Pluto, and * Formulae from J. Meeus (1982) for Jovian and Saturnian natural satellites * Model by the Bureau des Longitudes for Martian and Uranian natural satellites and includes * About 452 million stars from both the Tycho-2 Catalogue and a magnitude limited subset of the Guide Star Cata ...

SpaceEngine
SpaceEngine is an interactive 3D planetarium and astronomy software initially developed by Russian astronomer and programmer Vladimir Romanyuk. Development is now continued by Cosmographic Software, an American company founded by Romanyuk and the SpaceEngine Team in February 2022, based in Connecticut. SpaceEngine creates a 1:1 scale three-dimensional planetarium representing the entire observable universe, combining real astronomical data with scientifically accurate procedural generation algorithms. Users can travel through space in any direction or at any speed and can move forwards or backwards in time. SpaceEngine is currently in Software release life cycle#Beta, beta status. Up to version 0.9.8.0E, released in August 2017, it was available as freeware for Microsoft Windows. Version 0.990 beta, the first paid edition, was released on Steam (service), Steam in June 2019. The program fully supports VR headsets. Properties of objects, such as temperature, mass, radius, and spe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Nightshade (astronomy Software)
Nightshade is a simulation and visualization software for teaching and exploring astronomy, Earth science, and related topics. Its focus is on use in digital planetarium systems or as an educational tool, with additional features to allow it to also be used on desktop or laptop computers. It operates on Linux, macOS and Windows. Nightshade Legacy was open source and is no longer developed. A completely new codebase, Nightshade NG (Next Generation) is licensed under the "Nightshade Public License", a non-free license with field of use restrictions but with source available. History Nightshade Legacy began as a fork of Stellarium by Digitalis Education Solutions after controversy between the Stellarium project and its commercial contributor about a focus on desktop versus planetarium use. Development of Nightshade Legacy ceased around 2011. A rewrite, Nightshade NG, was begun in 2011, with a change to a non-free license with field of use restrictions to prevent its use by commer ...
