The timeline of the early universe outlines the formation and subsequent evolution of the Universe from the Big Bang to the present day. An epoch is a moment in time from which nature or situations change to such a degree that it marks the beginning of a new era or age.
Planetesimals are solid objects thought to exist in protoplanetary disks and debris disks. Believed to have formed in the Solar System about 4.6 billion years ago, they aid study of its formation.
An astronomical object, celestial object, stellar object or heavenly body is a naturally occurring physical entity, association, or structure that exists within the observable universe. In astronomy, the terms object and body are often used interchangeably. However, an astronomical body or celestial body is a single, tightly bound, contiguous entity, while an astronomical or celestial object is a complex, less cohesively bound structure, which may consist of multiple bodies or even other objects with substructures.
The interstellar space opera epic Star Wars uses science and technology in its settings and storylines. The series has showcased many technological concepts, both in the movies and in the expanded universe of novels, comics and other forms of media. The Star Wars movies' primary objective is to build upon drama, philosophy, political science and less on scientific knowledge. Many of the on-screen technologies created or borrowed for the Star Wars universe were used mainly as plot devices.
Celestia is a real-time 3D astronomy software program that was created in 2001 by Chris Laurel. The program allows users to virtually travel through the universe and explore celestial objects that have been catalogued. Celestia also doubles as a planetarium, but the user is not restricted to the Earth's surface, like in other planetarium software such as Stellarium. Celestia can display objects of various scales using OpenGL.
Orbiter is a space flight simulator program developed to simulate spaceflight using realistic Newtonian physics. The simulator was released on 27 November 2000; the latest edition, labeled "Orbiter 2016", was released on 30 August 2016, the first new version of the simulator since 2010. On 27 July 2021, Dr Schweiger announced to the Orbiter Community that Orbiter is being published under open source MIT license.
In astrophysics, accretion is the accumulation of particles into a massive object by gravitationally attracting more matter, typically gaseous matter, into an accretion disk. Most astronomical objects, such as galaxies, stars, and planets, are formed by accretion processes.
Sins of a Solar Empire is a 2008 science fiction real-time strategy video game developed by Ironclad Games and published by Stardock Entertainment for Microsoft Windows operating systems. It is a real-time strategy (RTS) game that incorporates some elements from 4X games; its makers describe it as "RT4X". Players are given control of a spacefaring empire in the distant future, and are tasked with conquering star systems using military, economic and diplomatic means.
There is evidence that the formation of the Solar System began about 4.6 billion years ago with the gravitational collapse of a small part of a giant molecular cloud. Most of the collapsing mass collected in the center, forming the Sun, while the rest flattened into a protoplanetary disk out of which the planets, moons, asteroids, and other small Solar System bodies formed.
WorldWide Telescope (WWT) is an open-source set of applications, data and cloud services, originally created by Microsoft Research but now an open source project hosted on GitHub. The .NET Foundation holds the copyright and the project is managed by the American Astronomical Society and has been supported by grants from the Moore Foundation and National Science Foundation. WWT displays astronomical, earth and planetary data allowing visual navigation through the 3-dimensional (3D) Universe. Users are able to navigate the sky by panning and zooming, or explore the 3D universe from the surface of Earth to past the Cosmic microwave background (CMB), viewing both visual imagery and scientific data about that area and the objects in it. Data is curated from hundreds of different data sources, but its open data nature allows users to explore any third party data that conforms to a WWT supported format. With the rich source of multi-spectral all-sky images it is possible to view the sky in many wavelengths of light. The software utilizes Microsoft's Visual Experience Engine technologies to function. WWT can also be used to visualize arbitrary or abstract data sets and time series data.
A space flight simulation is a genre of flight simulator video games that lets players experience space flight to varying degrees of realism. Common mechanics include space exploration, space trade and space combat.
Retrograde motion in astronomy is, in general, orbital or rotational motion of an object in the direction opposite the rotation of its primary, that is, the central object. It may also describe other motions such as precession or nutation of an object's rotational axis. Prograde or direct motion is more normal motion in the same direction as the primary rotates. However, "retrograde" and "prograde" can also refer to an object other than the primary if so described. The direction of rotation is determined by an inertial frame of reference, such as distant fixed stars.
Kerbal Space Program (KSP) is a space flight simulation video game developed by Mexican studio Squad for Linux, macOS, Windows, PlayStation 4, PlayStation 5, Xbox Series X/S and Xbox One. In the game, players direct the space program of a species of green humanoid aliens known as "Kerbals". The game features a pseudorealistic orbital physics engine, allowing for various real-life orbital maneuvers such as Hohmann transfer orbits and orbital rendezvous.
This glossary of astronomy is a list of definitions of terms and concepts relevant to astronomy and cosmology, their sub-disciplines, and related fields. Astronomy is concerned with the study of celestial objects and phenomena that originate outside the atmosphere of Earth. The field of astronomy features an extensive vocabulary and a significant amount of jargon.
Keen Software House is an independent video game developing company based in Prague, Czech Republic. The company was founded by Marek Rosa in 2010.
Space Engineers is a voxel-based sandbox game, developed and published by Czech independent developer Keen Software House. In 2013, the initial developmental release of the game joined the Steam early access program. During the following years of active development, Space Engineers sold over one million units. In total as of 2019 the game has sold over 3.5 million copies In May 2015, for approximately a year and a half, the game's source code was officially available and maintained by KSH to assist the modding community. On December 15, 2016, the game entered Beta and was later officially released on February 28, 2019.
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.
Solar 2 is an open world sandbox video game developed by Australian developer Jay Watts' video game studio, Murudai. It was released on 17 June 2011 on Steam for Microsoft Windows and on 19 June 2011 on Xbox Live Indie Games for the Xbox 360. The game was developed with Microsoft's XNA tools, and its development was inspired by indie games such as flOw. The game follows the player in their mission to accumulate enough mass to become several astronomical objects, eventually becoming a Big Crunch, which then produces a Big Bang.
The following outline is provided as an overview of and topical guide to Jupiter:
