By convention, astronomers grouped prominent stars into asterisms and constellations and used them to track the motions of the planets and the inferred position of the Sun. Many ancient astronomers believed that the stars were permanently affixed to a heavenly sphere and that they were immutable. They have been part of religious practices, used for celestial navigation and orientation, to mark the passage of seasons, and to define calendars.Įarly astronomers recognized a difference between " fixed stars", whose position on the celestial sphere does not change, and "wandering stars" ( planets), which move noticeably relative to the fixed stars over days or weeks. Historically, stars have been important to civilizations throughout the world. This 1690 depiction of the constellation of Leo, the lion, is by Johannes Hevelius. People have interpreted patterns and images in the stars since ancient times. Star is cognate (shares the same root) with the following words: asterisk, asteroid, astral, constellation, Esther. Some scholars believe the word is a borrowing from Akkadian "istar" (venus), however some doubt that suggestion. Compare Latin stella, Greek aster, German Stern. The word "star" ultimately derives from the Proto-Indo-European root "h₂stḗr" also meaning star, but further analyzable as h₂eh₁s- ("to burn", also the source of the word "ash") + -tēr (agentive suffix). Stars can form part of a much larger gravitationally bound structure, such as a star cluster or a galaxy. When two such stars have a relatively close orbit, their gravitational interaction can have a significant impact on their evolution. Stars can form orbital systems with other astronomical objects, as in the case of planetary systems and star systems with two or more stars. Astronomers can determine stellar properties including mass, age, metallicity (chemical composition), variability, distance, and motion through space by carrying out observations of a star's apparent brightness, spectrum, and changes in its position on the sky over time. Chemically enriched material is returned to the interstellar medium by stellar mass loss or supernova explosions and then recycled into new stars. At the end of a star's lifetime, its core becomes a stellar remnant: a white dwarf, a neutron star, or, if it is sufficiently massive, a black hole.Īlmost all naturally occurring elements heavier than lithium are created by stellar nucleosynthesis in stars or their remnants. For most of its active life, a star shines due to thermonuclear fusion of hydrogen into helium in its core, releasing energy that traverses the star's interior and then radiates into outer space. The total mass of a star is the main factor that determines its evolution and eventual fate. The observable universe contains an estimated 10 22 to 10 24 stars, but most are invisible to the naked eye from Earth, including all individual stars outside our galaxy, the Milky Way.Ī star's life begins with the gravitational collapse of a gaseous nebula of material composed primarily of hydrogen, along with helium and trace amounts of heavier elements. Astronomers have assembled star catalogues that identify the known stars and provide standardized stellar designations. The most prominent stars are grouped into constellations and asterisms, and many of the brightest stars have proper names. Many other stars are visible to the naked eye at night, but due to their immense distance from Earth they appear as fixed points of light in the sky. Lines have been added.Ī star is an astronomical object consisting of a luminous spheroid of plasma held together by its own gravity.

#Star citizen spectrum series
The Spectrum Dispatch series focus on lore, and specifically samples of things you might find published to media (referred to as the Spectrum) in the game's lore. Official communications from CIG, referred to as Comm-Links.
