Stars form in large clouds of gas and dust called molecular clouds. Like planets, stars accrete sufficient mass to assume a spherical shape, held together by their own gravity Many other stars are visible to the naked eye at night
Stars | Facts, Information, History & Definition
Their immense distances from earth make them appear as fixed points of light
The most prominent stars have been categorised into constellations and asterisms, and many of the brightest stars have proper names.
This article describes the properties and evolution of individual stars Included in the discussion are the sizes, energetics, temperatures, masses, and chemical compositions of stars. Stars are a fundamental component in the universe and collectively form star clusters, galaxies and galaxy clusters Find out more about star names, star clusters to see with the naked eye, how to photograph stars and the science of stardust.
Stars are huge celestial bodies made mostly of hydrogen and helium that produce light and heat from the churning nuclear forges inside their cores. Stars are spherical balls of hot, ionized gas (plasma) held together by their own gravity Stars are the most fundamental building blocks of our universe. Stars are massive, luminous spheres of gas, mainly composed of hydrogen, with smaller amounts of helium and other elements
The lifespan of a star varies widely, generally ranging from several million to several trillion years.
Stars are huge balls of hot, glowing gas that make light and heat through fusion Stars come in different sizes and colors, and each one has a life cycle like our sun As stars die, they spread elements in space that help make new stars, planets, and life. A star is a huge sphere of very hot, glowing gas
Stars produce their own light and energy by a process called nuclear fusion Fusion happens when lighter elements are forced to become heavier elements When this happens, a tremendous amount of energy is created causing the star to heat up and shine Stars come in a variety of sizes and colors.
The sun is a star
Stars form from clouds of dust and gas
