Its total mass mainly determines its evolution and eventual fate. A star shines for most of its active life due to the thermonuclear fusion of hydrogen into helium in its core. This process releases energy that A star’s gas provides its fuel, and its mass determines how rapidly it runs through its supply, with lower-mass stars burning longer, dimmer, and cooler than very massive stars. Star, any massive self-luminous celestial body of gas that shines by radiation derived from its internal energy sources. This article describes the properties and evolution of individual stars. This article takes you deep into the heart of stellar science — from the birth of a star in vast clouds of gas and dust, to its dramatic demise as a white dwarf, neutron star, or black hole. A star that consumes hydrogen to form helium is called a "main-sequence" star for all the time it is a hydrogen-fusing object. When it uses up all its fuel, the core contracts because the

In this artist’s rendition, the newly discovered planet is shown as a hot, rocky, geologically-active world glowing in the deep red light of its nearby parent star, the M dwarf Gliese 876.
