Stars

Star Stars Star Stars Astronomers call stars that are stably undergoing nuclear fusion of hydrogen into helium main sequence star s. this is the longest phase of a star’s life. the star’s luminosity, size, and temperature will slowly change over millions or billions of years during this phase. our sun is roughly midway through its main sequence stage. A star is a luminous sphere of plasma held together by self gravity. learn about the origin, evolution, properties and classification of stars, as well as their cultural and scientific significance throughout history. Learn everything you wanted to know about stars, from their birth and death to their color and brightness. discover how stars help us navigate the sky and the universe, and see stunning photos of nebulae and constellations. Types of stars. image credit: nasa. a star’s color relies on its temperature: hotter stars emit bluer light and cooler stars emit redder light. temperature is also correlated to mass. red dwarf stars have as little as 0.075 solar masses and a visible surface temperature less than 4,000 k. the most massive star known is r136a1, a wolf rayet.

Stars range in size from neutron stars, which can be only 12 miles (20 kilometers) wide, to supergiants roughly 1,000 times the diameter of the sun. the size of a star affects its brightness. Learn about the formation, types, lifecycle, and death of stars, the luminous spheres made of plasma that are the main components of galaxies. find out how many stars are visible to the naked eye, how old the sun is, and which stars are the brightest and most massive.
