Stars are not spread uniformly across the universe but are normally grouped into galaxies along with interstellar gas and dust A typical large galaxy like the Milky Way contains hundreds of billions of stars There are more than 2 trillion 10 12 galaxies though most are less than 10 the mass of the Milky Way Stars are giant balls of hot gas mostly hydrogen with some helium and small amounts of other elements Every star has its own life cycle ranging from a few million to trillions of years and its properties change as it ages

Everything you wanted to know about stars These luminous balls of gas helped ancient explorers navigate the seas and now help modern day scientists navigate the universe Star any massive self luminous celestial body of gas that shines by radiation derived from its internal energy sources Of the tens of billions of trillions of stars composing the observable universe only a very small percentage are visible to the naked eye Many stars occur in pairs multiple systems or star clusters
A star is born Scientists call a star that is fusing hydrogen to helium in its core a main sequence star Main sequence stars make up around 90 of the universe s stellar population They range in luminosity color and size from a tenth to 200 times the Sun s mass and live for millions to billions of years A star is a luminous ball of gas mostly hydrogen and helium held together by its own gravity Nuclear fusion reactions in its core support the star against gravity and produce photons and heat as well as small amounts of heavier elements The Sun is the closest star to Earth

How are stars named And what happens when they die These star facts explain the science of the night sky All stars are born in clouds of dust and gas like the Pillars of Creation in the Eagle Nebula pictured below In these stellar nurseries clumps of gas form pulling in more and more mass as time passes As they grow these clumps start to spin and heat up Once they get heavy and hot enough like 27 million degrees Fahrenheit or 15 million degrees
