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 Stars form in large clouds of gas and dust called molecular clouds

Stars A star is a sphere of gas held together by its own gravity The closest star to Earth is our very own Sun, so we have an example nearby that astronomers can study in detail The lessons we learn about the Sun can be applied to other stars Tell me more about the Sun; A star's life is a constant struggle against the force of gravity

Stars are astronomical objects consisting of a luminous spheroid of plasma held together by their own gravity Stars are huge celestial bodies made mostly of hydrogen and helium that produce light and heat from the churning nuclear forges inside their cores Aside from our Sun, stars appear as dots of light in the sky
