Stars Of Pis Ahmedabad Std V Evs Notes Of Latitudes And Longitudes Many other stars are visible to the naked eye at night; 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. 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 Of Pis Ahmedabad Std Viii 8th व क य व च र Notes 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. Two factors result in so many different types of stars: the size of the clouds they are born from and what kinds of elements they contain. Stars are luminous spheres made of plasma – a superheated gas threaded with a magnetic field. they are made mostly of hydrogen, which stars fuse in their cores. that process releases energy, which pushes against the weight of the outer layers of the star and keeps it stable. How are stars named? and what happens when they die? these star facts explain the science of the night sky.

How are stars named? and what happens when they die? these star facts explain the science of the night sky. Stars are huge celestial bodies made mostly of hydrogen and helium that produce light and heat from the churning nuclear forges inside their cores.
