Fundamental Space Science Concepts 

Astronomers are very interested in how stars evolve, to help us better understand how our own Sun and other stars formed and how they will end, and how this cycle of change generates the elements and molecules that make up the planets, oceans, life, and us. Stars come in different sizes and colors (red, orange, yellow, white, and blue) and change over time.

Stars are born in dense clouds of gas and dust in space, which are difficult to see inside. Telescopes like the James Webb Space Telescope will be able to peer into those clouds, to study the forming stars and planets. These clouds   form thousands of stars in clusters like the Pleiades. For most of their billions of years stars change slowly as they consume their hydrogen fuel in their cores. As a star ages, its core becomes denser and hotter, and the outer envelope of gas becomes more diffuse and broader—it grows and becomes a red giant. If it is very massive, it will continue to expand into a red supergiant. At the end of their “lives,” a small or medium-mass star (like our Sun) will shed its outer layers of gas, leaving its hot dense core (a white dwarf) behind . A massive star will become unstable and explode in a supernova while its remaining core collapses into a neutron star or black hole.
