Stars are massive, luminous spheres of plasma held together by gravity, and they are the fundamental building blocks of galaxies. Formed from collapsing clouds of gas and dust, stars generate energy through nuclear fusion, converting hydrogen into helium and releasing light and heat in the process. They come in a wide range of sizes, colors, and life stages—from newborn protostars to red giants, white dwarfs, neutron stars, and black holes. Studying stars helps astronomers understand the origins of elements, the evolution of galaxies, and the dynamics of the universe itself. This page features the latest research and discoveries about stars, from stellar birth and death to their role in cosmic evolution.
