Stars and Galaxies
Stars and galaxies are the building blocks of the universe. A star is a massive, glowing sphere of gas, mostly made of hydrogen and helium, that produces energy through nuclear fusion. Stars come in different sizes, colors, and life cycles, from small red dwarfs to gigantic supernovae and black holes.
A galaxy is a vast collection of stars, gas, dust, and dark matter, bound together by gravity. Our home galaxy, the Milky Way, contains over 100 billion stars, including our Sun. The universe holds trillions of galaxies, each with unique shapes and properties.
ISRO, NASA, and other space agencies study stars and galaxies using powerful telescopes like Hubble, James Webb, and ISRO’s AstroSat, helping us uncover the mysteries of cosmic evolution and the fate of the universe
