Dust and Gas

Dust and gas are the fundamental building blocks of the universe. Gas consists of particles like atoms and molecules that move freely, forming clouds such as those in nebulae. Dust is made up of tiny solid particles, including bits of minerals, metals, and organic materials, and appears as fine, dark patches against brighter backgrounds. While gas forms the bulk of stars and planetary atmospheres, dust plays a critical role in cooling cosmic regions, aiding star formation, and creating the intricate patterns seen in space. Together, they shape the structure and evolution of galaxies, stars, and planets.
