Explaining The Universe on Instagram: "Comets are icy celestial bodies that orbit the Sun, often described as “dirty snowballs” made of rock, dust, frozen gases, and organic materials. When a comet travels close to the Sun, heat causes its ice to vaporize, releasing gas and dust that form a glowing coma (a cloud around the nucleus) and a long tail that always points away from the Sun due to the solar wind. • #explore #reels #viral #universe #explaining #space"
