宇宙塵

Also known as star dust, space dust

dust floating in space

AI overview

Cosmic dust is tiny particles of material floating throughout space, often created from stars and galaxies. It matters because it plays a role in forming new stars and planets, and it affects how we observe the universe.

宇宙塵（英語：Cosmic Dust）是由眾多細小粒子組成的一種固態塵埃，自宇宙大爆炸起，便四散在浩瀚宇宙之中。宇宙塵的組成包含矽酸鹽、碳等元素以及水分，部分來自彗星、小行星等星體的崩解而產生。宇宙塵對一個天體的誕生亦有影響，例如一個星體崩壞後所產生的宇宙塵，在經過漫長的宇宙旅程後，可能與一個正在形成的星體撞上，於是又循環成為了一個新的星體。在太陽系中，木星、土星、天王星、海王星等行星的光環，即是由於在行星初形成時，碎裂的宇宙塵未能融為星球的主體，但卻又無法擺脫行星萬有引力的牽制而產生圍繞著星球的破碎物質。
