cosmic dust

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.

Porous chondrite dust particle

Cosmic dust – also called extraterrestrial dust, space dust, or star dust – is dust that occurs in outer space or has fallen onto Earth. Most cosmic dust particles measure between a few molecules and 0.1 mm (100 μm), such as micrometeoroids (<30 μm) and meteoroids (>30 μm). Cosmic dust can be further distinguished by its astronomical location: intergalactic dust, interstellar dust, interplanetary dust (as in the zodiacal cloud), and circumplanetary dust (as in a planetary ring). Information on the nature of dust in locations beyond the Solar System is mostly obtained by methods of observational astronomy, such as photometry, polarimetry and infrared spectroscopy. Direct methods are also available for the collection and study of space dust within the Solar System. For example, the Stardust spacecraft collected cometary dust, and also detected some particles of probable interstellar origin, returning samples to Earth in 2006.
