Space Dust

Space dust consists of tiny particles, often less than a few micrometers across, that float in space between stars and planets. These particles originate from various sources such as comets, asteroids, and the remnants of supernovae. Although individually minuscule, collectively they play a significant role in cosmic processes, like helping form new stars and planets. Space dust can absorb and scatter light, affecting astronomical observations. It also interacts with space weather and can pose a hazard to spacecraft. Despite their small size, space dust particles are fundamental components of the universe's matter cycle.
