Cosmic dust consists of tiny particles of solid material floating around in the space between the stars. It is primarily composed of elements that are abundant in the universe, such as:
- Carbon
- Oxygen
- Iron
- Silicon
- Magnesium
- Nitrogen
These particles can be characterized as soot-like (rich in carbon) or sand-like (containing silicon and oxygen) . The dust particles are about the same size as the wavelength of light and consist of rocky cores. Cosmic dust is important because it is found around young stars, helps them form, and serves as the raw material from which planets like Earth are formed. In addition to these elements, cosmic dust also contains complex organic compounds and larger refractory minerals that condensed as matter left by stars.
