Cosmic dust was once solely an annoyance to astronomers, as it obscures objects they wished to observe.
| FactSnippet No. 1,206,857 |
When infrared astronomy began, the Cosmic dust particles were observed to be significant and vital components of astrophysical processes.
| FactSnippet No. 1,206,858 |
For example, cosmic dust can drive the mass loss when a star is nearing the end of its life, play a part in the early stages of star formation, and form planets.

Interdisciplinary study of Cosmic dust brings together different scientific fields: physics, fractal mathematics, surface chemistry on Cosmic dust grains, meteoritics, as well as every branch of astronomy and astrophysics.

Cosmic dust can be detected by indirect methods that utilize the radioactive properties of the cosmic dust particles that are very dangerous.
| FactSnippet No. 1,206,861 |
Cosmic dust can be detected directly using a variety of collection methods and from a variety of collection locations.

Infrared light can penetrate cosmic dust clouds, allowing us to peer into regions of star formation and the centers of galaxies.

StarCosmic dust grains are contained within meteorites, from which they are extracted in terrestrial laboratories.
| FactSnippet No. 1,206,866 |
StarCosmic dust was a component of the Cosmic dust in the interstellar medium before its incorporation into meteorites.
| FactSnippet No. 1,206,867 |
StarCosmic dust is a scientific term referring to refractory Cosmic dust grains that condensed from cooling ejected gases from individual presolar stars and incorporated into the cloud from which the Solar System condensed.
| FactSnippet No. 1,206,868 |
Many different types of starCosmic dust have been identified by laboratory measurements of the highly unusual isotopic composition of the chemical elements that comprise each starCosmic dust grain.
| FactSnippet No. 1,206,869 |
An important property of starCosmic dust is the hard, refractory, high-temperature nature of the grains.
| FactSnippet No. 1,206,870 |
The high interest in starCosmic dust derives from new information that it has brought to the sciences of stellar evolution and nucleosynthesis.
| FactSnippet No. 1,206,871 |
Cosmic dust is made of dust grains and aggregates into dust particles.
| FactSnippet No. 1,206,872 |
Cometary Cosmic dust resembles interstellar grains which can include silicates, polycyclic aromatic hydrocarbons, and water ice.
| FactSnippet No. 1,206,873 |
Those refractory cores are called stardust, which is a scientific term for the small fraction of cosmic dust that condensed thermally within stellar gases as they were ejected from the stars.
| FactSnippet No. 1,206,874 |
Meteoriticists who study refractory starCosmic dust often call it presolar grains but that within meteorites is only a small fraction of all presolar Cosmic dust.
| FactSnippet No. 1,206,875 |
Finally, as the Solar System formed many interstellar Cosmic dust grains were further modified by coalescence and chemical reactions in the planetary accretion disk.
| FactSnippet No. 1,206,876 |
The provenance of the small fraction that is starCosmic dust is quite different; these refractory interstellar minerals thermally condense within stars, become a small component of interstellar matter, and therefore remain in the presolar planetary disk.

Some larger Cosmic dust catalogs are Sharpless A Catalogue of HII Regions, Lynds Catalogue of Bright Nebulae, Lynds Catalogue of Dark Nebulae, van den Bergh Catalogue of Reflection Nebulae, Green Rev Reference Cat.
