Stardust grains are solid refractory pieces of individual presolar stars. They are recognized by their extreme isotopic compositions, which can only be isotopic compositions within evolved stars, prior to any mixing with the interstellar medium. These grains condensed from the stellar matter as it cooled while … See more 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 See more A wide range of methods is available to study cosmic dust. Cosmic dust can be detected by remote sensing methods that utilize the radiative properties of cosmic dust particles, c.f. See more A dust particle interacts with electromagnetic radiation in a way that depends on its cross section, the wavelength of the electromagnetic radiation, and on the nature of the grain: its refractive index, size, etc. The radiation process for an … See more Cosmic dust is made of dust grains and aggregates into dust particles. These particles are irregularly shaped, with porosity ranging … See more Cosmic dust was once solely an annoyance to astronomers, as it obscures objects they wished to observe. When infrared astronomy began, the dust particles were … See more Stardust grains (also called presolar grains by meteoriticists ) are contained within meteorites, from which they are extracted in terrestrial laboratories. Stardust was a component of the dust in the interstellar medium before its incorporation into meteorites.

WebAug 19, 2024 · A new analysis of samples of asteroid Ryugu has revealed the presence of mineral grains forged in the outflows or explosions of old stars before our own Sun formed. As identified by previous research, these presolar grains reveal Ryugu is very similar to a class of meteorites known as Ivuna-type carbonaceous (CI) chondrites.
