 |  |  | Dust: Encyclopedia II - Dust - House dust
The dust which collects in houses is composed of atmospheric dust combined with dust generated by the inhabitants, mostly from sloughed skin cells and fibers from clothing and coverings. It can be removed with a broom, dusting cloth, or vacuum cleaner.
House dust mites, often found in fibers like carpets and beds, feed on the organic components of house dust. Their feces, in turn, become part of house dust and can pr ...

 |  |  | Dust: Encyclopedia II - Cosmic dust - Dust grain destructionHow are the interstellar grains destroyed? There are some ultraviolet processes which lead to grain "explosions" (d'Hendecourt et al., 1985; Greenberg, 1976). Evans (1994) also describes evaporation, sputtering (when an atom or ion strikes the surface of a solid with enough momentum to eject atoms from it), and grain-grain collisions, which have a major influence on the grain size distribution, as well.
These destructive processes happen in a variety of places. Some grains are destroyed in the supernovae/novae explosion (and then some ...

 |  |  | Dust: Encyclopedia II - Space dust - AnalysisThe dust that is collected is taken to a clean room. This room has filters to decrease the number of dust particles in the air. The room must have very few particles to avoid contaminating the samples. Space dust is then scanned by an electron microscope, after which the sample is sent to the NASA space dust library for storage. Currently, NASA can only catalog 300 particles a year.
The difference between dust from Earth and dust from space is easily observed. Dust from Earth almost never has Iridium or Osmium, and dust from space has ...

 |  |  | Dust: Encyclopedia II - Cosmic dust - Dust grain formationThe large grains start with the silicate particles forming in the atmospheres of cool stars, and carbon grains in the atmospheres of cool carbon stars. Stars, which have evolved off the main sequence, and which have entered the giant phase of their evolution, are a major source of dust grains in galaxies.
How do astronomers know that that dust is formed in the envelopes of late-evolved stars? They know from their observations. An observed (infrared) 9.7 micrometre emission silicate signature for cool evolved (oxygen-rich giant) stars. ...

Buddhist - Buddhism Dictionary on Dusts (Worldly Dusts) Dusts (Worldly Dusts) A metaphor for all the mundane things that can cloud our bright Self-Nature. These include form, sound, scent, taste, touch, dharmas (external opinions and views). These dusts correspond to the five senses and the discriminating, everyday mind (the sixth sense, in Buddhism).

 |  |  | Dust: Encyclopedia II - Cosmic dust - Some bulk properties of cosmic dustCosmic dust is dust grains and agreggates of dust grains. These particles are irregularly-shaped with porosity ranging from fluffy to compact. The composition, size, and other properties depends on where the dust is found. General diffuse interstellar medium dust should be distinguished from dust grains in dense clouds, which should be distinguished from planetary rings dust, which should be distinguished from circumstellar dust, and so on. For example, grains in dense clouds have acquired a mantle of ice and the average dimens ...

 |  |  | Dust: Encyclopedia II - Cosmic dust - Introductory MaterialCosmic Dust refers to particles in space which are assemblages of a few molecules to tenth-millimeter-sized grains. Cosmic dust can be further distinguished by its astronomical location; for example: interplanetary dust, interstellar dust, comet dust, circumplanetary dust. This article covers bulk and radiative properties of cosmic dust, the dust particles' origins, end-fates, and specific locations in space.
Historically, cosmic dust used to be an annoyance to astronomers because of the way that the dust obscures the object th ...
