1. Cosmic dust

   Cosmic dust, also called extraterrestrial dust, star dust or space dust, is dust which exists in outer space, or has fallen on Earth. Most cosmic dust particles measure between a few molecules and 0.1 mm (100 micrometers), such as micrometeoroids. Larger particles are called meteoroids. Cosmic dust can be further distinguished by its astronomical location: intergalactic dust, interstellar dust, interplanetary dust (such as in the zodiacal cloud) and circumplanetary dust (such as in a planetary ring). There are several methods to obtain space dust measurement. In the Solar System, interplanetary dust causes the zodiacal light. Solar System dust includes comet dust, planetary dust (like from Mars), asteroidal dust, dust from the Kuiper belt, and interstellar dust passing through the Solar System. Thousands of tons of cosmic dust are estimated to reach the Earth's surface every year, with most grains having a mass between 10−16 kg (0.1 pg) and 10−4 kg (0.1 g). The density of the dust cloud through which the Earth is traveling is approximately 10−6 dust grains/m3.Cosmic dust contains some complex organic compounds (amorphous organic solids with a mixed aromatic–aliphatic structure) that could be created naturally, and rapidly, by stars. A smaller fraction of dust in space is "stardust" consisting of larger refractory minerals that condensed as matter left by stars. Interstellar dust particles were collected by the Stardust spacecraft and samples were returned to Earth in 2006.

1. cosmic dust

   Cosmic dust, also known as interstellar dust or space dust, is extremely small solid particles in space, floating in between the stars. These particles are composed of various elements such as carbon, silicon, and oxygen, and they can range in size from a few molecules to about 0.1 µm. Cosmic dust is a key element in understanding many processes in space, including the formation of planets and stars, the production of molecules, and also the origin and evolution of galaxies.

1. Cosmic dust

   Cosmic dust can be taken to be all dust in the cosmos, as its name implies, or limited to space dust in our solar system, as scientists who study dust in the solar system prefer. It is for the most part a type of small dust particles which are a few molecules to 0.1 µm in size. A smaller fraction of all dust in space consists of larger refractory minerals that condensed as matter left the stars. It is called "stardust" and is included in a separate section below. Cosmic dust can be further distinguished by its astronomical location: intergalactic dust, interstellar dust, interplanetary dust and circumplanetary dust. In our own Solar System, interplanetary dust causes the zodiacal light. Sources of solar system dust include comet dust, asteroidal dust, dust from the Kuiper belt, and interstellar dust passing through our solar system. The terminology has no specific application for describing materials found on the planet Earth except for dust that has demonstrably fallen to earth. In October 2011, scientists reported that cosmic dust contains complex organic matter that could be created naturally, and rapidly, by stars.

1. Cosmic Dust

   Finely divided solid matter with particle sizes smaller than a micrometeorite, thus with diameters much smaller than a millimeter, moving in interplanetary space. (NASA Thesaurus, 1994)

Examples of cosmic dust in a Sentence

1. Albert Einstein, Dilip Kumar Roy, (famous Indian classical singer), had cited the above quotation of Einstein in one of his let:

   Let us not forget that knowledge and skills alone cannot lead humanity to a happy and dignified life. ... I claim credit for nothing. Everything is determined, the beginning as well as the end, forces over which we have no control. It is determined for the insects as well as for the stars, Human beings, vegetables or cosmic dust, we all dance to a mysterious tune, intoned in the distance by an invisible piper.
