Cosmic dust

Cosmic dust is dust which exists in space. Most cosmic dust particles are between 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. The dust density in the local interstellar medium of the Local Bubble is approximately 10−6 × dust grain/m3 with each grain having a mass of approximately 10−17 kg.

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). In the 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 the 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. By one estimate, as much as 40,000 tons of cosmic dust reaches the Earth's surface every year. In October 2011, scientists reported that cosmic dust contains complex organic matter ("amorphous organic solids with a mixed aromaticaliphatic structure") that could be created naturally, and rapidly, by stars.

  • Pop Rocks

    Pop Rocks is a carbonated candy with ingredients including sugar, lactose (milk sugar), corn syrup, and flavoring. It differs from typical hard candy in that it creates a fizzy reaction when it dissolves in one's mouth.

    Background and history

    The concept was patented by General Foods research chemist William A. Mitchell in 1957. The candy was first offered to the public in 1975. In 1983, General Foods withdrew the product owing to its lack of success in the marketplace and to its relatively short shelf life.

    Distribution was initially controlled to ensure freshness; but with its increasing popularity, unauthorized redistribution from market to market resulted in out-of-date product reaching consumers. After that, Kraft Foods licensed the Pop Rocks brand to Zeta Especial S.A. who continued manufacturing the product under Kraft's license. Eventually Zeta Especial S.A. became the brand's owner and sole manufacturer. Pop Rocks is distributed in the U.S. by Pop Rocks Inc. (Atlanta, Georgia) and by Zeta Especial S.A. (Barcelona, Spain) in the rest of the world. Zeta Especial S.A. also sells popping candy internationally under other brands including Peta Zetas, Fizz Wiz and Magic Gum.
