Space Dust

Pop Rocks

Pop Rocks, also known as popping candy, is a type of candy owned by Zeta Espacial S.A. It differs from typical hard candy in that pressurized carbon dioxide gas bubbles are embedded inside of the candy, creating a small popping reaction when it dissolves. Pop Rocks additionally consists of sugar, lactose, and flavoring.

Cosmic dust

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 (100 μm), such as micrometeoroids and meteoroids. Cosmic dust can be further distinguished by its astronomical location: intergalactic dust, interstellar dust, interplanetary dust, and circumplanetary dust. Information on the nature of dust in locations beyond the Solar System is mostly obtained by methods of observational astronomy, such as photometry, polarimetry and infrared spectroscopy. Direct methods are also available for the collection and study of space dust within the Solar System. For example, the Stardust spacecraft collected cometary dust, and also detected some particles of probable interstellar origin, returning samples to Earth in 2006.

Space

Space is a three-dimensional continuum containing positions and directions. In classical physics, physical space is often conceived in three linear dimensions. Modern physicists usually consider it, with time, to be part of a boundless four-dimensional continuum known as spacetime. The concept of space is considered to be of fundamental importance to an understanding of the physical universe. However, disagreement continues between philosophers over whether it is itself an entity, a relationship between entities, or part of a conceptual framework.

Dust

Dust is made of fine particles of solid matter. On Earth, it generally consists of particles in the atmosphere that come from various sources such as soil lifted by wind, volcanic eruptions, and pollution.

space dust

Noun

1. Synonym of cosmic dust.
2. A part of a spaceship or oscillator that appears to consist of a random mixture of alive and dead cells, usually making it very difficult for a glider synthesis to be found for the object.
