Glossary Germans

Anthropology: The social science that studies the origins and social relationships of human beings.
Astrochemistry, the overlap of the disciplines of astronomy and chemistry, is the study of the abundance and reactions of chemical elements and molecules in space, and their interaction with radiation. The word Astrochemistry can refer to both the Solar System, and the interstellar medium. One important aspect of astrochemistry is spectroscopy, the use of telescopes to measure the absorption and emission of light from molecules and atoms in various environments. By comparing astronomical observations with laboratory measurements scientists are able to infer the elemental abundances, chemical composition, and temperatures of stars and interstellar clouds.
Brownlee Particles: Is an interstellar dust localizated in the Earth's atmosphere and speculated that they may be the left over remnants of comets which passed through the Earth's orbit.
Buckyballs: A nano-structure consisted of 60 atoms of carbon (His chemical name is C60) constructed in a closed and perfectly symmetrical space, they have extraordinary properties, specially as superconductors. It is a new form of the carbon and has a geometry similar to an icosaedro, with the structure in the shape of a soccer ball. The surface of the image guesses the forms of buckyballs in his structure. The superconductive buckyballs show the highest critical temperature that one has found in organically compounds The mixture of poliuretano and the Buckyballs in a thin movie on a flat surface, the particles of light that travel across the material the bosses adopt with facility of other increasing the power of the transport and process of communications.

Paleontology: The earth science that studies fossil organisms and related remains.
Panspermia is the hypothesis that "seeds" of life exist already all over the Universe, that life on Earth may have originated through these "seeds", and that they may deliver or have delivered life to other habitable bodies. The related but distinct idea of exogenesis is a more limited hypothesis that proposes life on Earth was transferred from elsewhere in the Universe but makes no prediction about how widespread it is. Because the term "panspermia" is more well-known, it tends to be used in reference to what should strictly speaking be called exogenesis. Spores are a potential vector for transporting life through inhospitable and inimical environments, such as the depths of interstellar space. Spores are produced as part of the normal life cycle of many plants, algae, fungi and some protozoans, and some bacteria produce endospores or cysts during times of stress. These structures may be highly resilient while metabolically inactive, and some can function when favorable conditions are restored after exposure to radiation, temperature extremes, desiccation, or other conditions fatal to the parent organism.
Primordial Soup Theory: This theory suggest that life began in a pond or ocean as a result of the combination of chemicals from the atmosphere and some form of energy to make amino acids, the building blocks of proteins, which would then evolve into all the species.
Speciation: the evolution of a biological species.
Taxonomy: practice of classifying plants and animals according to their presumed natural relationships.
Vacuum: a region empty of matter or with absence of matter.
