Planetary Science Research Discoveries (PSRD) is an educational site sharing the latest research by NASA-sponsored scientists on meteorites, asteroids, planets, moons, and other materials in our Solar System. The website is supported by the Cosmochemistry Program of NASA's Science Mission ...
Study of the origin, distribution, and destiny of life in the universe. These are interdisciplinary studies involving astronomers, astrophysicists, biologists, chemists, geneticists, geologists, paleontologists, planetary scientists, and specialists from other scientific fields. Three broad themes of astrobiology: Is there life elsewhere in the universe? How did life begin and evolve? What is the future for life on Earth and beyond?
Industry:Astronomy
The streak of light and loud noise of a large meteor passing through the Earth's atmosphere.
Industry:Astronomy
The study of the shape and form of the landscape, and how the nature of landforms relates to their origin, development, and change over time.
Industry:Astronomy
The energy given to an electron by accelerating it through 1 volt of electric potential difference.
Industry:Astronomy
A unit of energy equal to a thousand electron volts (eV). According to the Bureau International des Poids et Mesures: "The electron volt is the kinetic energy acquired by an electron in passing through a potential difference of one volt in vacuum. The electron volt is often combined with the SI prefixes. "
Industry:Astronomy
The acquisition of information on some property of a target object or material without being in physical contact with it. In the broadest terms, this is done by using instruments or scanners to sense and record reflected or emitted energy from the target and then processing the data in order to better analyze and understand the property in question.
Industry:Astronomy
The degree to which fine details in an image are separated or resolved.
Industry:Astronomy
Rocks or processes involving the formation and solidification of hot, molten magma.
Industry:Astronomy
Fine-grained, dark-colored extrusive igneous rock with less than about 52 weight percent silica (SiO<sub>2</sub>). Because of its low silica content, basalt has a low viscosity (resistance to flow. ) Basalt is composed primarily of plagioclase feldspar and pyroxene; other minerals such as olivine and ilmenite are usually present. Basalt is the most common volcanic rock on the terrestrial planets.
