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 ...
Gamma rays are like the light we see with our eyes, the x-rays used to probe our bodies in search of problems, and the radio waves that our television sets translate into inane shows. The only difference among these types of electromagnetic radiation is the wavelengths of the waves and how fast they vibrate. Gamma rays are the most energetic (and vibrate the most); radio waves are the least energetic and vibrate the least.
Industry:Astronomy
Meteorites that have been identified through their chemistry and minerals as being from the Moon. (See Lunar Meteorites compiled by Randy Korotev from Washington University, St. Louis. )
Industry:Astronomy
A region of exceptional brightness in an atmospheric layer of the Sun, often associated with sunspots of complex magnetic fields.
Industry:Astronomy
Bodies ranging in size from meters up to hundreds of kilometers in diameter that formed during the process that formed the planets by accretion. Most planetesimals accreted to form the planets.
Industry:Astronomy
Igneous rock found in the lunar highlands composed of plagioclase and pyroxene.
Industry:Astronomy
A condition where the solar elongation is zero, or practically speaking, so small that the celestial object cannot be seen in the glare of the Sun.
Industry:Astronomy
A rare class of red giant stars unusually rich in carbon or carbon compounds.
Industry:Astronomy
Long channel on the Moon crossing the surface of maria; probably formed either as an open channel in a lava flow, or as an under-ground tube carrying hot lava which collapsed as the lava flowed out.
Industry:Astronomy
A powerful compressional wave that lasts for an extremely brief time. Shock waves are created by explosive events, such as the impact of a meteorite on a planetary surface.
