Planetary scientists sharing ideas and discoveries.

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 Directorate and by Hawai'i Space Grant Consortium and is a vital link for planetary and space sciences, and for learning how science works.

25 JAN 07	Organic Globules from the Cold Far Reaches of the Proto-Solar Disk by G. Jeffrey Taylor Hollow organic globules in the Tagish Lake meteorite probably formed far from the proto-Sun, maybe even in interstellar space before our Solar System formed.
31 JAN 06	Cosmochemistry from Nanometers to Light-Years by G. Jeffrey Taylor Cosmochemists and astronomers test theories on the formation of stars and planets.
14 FEB 97	1997 Apparition of Comet Hale-Bopp by Karen J. Meech With its closest approach to Earth on March 22, 1997, comet Hale-Bopp gave a spectacular night time show. This article also covers the historical development of cometary science and the scientific importance of comets.
