Planetary Science Research Discoveries

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 Planetary Science Division 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.

» The Oldest Volcanic Meteorite: A Silica-Rich Lava on a Geologically Complex Planetesimal

(Posted August 10, 2018)

Link to article: The Oldest Volcanic Meteorite: A Silica-Rich Lava on a Geologically Complex Planetesimal. A volcanic meteorite is the oldest igneous meteorite identified so far, erupting onto its parent body only about 3 million years after the Solar System began to form.

6 RECENT HEADLINE ARTICLES.           [  V I E W     A L L  ]

» Minerals Track Chemical Reactions in Interstellar Space and in the Protoplanetary Disk
Mineral intergrowths in cosmic dust and primitive meteorites reveal processes that operated in interstellar space and in the protoplanetary disk surrounding the Sun before the planets formed.

» Meteorite Evidence for a Complicated Protoplanetary Disk
A striking dichotomy in isotopic compositions of meteorite groups appears to be consistent with Jupiter and Saturn migrating to and fro during planet formation.

» New Age for Lunar Exploration
A change in the National Space Policy adds a lunar emphasis to NASA exploration programs.

» Volcanism and an Ancient Atmosphere on the Moon
Extensive lunar volcanism around 3.5 billion years ago produced a temporary atmosphere on the Moon.

» Accretional Layers Preserved in a Meteorite
Visible sequence of layers in the Isheyevo meteorite tells a story of impact debris deposited, layer by layer, onto the surface of the surviving planetesimal.

» Meteorite Formation Times and the Age of Jupiter
Isotopic analyses of meteorites and models of planetary accretion indicate that Jupiter's solid core had accreted only one million years after the Solar System began to form.
