In the early hours of Feb. 8, 1969, a large fireball rumbled out of the southwest, and exploded, sending thousands of stones over a nearly 200-square-mile (300 km) area - the most important stony meteorite shower on record. The Allende meteorite, as it came to be called, is a rare type of meteorite and turned out to contain some of the oldest matter known in our planetary system. Studying it has opened new windows on the formation of the early solar system. #seriouslyamazing

The search for life beyond our solar system requires cooperation across scientific disciplines — the way the UW-based Virtual Planetary Laboratory has been working since 2001. Now, NASA’s NExSS collaboration will take a similarly interdisciplinary approach to the search for life. Participants include those who study Earth as a life-bearing planet (lower right), those researching the diversity of solar system planets (left), and those on the new frontier, discovering worlds orbiting other…
