The Hilda asteroids (or “asteroids”) form a fringe around the outside of the Main Belt. A resonant structure formed by Jupiter’s gravity, they are not a complete ring. Being at the very edge of the Belt, they are prime candidates for water ice and other volatiles. Every so often, a Hilda object may suffer from meteor impact, YORP spinup, etc., exposing subsurface volatiles and initiating activity. García-Migani et al. search for that activity (and therefore volatiles).
From the present, to the start- the very start. CAIs (Calcium Aluminum rich Inclusions) are, by definition, the first solids in the Solar System- they define the start point of our history. Fukai et al. put more decimal places on CAIs from Allende, arguably the most studied single rock, and whose fall marked a new era in meteoritics and cosmochemistry.
