TL;DR: The Stardust spacecraft collected thousands of particles from comet 81P/Wild 2 and returned them to Earth for laboratory study, and preliminary examination shows that the nonvolatile portion of the comet is an unequilibrated assortment of materials that have both presolar and solar system origin.

TL;DR: The asteroid impact near the Russian city of Chelyabinsk on 15 February 2013 was the largest airburst on Earth since the 1908 Tunguska event, causing a natural disaster in an area with a population exceeding one million.
Journal ArticleDOI
Biological control of terrestrial silica cycling and export fluxes to watersheds
TL;DR: Soil water in basaltic soils across the Hawaiian islands is analysed to assess the relative contributions of weathering and biogenic silica cycling by using the distinct signatures of the two processes in germanium/silicon ratios.

TL;DR: Hydrogen, carbon, nitrogen, and oxygen isotopic compositions are heterogeneous among comet 81P/Wild 2 particle fragments; however, extreme isotopic anomalies are rare, indicating that the comet is not a pristine aggregate of presolar materials.

TL;DR: In this article, the authors sampled 16 soil profiles along an arid to humid climosequence on Kohala Mountain, Hawaii, and found that weathering and soil properties change in a nonlinear fashion with increased rainfall.
