Getting to know Rosetta's comet
ESA
Rosetta is revealing its host comet as having a remarkable array of surface features and with many processes contributing to its activity, painting a complex picture of its evolution. In a special edition of the journal Science, initial results are presented from seven of Rosetta's 11 science instruments based on measurements made during the approach to and soon after arriving at Comet 67P/Churyumov–Gerasimenko in August 2014.

Melting glaciers have big carbon impact, study shows
Florida State University
As the Earth warms and glaciers all over the world begin to melt, researchers and public policy experts have focused largely on how all of that extra water will contribute to sea level rise. But another impact lurking in that inevitable scenario is carbon. More specifically, what happens to all of the organic carbon found in those glaciers when they melt? That's the focus of a new paper by a research team that includes Florida State University assistant professor Robert Spencer.
