PLANETARY SCIENCE![Figure][1] Curdled rings. Clumping hid the rings' mass and possibly their antiquity. CREDIT: NASA/JPL/UNIVERSITY OF COLORADO SAN FRANCISCO, CALIFORNIA— Saturn's rings, like any aging beauty, are keeping their age mysterious. Before the first spacecraft reached Saturn, planetary scientists assumed its rings formed along with the planet 4.5 billion years ago. But the Voyager spacecraft flying by in the early 1980s sent back evidence that the rings could be just a few… Expand
Searching for the near-infrared counterpart of Proxima c using multi-epoch high-contrast SPHERE data at VLT
Context. Proxima Centauri is the closest star to the Sun and it is known to host an Earth-like planet in its habitable zone; very recently a second candidate planet was proposed based on radialExpand
Science Instruments and Experiments
The Hale Telescope has an adaptive optics system that uses a small deformable mirror to “un-twinkle” the objects it observes through the turbulent air, the better to learn about their nature. Expand
Commoditization seems immutable and unstoppable but, like other social processes, its prevalence is context dependent. The enabling context for commoditization has been cheap fossil fuels, economicExpand
Sustainability and consumption
We consider the implications of the three pillars of sustainability (environment, economy and social justice) on consumption in a wealthy country. Building a theoretical model that includesExpand
