June 24, 2014: In the lexicon of climate change, one word appears more often than any other: "carbon." Carbon credits, carbon emissions, carbon sequestration…. These terms are on everyone's lips. The reason is carbon dioxide (CO2).
Jun 23, 2014
NASA is about to launch a satellite dedicated to the study of the greenhouse gas carbon dioxide. The Orbiting Carbon Observatory (OCO-2) will quantify global CO2 sources and sinks, and help researchers predict the future of climate change.

June 10, 2014: Years ago, in 2008 and 2009 an eerie quiet descended on the sun. Sunspot counts dropped to historically-low levels and solar flares ceased altogether. As the longest and deepest solar minimum in a century unfolded, bored solar physicists wondered when "Solar Max" would ever... Read More

June 3, 2014: A spacecraft from Earth is about to do something no spacecraft has ever done before: orbit a comet and land on its surface.Right now, the European Space Agency's Rosetta probe is hurtling toward Comet 67P/Churyumov-Gerasimenko. The spacecraft's mission is to study the comet at close... Read More
