Changing Sun, Changing Earth

iPhoto image of the sunHow and why does the Sun’s energy change, and how does the Earth respond? We care about these changes, and seek improved understanding of their causes and consequences. We do this because society urgently seeks to quantify anthropogenic and natural causes of climate change, because we are increasingly reliant on the technological benefits of space assets, and because we utilize and explore extensive environmental domains well beyond the surface where we live.

Panorama of the East Coast

Panorama of the East Coast

This Jan. 29 panorama of much of the East Coast, photographed by one of the Expedition 30 crew members aboard the International Space Station, provides a look generally northeastward: Philadelphia-New York City-Boston corridor (bottom-center); western Lake Ontario shoreline with Toronto (left edge); Montreal (near center). An optical illusion in the photo makes the atmospheric limb and light activity from Aurora Borealis appear "intertwined." Image Credit: NASA
