Astronomers working with NASA's Hubble Space Telescope have deduced the actual color of a planet orbiting another star 63 light-years away. The planet is HD 189733b, and its color is cobalt blue. If seen directly, this planet would look like a deep blue dot, reminiscent of Earth's color as seen from space.

A NASA-led team of scientists has uncovered strong evidence that soot from a rapidly industrializing Europe caused the abrupt retreat of mountain glaciers in the European Alps that began in the 1860s, a period often thought of as the end of the Little Ice Age.

Arctic permafrost soils contain more accumulated carbon than all the human fossil-fuel emissions since 1850 combined. Warming permafrost, poised to release its own gases into the atmosphere, could be the "sleeping giant" of climate change.
