Enceladus Flyby – July 14, 2005
On July 14, the Cassini spacecraft conducted its closest flyby yet, coming within 175 kilometers (109 miles) from the surface of the wrinkled, icy moon, Enceladus. During Cassini’s first flyby of Enceladus, a tenuous atmosphere was detected in magnetic field…
Glaciers, Climate Change, and Sea-Level Rise
Average global sea level rises and falls in response to climate change. When global surface temperatures are low, more snow and ice accumulate on land, and sea level drops. A warmer climate increases melting of glaciers and ice sheets, and…

Carlsbad Caverns, New Mexico
In southeastern New Mexico, an ancient and unusual coral reef rises thousands of feet above the surrounding desert terrain. The fossilized reef is etched with caves, and it is hundreds of millions of years old. It formed in the Permian…
