NASA’s Cassini spacecraft captured the color images of Earth and the moon from its perch in the Saturn system nearly 900 million miles (1.5 billion kilometers) away. MESSENGER, the first probe to orbit Mercury, took a black-and-white image from a distance of 61 million miles (98 million kilometers) as part of a campaign to search […]

Global Warming Proof
by the Institute for Marine and Antarctic Studies Ocean measurements taken more than 135 years ago during the scientific expedition of HMS Challenger have provided further confirmation of human-produced global warming over the past century. The researchers also found the thermal expansion of sea water caused by this global warming contributed to around 40 per […]
Severe Weather Events: Tornadoes
Because a tornado is part of a severe convective storm, and these storms occur all over the Earth, tornadoes are not limited to any specific geographic location. In fact, tornadoes have been documented in every state of the United States, and on every continent, with the exception of Antarctica (even there, a tornado occurrence is […]

The new study builds upon a previous USGS snowpack investigation which showed that, until the 1980s, the northern Rocky Mountains […]
Coastal Change: Hurricanes and Extreme Storm Hazards
Part of the Human Induced Climate Change Experiment One of the goals of the USGS Coastal and Marine Geology Program is a national assessment of coastal change hazards. Hurricanes provide a powerful force that generates dangerous waves and currents capable of moving large amounts of sand, destroying buildings and infrastructure, and reshaping our nation’s coastline.

Noise Pollution
We’re so use to it that a lot of us hardly notice the noise that surrounds us everyday, but our hearts may be picking up the buzz. Researchers in Germany had more than 100 people record their heart activity over several 6-hour spans. They also recorded surrounding noise levels. The sounds were classified as either […]
