Provided by Eric Sorensen, Washington State University A Washington State University undergraduate has helped develop a new method for detecting water on Mars. Her findings appear in Nature Communications, one of the most influential general science journals. Kellie Wall, 21, of Port Orchard, Wash., looked for evidence that water influenced crystal formation in basalt, the dark volcanic rock that covers most of eastern Washington and Oregon. She then compared this with volcanic rock...

Chuck Bednar for redOrbit.com - Your Universe Online Ten years ago Wednesday, Mount St. Helens in Washington erupted after being quiet for nearly two decades, and now US Geological Survey (USGS) scientists are concerned that the volcano could mark the occasion by becoming active once again, various media outlets reported over the weekend. The volcano reawakened in September 2004 and erupted on October 1, remaining active until late January 2008, according to the USGS. That event began...

Marcus Woo, California Institute of Technology In the typical textbook picture, volcanoes, such as those that are forming the Hawaiian islands, erupt when magma gushes out as narrow jets from deep inside Earth. But that picture is wrong, according to a new study from researchers at Caltech and the University of Miami in Florida. New seismology data are now confirming that such narrow jets don't actually exist, says Don Anderson, the Eleanor and John R. McMillian Professor of Geophysics,...

NASA/JPL Scientists have found evidence of plate tectonics on Jupiter's moon Europa. This indicates the first sign of this type of surface-shifting geological activity on a world other than Earth. Researchers have clear visual evidence of Europa's icy crust expanding. However, they could not find areas where the old crust was destroyed to make room for the new. While examining Europa images taken by NASA's Galileo orbiter in the early 2000s, planetary geologists Simon Kattenhorn, of the...

April Flowers for redOrbit.com - Your Universe Online In 1883, a volcanic eruption in a small archipelago of the Dutch East Indies (now Indonesia) changed the world. The eruption and subsequent tsunamis caused by the Krakatau eruption resulted in over 36,000 deaths, including all 3,000 souls on the island. The ocean floor was altered, and temperature and weather patterns didn't return to normal for 5 years. And although the ash in the atmosphere produced spectacular sunsets, the lowered...
