Volcano Photo Reveals Shock Wave
An amazing new picture from space reveals a volcanic eruption in its earliest stage, with a huge plume of ash and steam billowing skyward and creating a shock wave in the atmosphere.
The new photo was taken June 12 from the International Space Station. NASA says volcano researchers are excited about the picture "because it captures several phenomena that occur during the earliest stages of an explosive volcanic eruption."

NASA Scientists Bring Light to Moon's Permanently Dark Craters
A new lunar topography map with the highest resolution of the moon's rugged south polar region provides new information on some of our natural satellite's darkest inhabitants – permanently shadowed craters. The map was created by scientists at NASA's Jet Propulsion Laboratory, Pasadena, Calif., who collected the data using the Deep Space Network's Goldstone Solar System Radar located in California's Mojave Desert.

A new analysis of the current swine-origin H1N1 influenza A virus suggests that transmission to humans occurred several months before recognition of the existing outbreak.The work, published online in Nature June 10, highlights the need for systematic surveillance of influenza in swine, and provides evidence that new genetic elements in swine can result in the emergence of viruses with pandemic potential in humans.

Peculiar, Junior-sized Supernova Discovered By New York Teen
According to Science Daily,in November 2008, Caroline Moore, a 14-year-old student from upstate New York, discovered a supernova in a nearby galaxy, making her the youngest person ever to do so. Additional observations determined that the object, called SN 2008ha, is a new type of stellar explosion, 1000 times more powerful than a nova but 1000 times less powerful than a supernova. Astronomers say that it may be the weakest supernova ever seen.

Drinking Water From Air Humidity
Not a plant to be seen, the desert ground is too dry. But the air contains water, and research scientists have found a way of obtaining drinking water from air humidity. The system is based completely on renewable energy and is therefore autonomous.

NASA Scientists Find Evidence For Liquid Water On A Frozen Early Mars
NASA scientists modeled freezing conditions on Mars to test whether liquid water could have been present to form the surface features of the Martian landscape.
Researchers report that fluids loaded with dissolved minerals containing elements such as silicon, iron, magnesium, potassium and aluminum, can remain in a liquid state at temperatures well below freezing. The results of this research appear in the May 21 issue of Nature magazine entitled "Stability Against Freezing of Aqueous Solutions on Early Mars."
