Hurricane Fallout: Finding Out How Much Rain Really Falls During Storms Science Daily
How can one know how much rain really falls over the path of a tropical storm or hurricane? This is a question that greatly interests meteorologists and hydrologists. On their behalf, and on behalf of the public which ultimately benefits from better observations of storms, NASA scientists are using satellite data from its rain gauge in space, the Tropical Rainfall Measuring Mission or "TRMM" to
Distorted solar system discovered USA Today
Discovered just 11 years ago, a class of oddball "failed stars" continues to baffle as well as enlighten astronomers. Now researchers have spotted for the first time one of these failed stars, called a brown dwarf, with a companion planet both orbiting a sun-like star.
More rain, winds pummel Saunders County Gretna Breeze

Finding truth in the Flathead Billings Gazette
YELLOW BAY - For most of the summer, a blue catamaran raft has been plying Flathead rivers with a distinct array of high-tech equipment. A strange sonar device called an acoustic Doppler juts from the raft frame into the water. It's connected to a la
