Using NASA's Far Ultraviolet Spectroscopic Explorer (FUSE) satellite and ground-based telescopes, astronomers have determined, for the first time, the properties of a rare, extremely massive, and young binary star system.
Sky-Sailor, the working dream of a solar-powered, autonomously-controlled microairplane, has exciting implications in two areas: one on the technological advances of unmanned air vehicles (UAVs); and another on exploring ...
Evidence is mounting: the next solar cycle is going to be a big one. Solar cycle 24, due to peak in 2010 or 2011 "looks like its going to be one of the most intense cycles since record-keeping began almost 400 years ago," ...
In a recent study, fuel cell expert Ulf Bossel explains that a hydrogen economy is a wasteful economy. The large amount of energy required to isolate hydrogen from natural compounds (water, natural gas, biomass), package ...
Concentrations of atmospheric ozone -- which protects Earth from the sun's ultraviolet radiation -- are showing signs of recovery in the most important regions of the stratosphere above the mid-latitudes in both the Northern ...
“Despite differences in the chemical compositions and densities of Earth’s and Mars’ atmospheres, we now have a definitive example showing that both planets’ atmospheres react similarly to varying levels of solar ...
The Sun's Great Conveyor Belt has slowed to a record-low crawl, according to research by NASA solar physicist David Hathaway. "It's off the bottom of the charts," he says. "This has important repercussions for future solar ...
Studies have shown that over the last 40 years, a warming climate has been accompanied by fewer rain- and snow-producing storms in mid-latitudes around the world, but the storms that are happening are a little stronger with ...
The next sunspot cycle will be 30-50% stronger than the last one and begin as much as a year late, according to a breakthrough forecast using a computer model of solar dynamics developed by scientists at the National Center ...
