seismic waves from earthquakes to probe inside Earth. In this way, mission scientists hope to map the ebb and flow of the sun's inner magnetic dynamo, the root of all solar...
first-of-its-kind instrument designed to study the dynamics of the magnetosphere by using radar techniques. In order to generate very low frequency radio waves and to receive...
flows beneath the surface of the sun, the jet stream is not directly visible. Hill and Howe tracked its hidden motions via helioseismology. Shifting masses inside the sun...
climate is strongly influenced by oceans, glaciers and ice sheets. Understanding the oceans is clearly important, yet what lies beneath the waves remains largely unexplored...
part of Endeavour's rim on the horizon, about eight miles away, across the ripples of windblown sand. "The ripples look like waves on the ocean, like we're out in the middle...
poster advertising the First Workshop of the International Space Weather Initiative in Helwan, Egypt.[more] A key problem organizers hope to solve is a gap--many gaps,...
simulations of cosmic mergers. This comparison, which is in the early stages, shows that this merger has progressed to an advanced stage. Strong shock waves predicted by the...
produced when the Sun's ultraviolet light ionizes the atoms and molecules in the upper atmosphere. The ionosphere makes long-distance radio communication possible by...
clouds, causing the dust to glow, as is the case with the supernova remnant 1987A. But the ring around the magnetar SGR 1900+14 fits into none of these categories. For one...
most energy of any wave in the electromagnetic spectrum. They are produced by the hottest and most energetic objects in the universe, such as neutron stars and pulsars,...
