taken from two different angles. Project scientist Robbie Hood of the Space Sciences Laboratory at Marshall Space Flight Center said the effect is based on what many boaters...
explosions—often, but not always, in tandem with a solar flare. CMEs hitting Earth can spark geomagnetic storms and Northern Lights. CMEs often announce themselves with...
plasma waves -- a telltale sign of a magnetosphere around the moon. That discovery marked Ganymede as not only the largest moon in our solar system, but also the only one...
Sun's surface produced by sound waves reverberating through the Sun. Analysis of solar sound waves is the science of helioseismology, and it opened the Sun's gaseous interior...
absorbing numerous small galaxies in the past billion years. Alternatively the shells may be like ripples in a pond, where a recent collision with another large galaxy...
gas at 1200 kilometers per second. Such spectacular cosmic mergers are thought to be common in crowded galaxy cluster environments in the distant universe. In their final...
relevant to NASA's programs in astronomy and astrophysics and includes research over the entire range of photons, gravitational waves, and particle astrophysics. Proposals...
disk and an outward moving jet. The disk is shown in radio waves taken by the Atacama Large Millimeter Array (ALMA) in Chile, and show gaps likely created by the...
Observatory is shown in orange (hot), green (hotter), and purple (hottest) and superposed with a highly detailed image in radio waves, shown in gray, acquired by the...
telescopes, an array of optical telescopes that will help locate optical counterparts to gravitational waves detections by LIGO and other detectors. But there is much...
