Over the last century, astronomers have become very aware of how just dynamic the Sun really is. One of the most dramatic manifestations of this is a coronal mass ejection (CME) where billions of tons of matter is thrown into space. If a CME reaches the Earth it creates inclement "Ëœspace weather' that can disrupt communications, power grids and the delicate systems on orbiting satellites. This potential damage means there is a keen interest in understanding exactly what triggers a...

Scientists are learning to predict giant solar storms that could, at any time, hit the Earth and produce cascading catastrophes From Sept. 1 to 2, 1859, the sun blasted out a massive, record-breaking coronal mass ejection (CME)--a huge eruption of highly charged gases and plasma that may have weighed as much as a billion tons. Racing through the solar system at several million miles per hour, the CME eventually collided with the Earth's magnetosphere--an invisible, atmospheric cocoon...

When NASA's satellite operators need accurate, real-time space-weather information, they turn to the Community Coordinated Modeling Center (CCMC) of the Space Weather Laboratory at NASA's Goddard Space Flight Center in Greenbelt, Md. The CCMC's newest and most advanced space-weather science tool is the Integrated Space Weather Analysis (iSWA) system. The iSWA is a robust, integrated system provides information about space weather conditions past, present, and future and, unlike many other...

A $32 million University of Colorado at Boulder instrument package set for launch Feb. 9 by NASA should help scientists better understand the violent effects of the sun on near-Earth space weather that can affect satellites, power grids, ground communications systems and even astronauts and aircraft crews. The CU-Boulder Extreme Ultraviolet Variability Experiment, or EVE, will fly on NASA's Solar Dynamics Observatory known as SDO, the space agency's first mission as part of its "Living With a...

Solar coronal seismology based on magnetic field-line stretching model of "EIT waves" is proposed, which is demonstrated to be potentially able to probe the mysterious magnetic field in the solar corona. The study, which was led by Dr. Chen, is reported in Issue 52 of Science in China (G) because of its significant research value. Many explosive phenomena on the Sun, such as solar flares, involve the energy conversion from the magnetic energy to thermal and kinetic energies in the corona,...

On August 1, 2008 a total solar eclipse was visible within a narrow corridor that traversed from North America to China. The path of the Moon's umbral shadow started from Canada and extended across northern Greenland, the Arctic, central Russia, Mongolia, and China. A partial eclipse was seen within the much broader path of the Moon's penumbral shadow, which included northeastern part of North America, most parts of Europe and Asia. At a solar physics meeting, held in Kunming, China in the...

Word of the Day
attercop
  • A spider.
  • Figuratively, a peevish, testy, ill-natured person.
'Attercop' comes from the Old English 'atorcoppe,' where 'atter' means 'poison, venom' and‎ 'cop' means 'spider.' 'Coppa' is a derivative of 'cop,' top, summit, round head, or 'copp,' cup, vessel, which refers to 'the supposed venomous properties of spiders,' says the OED. 'Copp' is still found in the word 'cobweb.'
