M-Class Solar Flare EruptsWashington DC (SPX) Aug 10, 2010 An M-class flare erupted in active sunspot region 1093, peaking at 1824 UTC on August 7, 2010. The eruption hurled a coronal mass ejection (CME) into space. NASA's Solar Dynamics Observatory observed the flare. The CME is not fully directed toward Earth, but some of the plasma cloud may glance the magnetosphere between August 9 and August 10, causing a geomagnetic disturbance and possible aurora. Scientists classify solar flares according to their x-ray brightness in the wavelength range 1 t ... read more |

Moffett Field CA (SPX) Aug 04, 2010NASA scientists created a unique collection of polycyclic aromatic hydrocarbon (PAH) spectra to interpret mysterious emission from space. Because PAHs are a major product of combustion, remain in the environment, and are carcinogenic, the value of this PAH spectral collection extends far beyond NASA and astronomical applications. For years, scientists have been studying a mysterious infrar ... more  
Paris, France (SPX) Aug 05, 2010The UNESCO World Heritage Committee, at its 34th session in Brasilia, Brazil, has, for the first time, endorsed a study in science heritage. The thematic study on the Heritage Sites of Astronomy and Archaeoastronomy, prepared within the framework of the International Year of Astronomy 2009, presents an overall vision of astronomical heritage and attempts to identify some of the most outsta ... more  
Leicester, UK (SPX) Aug 05, 2010An international team of scientists led by Dr Jonathan Nichols of the University of Leicester has discovered that Saturn's aurora, an ethereal ultraviolet glow which illuminates Saturn's upper atmosphere near the poles, pulses roughly once per Saturnian day. The length of a Saturnian day has been under much discussion since it was discovered that the traditional 'clock' used to measure the ... more |

Coronal Mass Ejection Headed For EarthWashington DC (SPX) Aug 04, 2010 On August 1st around 0855 UT, Earth orbiting satellites detected a C3-class solar flare. The origin of the blast was Earth-facing sunspot 1092. C-class solar flares are small (when compared to X and M-class flares) and usually have few noticeable consequences here on Earth besides aurorae. This one has spawned a coronal mass ejection heading in Earth's direction. Coronal mass ejections (or CMEs) are large clouds of charged particles that are ejected from the Sun over the course of several hours an ... read more |
