The Extreme Ultraviolet Imaging Spectrometer (EIS), on board the Japanese-UK-US Hinode satellite, is now generating unprecedented observations enabling scientists to provide a new perspective on the 50-year old question of how solar wind is driven.

UCLA atmospheric scientists have discovered a previously unknown basic mode of energy transfer from the solar wind to the Earth's magnetosphere. The research, federally funded by the National Science Foundation, could improve the safety and reliability of spacecraft that operate in the upper atmosphere.

Researchers at the University of Warwick have found what could be the signal of ideal wave “surfing” conditions for individual particles within the massive turbulent ocean of the solar wind. The discovery could give a new insight into just how energy is dissipated in solar system sized plasmas such as the solar wind and could provide significant clues to scientists developing fusion power which relies on plasmas.

Two places on opposite sides of Earth may hold the secret to how the moon was born. NASA's twin Solar Terrestrial Relations Observatory (STEREO) spacecraft are about to enter these zones, known as the L4 and L5 Lagrangian points, each centered about 93 million miles away along Earth's orbit.

Yesterday, Feb. 12th at 1625 UT, an ultraviolet telescope onboard NASA's STEREO-B spacecraft recorded the following images of a faint yet powerful "solar tsunami" eruption through the Sun's lower atmosphere:
The solar activity has been attributed to Sunspot 1012 which has been crackling with B-class solar flares of late. The low latitude and magnetic polarity of this sunspot identify it as a member of old Solar Cycle 23. It is, in other words, a fossil, albeit a relatively active one. Stay tuned for more flares.

January 24, 2009 marks the point at which the two STEREO spacecraft reach 90 degrees separation, a condition known as quadrature. Since the two STEREO spacecraft went into orbit around the Sun at the beginning of 2007, they have been slowly drifting apart from Earth, and from each other. After two years in solar orbit, the two spacecraft have finally reached quadrature.
