Spectacular video: Comet ISON imaged from a Langrange point in space

NASA’s Solar Terrestrial Relations Observatory, or STEREO, is monitoring Comet ISON as it approaches the sun. NASA’s twin Solar Terrestrial Relations Observatory (STEREO) spacecraft are parked in Langrange zones, known as the L4 and L5 Lagrangian points, each centered about 93 million miles away along Earth’s orbit. The latest movie from the STEREO-A spacecraft’s Heliospheric…

New paper suggests the sun’s magnetic fields defines climate over the long term

Story submitted by Cornelis de Jager (past president ICSU;past pres. COSPAR) In a recent publication entitled Terrestrial ground temperature variation in relation to solar magnetic variability, including the present Schwabe cycle, Cornelis (Kees) de Jager and Hans Nieuwenhuijzen, from the Space Research Organisation of the Netherlands have analysed the dependence of the global earth temperature…

70-year-old conundrum of the hot solar corona may be solved

From Columbia University Astronomers find clues to decades-long coronal heating mystery Drs. Michael Hahn and Daniel Wolf Savin, research scientists at Columbia University’s Astrophysics Laboratory in New York, NY, found evidence that magnetic waves in a polar coronal hole contain enough energy to heat the corona and moreover that they also deposit most of their…

September doldrums – solar slump continues

While many science related government agencies are shut down (NASA GISS is deemed ‘non-essential’ for example) some remain open due to statements like this: Due to the Federal Government shutdown, NOAA.gov and most associated web sites are unavailable. However, because the information this site provides is necessary to protect life and property, it will be…
