The most recent shock wave, first observed in February 2014, still appears to be going on. One wave, previously reported, helped researchers determine that Voyager 1 had entered interstellar space. The “tsunami wave” that NASA’s Voyager 1 spacecraft began experiencing earlier this year is still propagating outward, according to new results. It is the longest-lasting shock wave that researchers have seen in interstellar space. ![]() This artist’s concept shows NASA’s Voyager spacecraft against a backdrop of stars.

NASA developing ECOSTRESS instrument to analyze plant reactions to heat and water stressWritten by Alan Buis
When people lose water through their pores, the process is called sweating. The related process in plants is known as transpiration. Because water that evaporates from soil around plants also affects the amount of water that plants can use, ECOSTRESS will measure combined evaporation and transpiration, known as evapotranspiration. «Read the rest of this article» Sections: Technology | No Comments
NASA study reveals the moon Titan may have formed earlier than it’s host, SaturnWritten by Preston Dyches and Whitney Clavin
The finding rules out the possibility that Titan’s building blocks formed within the warm disk of material thought to have surrounded the infant planet Saturn during its formation. ![]() New research on the nitrogen in Titan’s atmosphere indicates that the moon’s raw materials might have been locked up in ices that condensed before Saturn began its formation.

NASA Scientists link Industrial Soot to Abrupt Retreat of 19th Century Glaciers
The research, published September 3rd in the Proceedings of the National Academy of Sciences, may help resolve a longstanding scientific debate. ![]() This photo from summer 2012 looking south into the Bernese Alps shows how air pollution in the Alps tends to be confined to lower altitudes, concentrating the deposition of soot and dust on the lower slopes. At center left in the picture, a glacier can be seen extending from a high-altitude snow field, above the pollution layer, down into the valley where its lower reach is bathed in pollutants.
