| Blame it on the rain (from Saturn's rings): More charged water particles fall than thought Posted: 10 Apr 2013 05:23 PM PDT A new study tracks the "rain" of charged water particles into the atmosphere of Saturn and finds there is more of it and it falls across larger areas of the planet than previously thought. The study, whose observations were funded by NASA and whose analysis was led by the University of Leicester, England, reveals that the rain influences the composition and temperature structure of parts of Saturn's upper atmosphere. |
| Posted: 10 Apr 2013 05:27 AM PDT Scientists have known for almost a decade that thunderstorms are capable of generating brief but powerful bursts of gamma-rays called terrestrial gamma-ray flashes, or TGFs. Because they can originate near the same altitudes at which commercial aircraft routinely fly, scientists have been trying to determine whether or not terrestrial gamma ray flashes present a radiation hazard to individuals in aircraft. In the middle of the storm, radiation doses could be roughly equal to a full-body CT scan, preliminary research suggests. |
