NASA scientists demonstrate technique to improve particle warnings that protect astronauts

Our constantly-changing sun sometimes erupts with bursts of light, solar material, or ultra-fast energized particles--collectively, these events contribute to space weather. In a study published Jan. 30, 2017, in Space Weather, scientists from NASA and the National Center for Atmospheric Research, or NCAR, in Boulder, Colorado, have shown that the warning signs of one type of space weather event can be detected tens of minutes earlier than with current forecasting techniques - critical extra tim...
