Shocks are some of the oldest known, most intensely studied space plasma phenomena. They are implicated in the production of solar energetic particles and galactic cosmic rays, both important for space weather. Yet questions remain about how they ...

A major challenge in space science is understanding how highly localized regions, far smaller than 1 degree at the Sun, are the source of solar wind structures spanning more than 20 degrees near Earth. The Sun’s atmosphere is divided into &l...

Hong Zhao of the University of Colorado produced an extremely impressive Ph.D. dissertation titled “Unveiled characteristics of energetic electrons and ions: The inner radiation belt, slot region, and ring current.” It contains a numbe...

The variation in the radiative output of the Sun, described in terms of solar irradiance, is critical to climatology, especially as climate models rely on model reconstructions of historical solar irradiance variability. The work of Kok Leng Yeo h...
