NASA Observations Find What Helps Heat Roots of ‘Moss’ on Sun

Did you know the Sun has moss? Due to its resemblance to the earthly plants, scientists have named a small-scale, bright, patchy structure made of plasma in the solar atmosphere “moss.” This moss, which was first identified in 1999 by NASA’s TRACE mission, blossoms around the center of a sunspot group, where magnetic conditions are […]
