NASA’s IBEX charts 11 years of change at boundary to interstellar space

Now, for the first time, scientists have used an entire solar cycle of data from NASA’s IBEX spacecraft to study how the heliosphere changes over time. Solar cycles last roughly 11 years, as the Sun swings from seasons of high to low activity, and back to high again. The results show the shifting outer heliosphere in great detail and hint at processes behind one of its most puzzling features.
