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

Far beyond the orbits of the planets are the hazy outlines of the heliosphere, the magnetic bubble in space that we call home. This flexible cosmic bubble stretches and shrinks in response to the sun’s gasps and sighs. Now, for the first time, a team of scientists led by Princeton’s David McComas have gathered an entire solar cycle of data from NASA’s IBEX spacecraft, which they used to study how the heliosphere changes over time.
