Using data from NASA's Interstellar Boundary Explorer (IBEX) spacecraft, an international team of researchers has measured neutral "alien" particles entering our solar system from interstellar space. A suite of studies published in the Astrophysical Journal provide a first look at the constituents of the interstellar medium, the matter between star systems, and how they interact with our heliosphere.
