Solar System “Tail” Mapped by NASA’s IBEX

NASA today announced that its Interstellar Boundary Explorer (IBEX) has mapped the structure of our solar system’s “tail.” The tail, called the heliotail, is shaped like a four-leaf clover, much like the tails seen around other nearby stars. “By examining the neutral atoms, IBEX has made the first observations of the heliotail,” said David McComas, lead author of a paper …

IBEX’s Giant Interstellar “Ribbon” Explained

A new study using data from NASA‘s Interstellar Boundary Explorer (IBEX) mission has put forth an explanation for an interstellar “ribbon” of energetic neutral atoms. The ribbon confounded researchers in 2009 when IBEX was able to map the interstellar boundary at the edge of our heliosphere, where particles from inside the solar system interact with and bounce off galactic material. …
