The edge of the Solar System

is a very mysterious place, as further revealed by the IBEX mission. Read more about the latest mysteries here.

The Ribbon at the End of the Solar System

I definitely plan on discussing this in more detail on a future show, but the IBEXspacecraft recently detected that high-energy neutrons accelerated where the solar wind meets the rest of the Milky Way come from a large ribbon on the sky, not the point in the direction of the Sun's motion as expected. Now, there might be an answer. Go here to read more.

IBEX Spacecraft launched

Dropped from an airplane, the rocket which contains the IBEX spacecraft flew into orbit this Sunday. To watch the launch go here.

NASA's newest astronomy mission - IBEX

NASA hopes to launch its newest astronomy satellite, the Interstellar Boundary Explorer (IBEX), soon. The goal of this mission is to study the "termination shock" formed when the Solar wind is decelerated by the "interstellar medium" (diffuse hydrogen gas, for the most part) that fills the Milky Way - a boundary recently crossed by both Voyager missions.
