| As it circles the Earth, NASA’s Interstellar Boundary Explorer hunts for particles streaming in from beyond the solar system. It has now intercepted atoms of hydrogen, helium, neon and oxygen. IBEX principal investigator Dave McComas discusses how the abundance of those atoms hints at what the Milky Way is made of. |
