Interstellar Boundary Explorer (IBEX) has explored some alien material outside our vast solar system. IBEX was sent to discover the nature of the interactions between the solar wind and the interstellar medium on October 19, 2008. It is exploring the interaction at the edge of solar system.

Explorations revealed that there is more Oxygen in solar system than in the local interstellar space. Probably a very amazing outcome. The ratio suggests that for every 20 neon atoms there are 70 oxygen atoms in local interstellar space while 111 oxygen atoms in ratio with every 20 neon atoms in our solar system.

Mission scientist for IBEX, Eric Christian said, “We’ve directly measured four separate types of atoms from interstellar space and the composition just doesn’t match up with what we see in the solar system. IBEX’s observations shed a whole new light on the mysterious zone where the solar system ends and interstellar space begins”.
