Alien Matter in the Solar System: A Galactic Mismatch

Researchers announced the finding at a press conference on Jan. 31, 2012. It's based on data from NASA's IBEX spacecraft, which is able to sample material flowing into the solar system from interstellar space.

"We've detected alien matter that came into our solar system from other parts of the galaxy--and, chemically speaking, it's not exactly like what we find here at home." says David McComas the principal investigator for IBEX at the Southwest Research Institute in San Antonio, Texas.
