Submission + - NASA finds 'Alien' Matter From Beyond Our Solar Sy (

An anonymous reader writes: For the very first time, a NASA spacecraft has detected matter from outside our solar system — material that came from elsewhere in the galaxy, researchers announced today (Jan. 31).
This so-called interstellar material was spotted by NASA's Interstellar Boundary Explorer (IBEX), a spacecraft that is studying the edge of the solar system from its orbit about 200,000 miles (322,000 kilometers) above Earth.

"This alien interstellar material is really the stuff that stars and planets and people are made of — it's really important to be measuring it," David McComas, IBEX principal investigator and assistant vice president of the Space Science and Engineering Division at Southwest Research Institute in San Antonio, said in a news briefing today from NASA Headquarters in Washington, D.C.
