The space station's Alpha Magnetic Spectrometer has picked up evidence that could indicate dark matter.
The $2 billion experiment is tasked with surveying the skies for high-energy particles in an effort to help scientists understand the formation of the universe. Sometimes referred to as the 'Space LHC' after the Large Hadron Collider, the AMS has detected possible evidence of a process known as "annihilation" which is thought to occur when dark matter collides with itself. It isn't clear if this is definitely what has been picked up but it does offer tantalizing new details in the hunt for proof that dark matter exists.
"It could take a few more years," said deputy spokesman Roberto Battiston. "But the accuracy that AMS is displaying is far greater than past experiments, so we're getting closer to unveiling the cause of the particle events we're detecting."
"A $2bn experiment on the space station has made observations that could prove to be the first signs of dark matter, a mysterious component of the Universe."
