ISS detector finds dark matter clues
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.
The Alpha Magnetic Spectrometer (AMS) surveys the sky for high-energy particles, or cosmic rays.
It has seen evidence for what could be dark matter colliding with itself in a process known as "annihilation".
AMS deputy spokesman Roberto Battiston, a professor of physics at Trento University, Italy, describes the purpose of the AMS experiment.
