The International Space Station (ISS) may have detected the elusive so-called dark matter, which is believed to be the glue that holds the universe together. The discovery comes from the Alpha Magnetic Spectrometer on-board the ISS, which has detected about 400,000 positrons.
Positrons are the antimatter partner particle of electrons. Positrons have been detected before, but these are a little different in composition. They have an energy signature that suggest they might have been formed when particles of dark matter collided with other particles of dark matter.
In other space news, Saturn has once again returned to the northern hemispheres nighttime skies. Saturn has always been my favorite object to view, not just because of its beauty, but because it's easy to find and view with minimal equipment. A decent set of binoculars as well as cheap department store telescopes can all resolve Saturn and its rings and you might even be able to notice some color in the rings if the skies are clear enough.
