Once regarded as the stuff of science fiction, antimatter - the mirror image of the ordinary matter in our observable universe - is now the focus of laboratory studies around the world…
Scientists using NASA's Fermi Gamma-ray Space Telescope have detected beams of antimatter produced above thunderstorms on Earth, a phenomenon never seen before…
Physicists working at the European Organisation for Nuclear Research (CERN) in Geneva, Switzerland, have succeeded in trapping antihydrogen - the antimatter equivalent of the hydrogen…
Not all explosions are created equal: It's as true for film effects as it is for the stars. Yet, until now, scientists had only observed two basic kinds of exploding stars, known as…
In the past decade, robotic telescopes have turned astronomers' attention to scads of strange exploding stars, one-offs that may or may not point to new and unusual physics…
Astrophysicists are looking everywhere - inside the Large Hadron Collider, in deep mines and far out into space - for evidence of dark matter, which makes up about 25 percent of the…
Astronomers recently observed a mysterious flux of particles in the universe, and the hope was born that this may be the first observation of the remnants of 'dark matter'…
A team of astrophysicists has solved a mystery that led some scientists to speculate that the distribution of certain gamma rays in our Milky Way galaxy was evidence of a form of undetectable…
Take a gold sample the size of the head of a push pin, shoot a laser through it, and suddenly more than 100 billion particles of anti-matter appear. The anti-matter, also known as positrons,…
Four years of observations from the European Space Agency's Integral (INTErnational Gamma-Ray Astrophysics Laboratory) satellite may have cleared up one of the most vexing mysteries…
