New Doubt About Dark Matter 2014-12-20T05:00:00Z “The magnetic fields are constant, the flux of cosmic rays is constant”—a sharp contrast to the turmoil of the so-called termination shock, where particles racing outward at a million m.p.h. Voyager 1 is Rocked By a Solar Storm 2014-12-17T05:00:00Z But theory says they should be there, generated in whatever giant explosions also create cosmic rays. Balloon with a view 2014-12-04T05:00:00Z The dark-matter riddle relates to an unexpected excess of positrons — the antimatter partners of electrons — among cosmic rays, highly energetic particles swirling around the galaxy. European probe shoots down dark-matter claims 2014-12-01T05:00:00Z Owens says what they think is happening is the Sun's magnetic field affects the Earth’s magnetic field, stretching and skewing it, which allows more cosmic rays to hit the atmosphere. Sun's Magnetic Field Boosts Earth Lightning 2014-11-24T05:00:00Z Current theories hold that high energy particles called galactic cosmic rays provide the necessary link that lets the current flow into a lightning bolt. Sun boosts UK lightning strikes 2014-11-18T05:00:00Z The most powerful cosmic rays, however, which carry millions of times more energy than anything produced at the Large Hadron Collider, remain a mystery. Seeking the Source of Cosmic Rays 2014-10-28T04:00:00Z This led to his role in two high altitude projects, first Manhigh, to study the effects of cosmic rays on humans, then Excelsior, to test a parachute system for pilots ejecting at high altitude.
