The Sun's coronal tail wags its photospheric dog
Newark NJ (SPX) Oct 19, 2016
Solar physicists have long viewed the rotation of sunspots as a primary generator of solar flares - the sudden, powerful blasts of electromagnetic radiation and charged particles that burst into space during explosions on the sun's surface. Their turning motion causes energy to build up that is released in the form of flares. But a team of NJIT scientists now claims that flares in turn have a powerful impact on sunspots, the visible concentrations of magnetic fields on the sun's surface, or photos ... read more

Wayward Field Lines Challenge Solar Radiation Models In addition to the constant emission of warmth and light, our sun sends out occasional bursts of solar radiation that propel high-energy particles toward Earth. These solar energetic particles, or S ... more		How Deadly Would A Nearby Gamma Ray Burst Be? Despite the obvious doom and gloom associated with mass extinctions, they have a tendency to capture our imagination. After all, the sudden demise of the dinosaurs, presumably due to an asteroid str ... more		Two-dimensional spin-orbit coupling for Bose-Einstein condensates realized Spin-orbit coupling is one of the fundamental effects in quantum physics. It plays a vital role in many basic physic phenomena and exotic quantum states. These phenomena led to the foundation of sev ... more

				Proxima Centauri might be more sunlike than we thought In August astronomers announced that the nearby star Proxima Centauri hosts an Earth-sized planet (called Proxima b) in its habitable zone. At first glance, Proxima Centauri seems nothing like our S ... more		Lights, action, electrons! Ever since J.J. Thompson's 1897 discovery of the electron, scientists have attempted to describe the subatomic particle's motion using a variety of different means. Electrons are far too small and f ... more
