Lee Rannals for redOrbit.com - Your Universe Online Ball lightning is a phenomenon that has puzzled some of the best minds for generations, including Aristotle and Nikola Tesla. Now, scientists from the US Air Force Academy say they have some new insights into reproducing the rare form of lightning in the laboratory. The phenomenon consists of a floating, glowing ball that drifts eerily through the sky and then explodes violently. It sometimes can injure people and damage buildings....

Our Sun experiences regular eruptions of material into space, but solar physicists still have difficulty in explaining why these dramatic events take place. Now a group of scientists from the University of St Andrews think they have the answer: clouds of ionized gas (plasma) constrained by magnetic fields and known as 'plasmoids' that struggle to break free of the Sun's magnetic field. Dr Vasilis Archontis will present their work on Monday 18 April at the National Astronomy Meeting in...

Invisible to the naked eye, yet massive in structure around the Earth is the magnetosphere, the region of space around the planet that ebbs and flows in response to the million-mile-per-hour flow of charged particles continually blasting from the Sun. NASA's Interstellar Boundary Explorer (IBEX) spacecraft, designed to image the invisible interactions occurring at the edge of the solar system, captured images of magnetospheric structures and a dynamic event occurring in the magnetosphere as...


Word of the Day
tesla
  • The unit of magnetic flux density in the International System of Units, equal to the magnitude of the magnetic field vector necessary to produce a force of one newton on a charge of one coulomb moving perpendicular to the direction of the magnetic field vector with a velocity of one meter per second. It is equivalent to one weber per square meter.
This word is named for Nikola Tesla, the inventor, engineer, and futurist.
