... Mars to Appear Normal this August . ... October is the best month to see Mars this year. ... As Earth catches up to Mars in their respective orbits around the Sun, Mars will keep rising earlier in the night. On 2005 October 30, Earth will have caught up to Mars and the planets will be the nearest to each other in their orbits -- this time around. On October 30, Mars will be nearly opposite to the Sun, rise at sunset, set at sunrise, and appear highest and brightest around midnight. ...

It's a common misconception that black holes always have matter swirling into them. ... As this matter gets closer and closer to the black hole it piles up and a large, fairly flat disk forms. This is called the accretion disk , because matter from this disk accretes (that is, falls in) on the black hole. ... 2008 Phil Plait. ...

The trapping of particles by magnetic fields was first studied by Kristian Birkeland in Norway, starting around 1895. ... Poincare managed to solve the motion of charged particles near an isolated magnetic pole, showing that they spiraled around field lines and that they were repelled from regions of strong field. ... A more realistic problem, of more interest to Birkeland, was particle motion near a compact bar magnet or "dipole", which better approximated the field of the Earth or of his terrella. ...

. On August 31, 2012, a giant prominence on the Sun erupted, sending out particles and a shock wave that traveled near Earth. This event may have been one of the causes of a third radiation belt that appeared around Earth a few days later, a phenomenon that was observed for the first time by the newly launched Van Allen Probes. This image of the prominence before it erupted was captured by NASA's Solar Dynamics Observatory (SDO). // NASA/SDO/AIA/GSFC

... Trapped Motion . ... The trapping of particles by magnetic fields was first studied by Kristian Birkeland in Norway, starting around 1895. ... Perhaps the most interesting story of that era concerns Nicholas Christofilos , a Greek elevator engineer whose avocation was the study of particle motion in magnetic fields. ... Atomic bombs produce large numbers of energetic electrons, and Christofilos hoped that such electrons would become trapped in the magnetic field as an artificial radiation belt. ...
