redOrbit Staff & Wire Reports - Your Universe Online NASA’s Cassini spacecraft has recorded the highest-resolution video to date of a unique six-sided jet stream located near Saturn’s north pole, the US space agency announced. This movie is the first to capture the phenomenon also known as the 'hexagon' using color filters, and is also the first footage to show a complete view of the top of the planet down to approximately 70 degrees latitude, NASA said. “Spanning about...

Earth's Van Allen Belts Thrust Particles To Near The Speed Of Light
2013-12-04 14:38:49

Lee Rannals for redOrbit.com - Your Universe Online NASA’s twin Van Allen Probes have led to another new discovery of Earth’s mysterious radiation belts. Researchers used data from the NASA spacecraft to reveal that the high-energy particles populating the Van Allen radiation belts can be accelerated to nearly the speed of light. This finding comes on the heels of a related discovery showing similar particle acceleration but on a microscopic, rather than planetary, scale. “The...

Pioneer Jupiter 40th anniversary

How Solar Cycles Impact Our Weather Here On Earth
2013-01-13 09:10:34

Solar cycles: what are they and why should we care about them? Solar cycles are made up of what are known as solar minimums (min) and solar maximums (max). We refer to a solar min at the time when the sun is not active with many sunspots, while a solar max is just the opposite when we see a large increase in sunspot activity. So how long do solar cycles last? Typically they run on what is known as an 11 year cycle from the max to the min and then start over again anew. As of 2012 we...
