A University of Iowa researcher wants you to visualize a plate of spaghetti when you think of the northern lights. That’s because Jack Scudder, UI professor of physics and astronomy, and his colleagues have reached a milestone in describing how the northern lights work by way of a process called “magnetic reconnection.”
On September 29, the MESSENGER spacecraft will pass by Mercury for the third time, flying 141.7 miles above the planetâ€™s rocky surface for a final gravity assist that will enable it to enter orbit about Mercury in 2011.
As the closest planet to the sun, Mercury is scorching hot, with daytime temperatures of more than 800 degrees Fahrenheit (approximately 450 degrees Celsius).
Researchers have discovered 'magnetic portals' forming high above Earth that can briefly connect our planet to the Sun. Not only are the portals common, one space physicist contends they form twice as often as anyone had previously imagined.
Co-ordinated efforts by China/ESAâ€™s Double Star and ESAâ€™s Cluster spacecraft have allowed scientists to zero in on an area where energetic particles from the Sun are blasting their way through the Earthâ€™s magnetic shield. Solar material penetrating the Earth's magnetic shield can represent a hazard to both astronauts and satellites.
