Scientists at George Mason University discovered that a phenomenon called a giant magnetic rope is the source for solar storms. The researchers made the discovery by using images from the NASA Solar Dynamic Observatory (SDO) spacecraft. Scientists had previously been unable to prove that the magnetic rope was the cause of solar storms. However, using images taken by the Atmospheric Imaging Assembly (AIA) telescope aboard the SDO, the team was able to pinpoint an area of the sun where a...

WASHINGTON, June 9, 2011 /PRNewswire-USNewswire/ -- Observations from NASA's Voyager spacecraft, humanity's farthest deep space sentinels, suggest the edge of our solar system may not be smooth, but filled with a turbulent sea of magnetic bubbles. (Logo: http://photos.prnewswire.com/prnh/20081007/38461LOGO) While using a new computer model to analyze Voyager data, scientists found the sun's distant magnetic field is made up of bubbles approximately 100 million miles wide. The bubbles are...

Bubbles are blocking the current path of one of the most promising high temperature superconducting materials, new research suggests. In a study published today, Monday, 16 may, in IOP Publishing's journal Superconductor Science and Technology, researchers have examined bismuth strontium calcium copper oxide (Bi2Sr2CaCu2Ox, Bi2212) "“ one of the most promising superconducting materials capable of creating large magnetic fields way beyond the limit of existing magnets "“ and found...

According to researchers, humpback whales can swim thousands of miles in a straight line, which suggests that they may use a unique compass mechanism. "They maintain remarkably straight movements for weeks across thousands of kilometers of oceans," lead author, environmental scientist Dr Travis Horton, of the University of Canterbury in Christchurch, New Zealand, said in a statement. Many animals are believed to navigate using a compass cue, like the Sun or the Earth's magnetic field, which...

A dramatic and surprising magnetic effect of light discovered by University of Michigan researchers could lead to solar power without traditional semiconductor-based solar cells. The researchers found a way to make an "optical battery," said Stephen Rand, a professor in the departments of Electrical Engineering and Computer Science, Physics and Applied Physics. In the process, they overturned a century-old tenet of physics. "You could stare at the equations of motion all day and you will not...

Researchers at the University of Central Lancashire studied the largest solar flare recorded in nearly five years. The solar eruption in February was caused by five rotating sunspots working in concert, BBC News reports. Solar flares are eruptions on the surface of the sun which begin as concentrated magnetic fields and are visible as sunspots. As the magnetic fields build up, they twist and erupt, releasing vast amounts of heat, light and radiation."Twisting the Sun's magnetic field is like...

Researchers discover a rare physical phenomenon at low temperatures and high magnetic fields Just in time for the 100th anniversary to commemorate the discovery of superconductivity by the Dutch physicist Heike Kamerlingh Onnes on April 8, 1911, scientists from the Helmholtz-Zentrum Dresden-Rossendorf and the TU Dresden published their research results in the journal Physical Review B. Headed by Dr. Thomas Herrmannsdörfer, the team from the HZDR's High Magnetic Field Laboratory (HLD)...

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...
