'Sigmoids' are S-shaped structures found in the outer atmosphere of the Sun (the corona), seen with X-ray telescopes and thought to be a crucial part of explosive events like solar flares. Now a group of astronomers have developed the first model to reproduce and explain the nature of the different stages of a sigmoid's life. Professor Alan Hood and Dr. Vasilis Archontis, both from the Mathematical Institute at St. Andrews University, Scotland, will present the team's results at the European...

Warning: Material contained in this story may make you wish to become a solar physicist. Japan's Hinode spacecraft, launched in 2006 on a mission to study the sun, is beaming back movies that astonish even seasoned investigators. Click to play: "That was a polar crown prominence recorded by Hinode on Nov. 30, 2006," says Dr. Thomas Berger of Lockheed Martin's Advanced Technology Center in Palo Alto, California. "It is a curved wall of 10,000o plasma about 90,000 km long and 30,000 km tall." A...

A new cycle of solar activity, which will reach its peak in 2011-2012, will bring large emissions of radiation and cause social unrest on the Earth, Academic Adviser of the Russian Academy of Engineering Sciences Yuri Zaitsev told Interfax-AVN. "Scientists expect a new cycle of solar activity and are trying to predict what the 24th cycle would be like. The cycle begins with a series of major solar flares, which shows that the entire period will not be easy," he said. He said the largest...

The sun has been laying low for the past couple of years, producing no sunspots and giving a break to satellites.That's good news for people who scramble when space weather interferes with their technology, but it became a point of discussion for the scientists who attended an international solar conference at Montana State University. Approximately 100 scientists from Europe, Asia, Latin America, Africa and North America gathered June 1-6 to talk about "Solar Variability, Earth's Climate and...

On April 9, the Sun erupted and blasted a bubble of hot, ionized gas into the solar system. The eruption was observed in unprecedented detail by a fleet of spacecraft, revealing new features that are predicted by computer models but difficult to see in practice.The observations are being discussed today in a press briefing at the American Geophysical Union Joint Assembly in Fort Lauderdale, Fla.Such eruptions, called coronal mass ejections or CMEs, happen periodically and pose a potential...

A plethora of latest results from the Hinode solar observatory contains a wealth of new discoveries. This includes the discovery of a source of the slow solar wind and the observation of a superhot micro flare.Source of the slow solar windAn international team of scientists, led by Prof. Louise Harra, University College London, Mullard Space Science Laboratory, has found a source of the stream of particles that make up the slow solar wind using data from Hinode and SOHO. The solar wind can...

Powerful magnetic waves have been confirmed for the first time as major players in the process that makes the sun's atmosphere strangely hundreds of times hotter than its already superhot surface. The magnetic waves — called Alfven waves — can carry enough energy from the sun's active surface to heat its atmosphere, or corona. "The surface and corona are chock full of these things, and they're very energetic," said Bart de Pontieu, a physicist at the Lockheed Martin...

Imagine you are sitting around a campfire. Move closer to the fire, and you get hotter. Move away, and you get cooler. Pretty basic, right? Well, the closest star, our sun, doesn't seem to be getting this. As you move away from the solar surface, into the sun's outer atmosphere, the corona, it actually gets a lot hotter before it cools off. The solar surface is about 10,000 degrees Fahrenheit, while temperatures in the corona soar to millions of degrees. Although scientists have some ideas...
