 | 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. ...> Full Article |
 | Red dwarf unleashes the brightest flare ever detected from a normal star outside our solar system ...> Full Article |
 | Satellite data shows clearly that powerful starquakes ripple around the Sun in the wake of mighty solar flares that explode above its surface. The observations give solar physicists new insight into a long-running solar mystery and may even provide a way of studying other stars. ...> Full Article |
 | The appearance of a very special solar spot on the sun surface a few days ago, signalled to scientists around the world that a new solar cycle had begun. This solar spot also produced two solar blasts. ...> Full Article |
 | A new 11-year cycle of heightened solar activity, bringing with it increased risks for power grids, critical military, civilian and airline communications, GPS signals and even cell phones and ATM transactions, showed signs it was on its way late Thursday when the cycle's first sunspot appeared in the sun's Northern Hemisphere, NOAA scientists said. ...> Full Article |
 | Using observations from ESO's VLT, astronomers were able for the first time to reconstruct the site of a flare on a solar-like star located 150 light years away. The study of this young star, nicknamed 'Speedy Mic' because of its fast rotation, will help scientists better understand the youth of our Sun. ...> Full Article |
 | Using the Sun Earth Connection Coronal and Heliospheric Investigation (SECCHI) instruments on board NASA's Solar Terrestrial Relations Observatory (STEREO) spacecraft, a consortium of scientists has seen, for the first time, large waves of solar material sweeping past Earth. ...> Full Article |
 | The Sun is minimally active right now, but this quiet state of affairs won't last for long. Over the next few years, the number of solar flares and eruptions known as coronal mass ejections will increase until reaching solar maximum in 2011 or 2012. Such eruptions can impact Earth, disrupting satellites, communications, and even power grids. Some predict the next solar cycle will be the most intense in 50 years. As a result, scientists are striving to understand the mechanism behind solar eruptions in hopes of eventually being able to predict them in a space "weather forecast." ...> Full Article |

 | As reservoirs of valuable information go, nothing beats the sun. This sphere of heat and energy holds 99.9 percent of the solar system, saved in all original proportions after planets and meteorites formed. Analyzing the mix of hydrogen, oxygen and noble gases found in the sun can answer one of the biggest questions of the universe: How did our solar system evolve? ...> Full Article |
 | Scientists for the first time have observed elusive oscillations in the sun's corona, known as Alfvén waves, that transport energy outward from the surface of the sun. The discovery may give researchers more insight into solar magnetic fields, eventually leading to a better understanding of how the sun affects Earth's atmosphere and the entire solar system.

 | Observations of solar flares by spacecraft at Mars, Venus and the Earth show that eruptions on the far side of the Sun may affect our "space weather" back on Earth. ...> Full Article |
 | A year after launch, scientists working with Hinode, a Japanese mission with ESA participation, are meeting at Trinity College, Dublin, to discuss latest findings on solar mysteries - including new insights on solar flares and coronal heating. ...> Full Article |
