Space Instrument Observes New Characteristics of Solar Flares; Findings May Lead to Improved Space Weather Forecasting
September 7, 2011 — NASA's Solar Dynamics Observatory, which is carrying a suite of instruments, has provided scientists with new information that energy from some solar flares is stronger and lasts longer than ... > full storyMore: -
New Method Detects Emerging Sunspots Deep Inside the Sun, Provides Warning of Dangerous Solar Flares
August 19, 2011 — Sunspots spawn solar flares that can cause billions of dollars in damage to satellites, communications networks and power grids. But researchers have now developed a way to detect incipient sunspots ... > full story -
New Images Reveal Structures of the Solar Wind as It Travels Toward and Impacts Earth
August 18, 2011 — Using data collected by NASA's STEREO spacecraft, researchers have developed the first detailed images of solar wind structures as plasma and other particles from a coronal mass ejection traveled 93 ... > full story -
Solar Flares: What Does It Take to Be X-Class? Sun Emits an X-Class Flare on August 9, 2011
August 9, 2011 — Solar flares are giant explosions on the sun that send energy, light and high speed particles into space. These flares are often associated with solar magnetic storms known as coronal mass ejections ... > full story -
Wave Power Can Drive Sun's Intense Heat
July 27, 2011 — A new study sheds light on why the sun's outer atmosphere, or corona, is more than 20 times hotter than its surface. The research may bring scientists a step closer to understanding the solar cycle ... > full storyMore: -
Twin ARTEMIS Probes to Study Moon in 3-D
July 13, 2011 — Almost 2 years ago, two of five THEMIS satellites were boosted from their orbits around Earth toward the moon. The first transitioned into a lunar orbit on June 27, while the second is destined to ... > full story -
New Insights on How Solar Minimums Affect Earth
June 14, 2011 — Since 1611, humans have recorded the comings and goings of black spots on the sun. The number of these sunspots waxes and wanes over approximately an 11-year cycle -- more sunspots generally mean ... > full story -
NASA Sees the Sun Having a Solar Blast
June 7, 2011 — The Sun unleashed an M-2 (medium-sized) solar flare, an S1-class (minor) radiation storm and a spectacular coronal mass ejection (CME) on June 7, 2011 from sunspot complex 1226-1227. The large cloud ... > full story -
NASA Building Instrument to Study Magnetic Reconnection
April 29, 2011 — Whether it's a giant solar flare or a beautiful green-blue aurora, just about everything interesting in space weather happens due to a phenomenon called magnetic reconnection. Several spacecraft have ... > full story -
New Tools to Tackle a Solar Data Storm
April 18, 2011 — So great is the wealth of data about the Sun now being sent back by space missions such as SOHO, STEREO and the Solar Dynamics Observatory (SDO) that scientists back on Earth can struggle to keep ... > full story
