Magnetic Bubbles Reside at Solar System Edge, NASA Probes Suggest
June 9, 2011 — 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 ... > 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's Solar Dynamics Observatory Catches 'Surfer' Waves on the Sun
June 7, 2011 — Scientists have spotted the iconic surfer's wave rolling through the atmosphere of the sun. The waves hold clues as to how energy moves through that atmosphere, known as the corona. Since scientists ... > full story -
New Solar System Formation Models Indicate That Jupiter's Foray Robbed Mars of Mass
June 5, 2011 — Planetary scientists have long wondered why Mars is only about half the size and one-tenth the mass of Earth. As next-door neighbors in the inner solar system, probably formed about the same time, ... > full story -
NASA's Fermi Spots 'Superflares' in the Crab Nebula
May 11, 2011 — The famous Crab Nebula supernova remnant has erupted in an enormous flare five times more powerful than any flare previously seen from the object. On April 12, NASA's Fermi Gamma-ray Space Telescope ... > 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 -
Watching the Birth of a Sunspot

Plasmoids and Sheaths Mean Success or Failure for Solar Eruptions
April 18, 2011 — Our Sun experiences regular eruptions of material into space, but solar physicists still have difficulty in explaining why these dramatic events take place. Now scientists think they have the answer: ... > full story -
Solar Activity Heats Up: Sunspots Finally Return
April 15, 2011 — As 2011 unfolds, sunspots have returned and they are crackling with activity. On February 15 and again on March 9, Earth orbiting satellites detected a pair of "X-class" solar flares -- the most ... > full story -
Formaldehyde: Poison Could Have Set the Stage for the Origins of Life
April 4, 2011 — Formaldehyde, a poison and a common molecule throughout the universe, is likely the source of the solar system's organic carbon solids -- abundant in both comets and asteroids. Scientists have long ... > full story
