Studying Solar Wind
June 29, 2011 — Scientists have measured oxygen isotopes in solar wind, captured by NASA's Genesis mission, to infer the isotopic composition of the sun, and, by inference, the solar system as a ... > full story -
Neutron Star Bites Off More Than It Can Chew
June 28, 2011 — The European Space Agency's XMM-Newton space observatory has watched a faint star flare up at X-ray wavelengths to almost 10 000 times its normal brightness. Astronomers believe the outburst was ... > full story -
Solar Wind Samples Give Insight Into Birth of Solar System
June 23, 2011 — The first oxygen and nitrogen isotopic measurements of the Sun are complete, demonstrating that they are very different from the same elements on Earth. These results were the top two priorities of ... > full story -
Scientists Prove Existence of 'Magnetic Ropes' That Cause Solar Storms
June 15, 2011 — Scientists discovered recently that a phenomenon called a giant magnetic rope is the cause of solar storms. Confirming the existence of this formation is a key first step in helping to mitigate the ... > full story -
When Jupiter Was in the Position of Mars
June 15, 2011 — A new scenario describing a key step in the formation of the solar system has been proposed by a French-American collaboration. According to this model, Jupiter migrated towards the Sun to the ... > 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 -
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
