Dec. 8, 2014 — Scientists now have an observational framework to help predict solar weather. Being able to predict such events is important because a powerful direct hit by a coronal mass ejection (CME) is like a ... read more

Oct. 6, 2014 — When the supersonic solar wind hits the Earth's magnetic field, a powerful electrical connection occurs with Earth's field, generating millions of amperes of current that drive the dazzling ... read more

Sep. 23, 2014 — Strong solar flares can bring down communications and power grids on Earth. By demonstrating how these gigantic eruptions are caused, physicists are laying the foundations for future predictions. The ... read more

Geomagnetic Storm Mystery Solved: How Magnetic Energy Turns Into Particle Energy

Sep. 10, 2014 — Magnetic reconnection can trigger geomagnetic storms that disrupt cell phone service, damage satellites and black out power grids. But how reconnection, in which the magnetic field lines in plasma ... read more

Magnetic Substorms May Sometimes Be Driven by Different Process Than Generally Thought

Sep. 2, 2014 — Magnetic substorms, the disruptions in geomagnetic activity that cause brightening of aurora, may sometimes be driven by a different process than generally thought, a new study ... read more

Aug. 20, 2014 — On the evening of Aug. 20, 2014, the International Space Station was flying past North America when it flew over the dazzling, green blue lights of an aurora. On board, astronaut Reid Wiseman ... read more

Aug. 18, 2014 — A new study has, for the first time, reconstructed solar activity during the last ice age. The study shows that the regional climate is influenced by the sun and offers opportunities to better ... read more

July 8, 2014 — Researchers have measured the highest level of ultraviolet radiation ever recorded on Earth's surface. The extraordinary UV fluxes, observed in the Bolivian Andes only 1,500 miles from the ... read more

June 24, 2014 — The solar array that will provide power to NOAA's GOES-R satellite has been tested, approved and shipped to a facility where it will be incorporated on the spacecraft. The five sections of the ... read more

June 9, 2014 — Space is not empty. A wind of charged particles blows outwards from the Sun, carrying a magnetic field with it. Sometimes this solar wind can break through the Earth’s magnetic field. Researchers ... read more

Investigating Unusual Three-Ribbon Solar Flares With Extreme High Resolution

June 3, 2014 — The 1.6 meter telescope at Big Bear Solar Observatory in California has given researchers unparalleled capability for investigating phenomena such as solar flares. The BBSO instrument is the most ... read more

May 14, 2014 — Scientists have discovered new evidence to suggest that lightning on Earth is triggered not only by cosmic rays from space, but also by energetic particles from the sun. Researchers found a link ... read more

Apr. 24, 2014 — A NASA scientist is launching a one-to-two-year pilot project this summer that takes advantage of U.S. high-voltage power transmission lines to measure a phenomenon that has caused widespread power ... read more

Mar. 19, 2014 — Scientists have discovered a new, persistent structure in one of two radiation belts surrounding Earth. NASA's twin Van Allen Probes spacecraft have shown that high-energy electrons in the inner ... read more

Mar. 18, 2014 — On July 23, 2012, a huge magnetic storm propelled by two nearly simultaneous coronal mass ejections on the sun plowed through Earth's orbit. Luckily, Earth was on the other side of the sun at ... read more

Mar. 6, 2014 — Scientists have identified a plasma plume that naturally protects the Earth against solar storms. Earth's magnetic field, or magnetosphere, stretches from the planet's core out into space, ... read more

'Standing on a Comet': Rosetta Mission Will Contribute to Space Weather Research

Jan. 16, 2014 — A comet-bound spacecraft that's been in sleep mode for more than two years is scheduled to wake up on the morning of Jan. 20 -— beginning the home stretch of its decade-long journey to a ... read more

Dec. 18, 2013 — New research resolves decades of scientific controversy over the origin of ultra-relativistic electrons in the Earth's near space environment, and is likely to influence our understanding of ... read more

2012 Solar Storm Points Up Need for Society to Prepare

Dec. 9, 2013 — A massive ejection of material from the sun initially traveling at over 7 million miles per hour that narrowly missed Earth last year is an event solar scientists hope will open the eyes of ... read more

Unique Model Simulates Electron Environment in Space at 36000 Km Above the Earth

Dec. 9, 2013 — A spacecraft at near-Earth orbit is continuously bombarded by charged particles. Scientists have now developed a unique model that simulates electron environment in the near-Earth ... read more
