Magnetic Pumping Pushes Plasma Particles to High Energies

Nov. 5, 2018 — The solar wind is not a calm summer breeze. Instead, it is a roiling, chaotic mess of turbulence and waves. There is a lot of energy stored in this turbulence, so scientists have long thought that it ... read more

July 30, 2018 — An unlucky coincidence of space and Earth weather in early September 2017 caused radio blackouts for hours during critical hurricane emergency response efforts, according to a new study. The new ... read more

How Does the Sun's Rotational Cycle Influence Lightning Activity on Earth?

July 17, 2018 — A collaborative research team has taken the first steps to understanding how the sun's rotational cycle influences lightning activity. They found answers in an unusual source -- diaries dating ... read more

May 31, 2018 — A new study describes the first observations of the process of electron heating in Earth's bow shock. The researchers found that when the electrons in the solar wind encounter the bow shock, ... read more

The Case of the Relativistic Particles Solved With NASA Missions

May 29, 2018 — Encircling Earth are two enormous rings -- called the Van Allen radiation belts -- of highly energized ions and electrons. Various processes can accelerate these particles to relativistic speeds, ... read more

May 9, 2018 — Explorations in Earth's space environment by NASA's Magnetospheric Multiscale spacecraft have discovered a surprising new magnetic event in turbulent ... read more

Apr. 30, 2018 — A study of the most recent near-reversals of the Earth's magnetic field by an international team of researchers has found it is unlikely that such an event will take place anytime ... read more

New 3-D Measurements Improve Understanding of Geomagnetic Storm Hazards

Mar. 8, 2018 — Measurements of the three-dimensional structure of Earth, as opposed to the one-dimensional models typically used, can help scientists more accurately determine which areas of the United States are ... read more

Feb. 7, 2018 — Just one phenomenon may underlie all solar eruptions. Researchers have identified the presence of a confining 'cage' in which a magnetic rope forms, causing solar eruptions. It is the ... read more

Feb. 6, 2018 — The Sun might emit less radiation by mid-century, giving planet Earth a chance to warm a bit more slowly but not halt the trend of human-induced climate ... read more

Jan. 5, 2018 — Scientists have found a star that can help shed light on the physics underlying the solar dynamo. Researchers combined observations from the Kepler spacecraft with ground-based observations as far ... read more

Oct. 3, 2017 — Researchers used historic accounts of a rare red aurora over Kyoto, Japan, in the 18th century to support calculations of the strength of the associated magnetic storm. The September 1770 storm could ... read more

Solar Observer Created Key Sunspot Record

Oct. 2, 2017 — Few people have heard of Hisako Koyama, but the dedicated female solar observer, born in Tokyo in 1916, created one of the most important sunspot records of the past 400 ... read more

Aug. 18, 2017 — Scientists have forecast the corona of the sun during the upcoming eclipse. The findings shed light on what the eclipse of the sun might look like Aug. 21 when it will be visible across much of the ... read more

Aug. 10, 2017 — Three NASA-funded studies will use the Aug. 21 total solar eclipse as a ready-made experiment, courtesy of nature, to improve our understanding of the ionosphere and its relationship to the ... read more

Aug. 3, 2017 — The elemental composition of the Sun's hot atmosphere known as the 'corona' is strongly linked to the 11-year solar magnetic activity cycle, a team of scientists has revealed for the ... read more

July 3, 2017 — For upcoming climate model studies, scientists can use a new, significantly improved data set for solar forcing. Scientists have now published the details of the new reconstruction of this reference ... read more

May 18, 2017 — Scientists have explored the magnetic field in upper solar atmosphere by observing the polarization of ultraviolet light with the CLASP sounding rocket experiment during its 5-minute flight in space ... read more

May 17, 2017 — Human activities, like nuclear tests and radio transmissions, have been changing near-Earth space and weather, and have created artificial radiation belts, damaged satellites and induced ... read more

May 15, 2017 — The challenge of predicting space weather, which can cause issues with telecommunications and other satellite operations on Earth, requires a detailed understanding of the solar wind (a stream of ... read more
