Oct. 30, 2023 Large geomagnetic storms disrupt radio signals and GPS. Now, researchers have identified the previous underestimated role of the ionosphere, a region of Earth's upper atmosphere that contains a ...
Mar. 31, 2022 An international team of scientists has proved that Mercury, our solar system's smallest planet, has geomagnetic storms similar to those on Earth. Their finding, a first, answers the question of ...
Dec. 9, 2021 Last year, scientists looked on as a star called EK Draconis ejected a massive burst of energy and charged particles many times more powerful than anything recorded on Earth's sun. Such ...
Aug. 5, 2021 Understanding the Sun's magnetic dynamo could help predict solar weather, such as potentially dangerous geothermal storms, solar flares and sunspots. Mathematicians have proposed a new model of ...
Dec. 1, 2023 An international multidisciplinary team consisting of solar physicists, geophysicists, and historians from nine countries analysed observations of an extreme solar-terrestrial storm reported in ...
June 7, 2023 Researchers used data from NASA's Parker Solar Probe to explain how the solar wind is capable of surpassing speeds of 1 million miles per hour. They discovered that the energy released from the ...
Jan. 26, 2022 Through analysis of ice cores from Greenland and Antarctica, a research team has found evidence of an extreme solar storm that occurred about 9,200 years ago. What puzzles the researchers is that the ...
May 20, 2021 Although patterns in the timing of moderate space weather events are known, the most extreme and dangerous events were thought to be random in their timing. This study found for the first time that ...
Mar. 24, 2022 The further we move away from a heat source, the cooler the air gets. Bizarrely, the same can't be said for the surface of the Sun, but scientists may have just explained a key part of ...
June 8, 2021 The spectacularly colorful aurora borealis -- or northern lights -- that fills the sky in high-latitude regions has fascinated people for thousands of years. Now, a team of scientists has resolved ...
