Oct. 22, 2020 —Earth's magnetic fields typically switch every 200 to 300 millennia. Yet, the planet has remained steady for more than twice that now, with the last magnetic reversal occurring about 773,000 ...
Feb. 16, 2021 —A small sub-alpine lake in western Tasmania has helped establish that 41,000 years ago Australia experienced the Laschamp geomagnetic excursion and that Tasmanian, Aboriginals, would've seen ...
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 ...
Mar. 2, 2021 —Analysis of observations made by satellites in 2014 has revealed a long-lasting 'space hurricane' -- a swirling mass of plasma several hundred kilometers above the North Pole, raining ...
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 ...
June 29, 2020 —The history of our planet has been written, among other things, in the periodic reversal of its magnetic poles. Scientists propose a new means of reading this historic record: in ice. Their findings ...
May 23, 2022 —A small computer aboard the International Space Station programmed by Portuguese students enables measurements as part of Raspberry Pi Foundation's Astro Pi ...
Feb. 18, 2021 —地球磁场的临时故障42,000 years ago sparked major climate shifts that led to global environmental change and mass extinctions, a new international study ...
Aug. 17, 2021 —Violent activity on our Sun leads to some of the most extreme space weather events on Earth, impacting systems such as satellites, communications systems, power distribution and aviation. The roughly ...
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 ...
