Group 1: Solar Activity and Space Weather Monitoring - A significant geomagnetic storm occurred from June 1 to June 2, triggered by solar activity on May 31, with a duration of 6 hours [1] - The primary cause of this geomagnetic activity was coronal mass ejection, a major form of solar eruption [1] - Monitoring and forecasting space weather is crucial for the stable operation of satellites, communication, navigation, and power systems [1] Group 2: Dark Matter Research - Researchers from the Xinjiang Astronomical Observatory and the State University of Rio de Janeiro discovered special effects induced by dark photons within the framework of Einstein-Cartan-Horava gravity theory [2] - The Barbero-Immirzi (BI) parameter, a key parameter in loop quantum gravity theory, was measured, which may influence the generation and propagation of gravitational waves [2] - The study of the BI parameter could provide insights into the potential connections between dark matter and dark energy, offering new approaches to understanding these cosmic mysteries [2] Group 3: Planetary Exploration - The Tianwen-2 probe was successfully launched, with the primary mission to explore and sample asteroid 2016 HO3, followed by scientific exploration of main belt comet 311P [3] - The mission is expected to reach distances between 150 million to 500 million kilometers from Earth, aiming to expand scientific knowledge of small celestial bodies [3]
