Core Insights - The Parker Solar Probe has achieved the first direct observation of magnetic reconnection in the solar atmosphere, confirming a theory proposed 70 years ago, which enhances the ability to predict solar storms [1][2] - Magnetic reconnection is a process where magnetic field lines break and reconnect, releasing significant magnetic energy, which can lead to solar flares and coronal mass ejections [1] - The successful observation was made possible by the Parker Solar Probe's close approach to the Sun and collaboration with the European Space Agency's solar orbiter [1][2] Group 1 - The Parker Solar Probe, launched in 2018, is the only spacecraft capable of entering the solar upper atmosphere for direct measurements [1] - The probe captured a significant solar eruption on September 6, 2022, allowing for high-resolution imaging and sampling of plasma and magnetic field characteristics [1] - This breakthrough enables scientists to better understand the mechanisms of solar energy transfer and particle acceleration, improving the accuracy of solar activity predictions [2]

Core Insights - The Parker Solar Probe has successfully completed another close flyby of the Sun, reaching a distance of approximately 6.2 million kilometers from the solar surface, and traveling at a speed of about 687,000 kilometers per hour, setting new distance records since late last year [1][3] - The probe aims to gather data on the solar atmosphere and solar wind, addressing scientific questions regarding the high temperature of the corona, the acceleration of solar wind, and the origins of high-energy solar particles [2][4] Group 1: Parker Solar Probe's Mission and Achievements - Since its launch in August 2018, the Parker Solar Probe has conducted 24 close flybys of the Sun, leading to significant discoveries such as the magnetic field reversal structure of solar wind and the confirmation of a dust-free zone near the Sun [3] - The probe is equipped with four advanced instruments designed to measure various physical parameters of solar wind and capture images of solar disturbances, ensuring its functionality under extreme solar radiation through a specially designed thermal protection system [2][3] Group 2: Solar Activity and Its Implications - The Sun exhibits an approximately 11-year cycle of activity, currently in its 25th solar cycle, characterized by an increase in sunspot numbers and complex magnetic structures, leading to frequent solar flares and coronal mass ejections that significantly impact the Earth's space environment [3][4] - Other international missions, including the European Solar Orbiter and China's Kuafu-1 and Xihe satellites, are also observing solar activity to enhance understanding of solar phenomena and improve predictive capabilities regarding solar storms, which can affect critical infrastructure on Earth [4]

当多个CME相互碰撞时，它们的运行轨迹与强度都可能发生显著变化。这种合并还可能加速带电 粒子，改变磁场结构，使其对宇航员、卫星以及地面技术设施造成更严重威胁。"帕克"探测器的近距离 观察有助于科研人员更好地预测并应对这种空间环境效应。 太阳风是一种持续不断的带电粒子流，会穿越整个太阳系，对地球造成广泛影响。这些图像首次清 晰展示了太阳风从日冕释放后的演化过程，以及太阳磁场由北向南反转的关键边界，即"日球电流片"。 这些图像还首次以高分辨率捕捉到多个日冕物质抛射（CME）事件的相互碰撞过程。CME是太阳 喷发出的高速带电粒子团，是太空天气的主要驱动因素。"帕克"探测器显示，多个CME在空间中"叠 加"。 "帕克"探测器于2018年发射升空，任务是深入研究太阳外层大气——日冕。去年12月24日，它飞至 距离太阳表面约610万公里处，这是人类探测器首次进入太阳大气内部运行。此次飞行中，"帕克"利用 其宽视场成像仪拍摄了大量高清图像，记录了太阳日冕结构及太阳风的释放过程。 原标题："帕克"探测器拍到距太阳最近的图像 科技日报讯 （记者张佳欣）美国国家航空航天局（NASA）7月10日公布了一组震撼图像，即来 自"帕克" ...
