多个航天器讲述了一个巨大太阳风暴的故事
2021年4月17日，对太阳来说是平凡的一天，直到一道明亮的光闪爆发，巨大的太阳物质云从我们的恒星中喷涌而出。太阳的这种爆发并不罕见，但这一次的爆发范围异常广泛，它以接近光速的速度抛射高速质子和电子，击中了内太阳系多个航天器。
SOHO卫星拍摄的日珥
2022年1月30日 A Solar Prominence from SOHO Image Credit: NASA, ESA, SOHO-EIT Consortium Explanation: How can gas float above the Sun? Twisted magnetic fields arching from the solar surface can trap ionized gas, suspending it in huge looping structures. These majestic plasma arches are seen as prominences above the solar limb. In 1999, this dramatic and detailed image was recorded by the Extreme ultraviolet Image Telescope (EIT) on board the space-based SOHO observatory in the light emitted by ionized Helium. It shows hot plasma escaping into space as a fiery prominence breaks free from magnetic confinement a hundred thousand kilometers above the Sun. These awesome events bear watching as they can affect communications and power systems over 100 million kilometers away on planet Earth. In late…
