Solar Eruption Sends Shockwaves Across Earth, Moon, and Mars

A massive coronal mass ejection from the sun on October 28, 2021, was so significant that it affected Earth, the moon, and Mars simultaneously. This rare "ground level enhancement" event allowed energetic solar particles to reach the surfaces of these celestial bodies. While Earth's magnetic field protected us from the majority of the particles, the moon and Mars, lacking their own magnetic fields, were more vulnerable. Understanding these solar events is crucial for protecting astronauts during future missions to the moon and beyond, as radiation exposure can have severe health consequences.
