Understanding extreme solar particle phenomena

Recent research suggests that “extreme solar particle events”, which are extremely rare but can have a large impact on Earth, can be dangerous. These events involve the sun launching protons into space, which happen about once every thousand years. The latest recorded occurrence is in 993 CE. Once they reach Earth, they become a major threat.

Understanding extreme solar particle phenomena

When the sun sends many protons into space, it is called an extreme solar particle phenomenon or solar storm. These solar events are more powerful than regular solar flares and can cause more damage to the Earth.

Effects on the ozone layer

One of the biggest dangers is that solar particle phenomena can damage the Earth’s ozone layer. This layer acts as a shield to protect you by blocking and absorbing most of the sun’s harmful ultraviolet radiation. If the ozone layer is damaged, the earth’s surface will be exposed to more UV light.

Potential human health hazards

Getting too much UV rays can be very bad for your health. Experts for holes in the ozone layer, Alan Cooper and Pavel Arsenovic, say higher UV levels are more likely to cause skin cancer and other DNA damage. Depending on how bad the solar event was and the state of the Earth’s magnetic field, these conditions can last for a long time, exacerbating the effects.

Long-term effects and global implications

Research has shown that if a very strong solar particle event occurs when the Earth’s magnetic field is weak, the effects can be much worse and last longer. UV exposure can increase by 25%, and sun-induced DNA damage by 50%. This effect can last up to six years.

Who studied the effects of these events?

Alan Cooper of Charles Sturt University and Pavel Arsenovic of the University of Natural Resources and Life Sciences conducted the new study. By studying these solar phenomena and their effects, scientists have been emphasizing how important it is to monitor solar activity in order to effectively protect the world from potential threats.
