For billions of years, earth has served as the only home for life, shielded by a thick atmosphere and a protective magnetic field. However, our planet are not vacuums; they orbit within a crowded space. While space has historically been viewed as silent, modern astrophysics reviews it to be an electromagnetic threat. From the immediate destruction of global technology by solar storms to the existential risks posed by near- earth objects and beep – space radiations, our survival depends on our ability to monitor, predict, and eventually mitigate this celestial hazard.{D. Perna, 2013}
Here are a list of the 10 most significant threats originating beyond our atmosphere, evolving their probability, potential impacts and the current state of our planetary defense system.
TOP 10 THREATS FROM SPACE.
1.Earth’s orbit is becoming filled with old rocket parts and broken satellites. If they crash into each other, they could put our satellites at risk.
2. Huge space rocks could hit Earth and cause worldwide destruction.
3.The Sun can release massive bursts of energy that can cause powerful magnetic storms.
4. Extremely powerful energy release of radiation from exploding stars could destroy Earth’s ozone layer if they happen close enough, leaving life exposed to harmful UV rays.
5. If a massive star explodes, the radiation could damage our atmosphere and ozone layer. {M.R. Migaudz, 2020}
6. Far in the future, the Sun will become a more threat posing star near us.
7. A passing star can disturb the outer solar system.
8. High-energy particles from space can harm astronauts and damage electronics.
9. Fast-moving rocks from outside our solar system travel at extreme speeds and follow unpredictable paths.
10. Rocket launches and burning satellites release soot and chemicals into the atmosphere, which may affect our ozone layer. {P.K.Kallender, 2014}
