Earth's Space Storm Shield Offers Protection At A Price

Summary:
New observations from a NASA spacecraft reveal that a layer in the Earth's outer atmosphere acts like a heat shield by absorbing energy from space storms, which reduces their ability to heat the lower atmosphere. However, it imposes a heavy toll for its services by creating a billion-degree cloud of electrified gas, or plasma, that surrounds our planet. The plasma cloud is so ferociously hot, its particles act like radiation, occasionally disrupting satellites in mid to high orbits. This discovery from NASA's Imager for Magnetopause to Aurora Global Exploration (IMAGE) spacecraft confirms that the Earth actively participates in space storms.
