NASA / Revolutions in Understanding the Ionosphere, Earth’s Interface to Space

Scientists from NASA and three universities have presented new discoveries about the way heat and energy move and manifest in the ionosphere, a region of Earth’s atmosphere that reacts to changes from both space above and Earth below.

Far above Earth’s surface, within the tenuous upper atmosphere, is a sea of particles that have been split into positive and negative ions by the sun’s harsh ultraviolet radiation. Called the ionosphere, this is Earth’s interface to space, the area where Earth’s neutral atmosphere and terrestrial weather give way to the space environment that dominates most of the rest of the universe – an environment that hosts charged particles and a complex system of electric and magnetic fields. The ionosphere is both shaped by waves from the atmosphere below and uniquely responsive to the changing conditions in space, conveying such space weather into observable, Earth-effective phenomena – creating the aurora, disrupting communications signals, and sometimes causing satellite problems…
