WebbThe Ionospheric Connection Explorer, or ICON, is a new NASA Explorer mission that will explore the boundary between Earth and space to understand the physical connection between our world and our space environment. This connection is made in the ionosphere, which has long been known to exhibit variability associated with the sun and solar wind. … WebbThe existence of expanded thermospheres in hot gas planets was first confirmed in the exoplanet HD209458b, where Vidal-Madjar et al. (2003) found absorption of up to 15% in the line wings of the stellar hydrogen Ly line during the transit of the hot Jupiter. Since the optical transit depth in this system is only
