<![CDATA[ Extreme exomoons with tidal heating and thick, hydrogen-rich atmospheres may be able to create billions of years of potentially habitable surface conditions. ]]>
Exomoons are natural satellites that orbit exoplanets. While no exomoon has been confirmed yet, their existence could provide insights into the habitability of exoplanets and the dynamics of planetary systems.
Tidal heating is the process by which the gravitational pull of a planet or moon causes internal friction and heating within another celestial body. This phenomenon can create geothermal energy, which may lead to conditions favorable for life, especially in icy worlds.
