The Moon May Have Once Been Habitable! SciShow News

The video explores the potential past habitability of the Moon, highlighting that while the Moon is currently inhospitable, it may have once had conditions suitable for life. The challenges of sustaining life on the Moon today include extreme temperatures and lack of atmosphere. The video also discusses the early conditions of the Moon, such as volcanic activity and a magnetic field, which might have supported life. Additionally, it examines the Sun's early activity, revealing that it was more active in its youth, impacting the solar system's formation and evolution.
