NASA-funded research indicates that Earth’s climate has been significantly influenced by the Sun's journey through dense regions of the Milky Way and its youthful superflares, potentially explaining ancient ice ages and early warming periods.

These findings suggest that when the young Sun was less luminous, these solar events could have provided enough heat to maintain liquid water on Earth, crucial for life’s development.

Understanding these historical influences helps scientists predict future climate changes by considering external cosmic factors alongside internal planetary dynamics.
