Study Reveals Ancient Interstellar Cloud's Impact on Earth's Climate

Astrophysicists find evidence of a dense interstellar cloud compressing the heliosphere, exposing Earth to cosmic radiation two million years ago.

New research suggests a dense interstellar cloud affected Earth's climate by compressing the heliosphere.
This event exposed Earth to increased cosmic radiation, supported by geological isotope evidence.
The study indicates the sun's movement through space significantly influences Earth's environmental history.
Sophisticated models traced the sun's position and the Local Ribbon of Cold Clouds system two million years ago.
Future research aims to explore the sun's past trajectory to understand more about interstellar influences on Earth.
