Alien Visitor From Beyond the Solar System Might Have Cooled Earth

Originally Published 5 months ago — by The Daily Galaxy

A 2024 study suggests that millions of years ago, the solar system's passage through a dense interstellar cloud compressed the heliosphere, exposing Earth to cosmic particles, which may have caused climate cooling and influenced human evolution. Future encounters with similar clouds are possible, highlighting the importance of space research.

Extraterrestrial Encounter Could Have Significantly Cooled Earth

Originally Published 5 months ago — by IFLScience

A study suggests that our solar system's passage through dense interstellar clouds may have contracted the heliosphere, allowing interstellar material to reach Earth and potentially causing significant climate cooling in the past, with evidence found in geological isotopes. This process could have influenced Earth's climate and even human evolution.
