Alien Visitor From Beyond the Solar System Might Have Cooled Earth

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.

Supernovae's Potential Role in Earth's Past and Future Climate Changes

Research suggests supernovas may have caused significant climate changes on Earth in the past by damaging the ozone layer and affecting greenhouse gases, with potential implications for future events as nearby stars like Betelgeuse go supernova. Evidence from space telescopes and tree rings supports this theory, highlighting the importance of understanding supernova impacts on our planet.
