New research suggests that 2 to 3 million years ago, Earth was exposed to a dense interstellar cloud due to a collision with the sun's protective bubble. This event may have impacted the planet's climate and evolution, potentially exposing it to radioactive particles for thousands of years.

2 to 3 million years ago, researchers think the heliosphere that surrounds the solar system crashed into a galactic cloud. @jameswoodford1 says this could've impacted evolution, leaving Earth exposed to interstellar radiation for 10 thousand years. https://t.co/ItNBRwVpzc
"heliosphere was exposed to a much denser interstellar cloud 2-3 million years ago. … Earth would have been outside the heliosphere & directly exposed to the interstellar environment … possibly for as long as 10K years" https://t.co/7qyvHyjtjN https://t.co/odLHOjGtK1

🌍 New research led by BU suggests 2M years ago, the solar system crossed an interstellar cloud, possibly affecting Earth's climate. This event might have exposed the planet to radioactive particles, providing new perspectives on life's evolution. ➡️ https://t.co/S2DDkvmto7 https://t.co/hfqwD7Ht6O
A collision between the sun's protective bubble and a dense interstellar cloud 2 million to 3 million years ago exposed Earth to an interstellar medium, which probably shaped our climate and evolution. https://t.co/QpikSus4uw
A possible direct exposure of the Earth to the cold dense interstellar medium 2–3 Myr ago [with a possible impact on human evolution?] https://t.co/e1zlIaNskh
