Binary star systems, home to over half the galaxy's stars, present unique challenges for planetary habitability through variable radiation and complex gravitational dynamics, yet astronomers are discovering dozens of circumbinary planets and exploring whether life could adapt to these chaotic dual-sun environments.
New research suggests the Fermi paradox might have a simple answer: civilizations plateau at modest technology levels due to natural limits, making them nearly invisible. The silence isn't a mystery but the logical outcome of cosmic sustainability.
Carbonaceous chondrite meteorites delivered Earth's oceans and the molecular building blocks of life through billions of years of asteroid bombardment, with isotopic fingerprints proving these space rocks carried water identical to our seas.
