  • The half of all normal matter in the universe that was unaccountably missing has finally been spotted. This matter--anything made from protons, neutrons and electrons--had never shown up in previous observations of galaxies and stars, even though calculations suggested it must exist. Two separate teams found the missing matter--comprising particles called baryons--that links galaxies through filaments of hot, diffuse gas. It differs from dark matter, the existence of which still remains a mystery.
