The Simple Molecule Behind Our Complex Universe

Molecular hydrogen (H2) played a crucial role in the formation of the universe by cooling gas clouds, allowing gravity to form stars and galaxies. Despite its abundance, H2 was only detected in space in 1970 using UV-sensitive technology. Today, H2 continues to influence star formation and the evolution of the universe, providing insights into where new stars are born and their characteristics.
