A star is born: The formation of H2 was crucial to the generation of the first stars and possibly the first galaxies. The rate of H2 generation by associative detachment (thick arrow in the scheme of the reactions of hydrogen in the early universe) has now been determined experimentally and may provide a more detailed understanding of the birth of the first stars.
