Every year, three Buchalter Prizes are awarded in recognition of ground-breaking work in cosmology with the potential to produce a breakthrough advance in our understanding of how the Universe works, particularly by substantially extending or challenging currently-accepted models. The first, second, and third prize come with a prize money of $10,000, $5,000, and $2,500 respectively. The winners are typically announced in the January meeting of the American Astronomical Society (AAS), placing it de facto among the annual AAS prizes.
