By connecting radio telescopes across five continents into one Earth-sized virtual telescope, including two UA telescopes, astronomers managed to resolve the shadow of a supermassive black hole, a prediction of Einstein's General Theory of Relativity.
A UA geosciences undergraduate developed an innovative method of using ancient urine salts to reveal when humans in ancient Turkey began shifting from hunting to herding.
A UA team shows that evolution is driven by dependency on other species within ecological communities – testing a long-held idea of the late UA professor George Gaylord Simpson.
Two new studies by UA space scientists may bring into question the habitability of TRAPPIST-1 exoplanets, three of which are in the habitable zone of space.
