A research team led by the U of A found that the brain of the extinct creature Jianfengia is very similar to that of living crustaceans, placing it in the ancestry of insects and crustaceans, not spiders and their relatives, as had been previously assumed.

Using a cutting-edge optics system developed at the University of Arizona, researchers have gotten a glimpse of what our solar system likely looked like during its infancy.

New observations that U of A astronomers helped make with the James Webb Space Telescope solidify previous hints of a giant planet orbiting the sun's closest neighbor.

Finely preserved brain features in a tiny marine arthropod fossil suggest that arachnids – spiders and their close kin – may have first evolved in the ocean rather than on land, challenging conventional wisdom.

The meteor impact that created one of Arizona's most recognizable landmarks and the wood and sediments found in a cave in the Grand Canyon are strikingly similar in age. A new study involving a U of A dendrochronologist suggests they could be related.

Despite its rich inventory of organic molecules, Saturn's largest moon may be able to support only a minuscule amount of biomass, if life exists there.

The U of A Center for Innovation is Arizona's leading business incubator network, helping science and technology startups in Southern Arizona and beyond to bring their ideas to market.

Between 2000 and 2023, glaciers collectively lost 7,211 billion tons of ice, contributing almost three quarters of an inch to global sea-level rise, a new study finds.

For the first time, one of the Giant Magellan Telescope's primary mirror segments, produced at the U of A Richard F. Caris Mirror Lab, has been integrated into a support structure that will maintain the mirror's shape once mounted on the telescope.

Researchers have discovered the most distant galaxy ever detected. The secrets it contains challenge previous assumptions about galactic evolution.
