HiRISE, a U of A-led Mars imaging camera aboard NASA's Mars Reconnaissance Orbiter, found itself closer than any other imaging tool to comet 3I/ATLAS as it passed through the solar system.

A new technique helps artificial intelligence systems recognize when they don't know the answer, addressing "wrong-but-confident" AI outputs across science and society.

University of Arizona telescopes helped capture dramatic changes in a supermassive black hole's environment over the course of four years.

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.

The first images from the Vera C. Rubin Observatory mark a proud milestone for the University of Arizona, whose Richard F. Caris Mirror Lab is the only facility in the world capable of crafting the telescope's unique mirror.

Built with mirrors manufactured by the University of Arizona, one of the world's largest optical telescopes clears key milestone toward U.S. federal construction support.

New observations of 30 planet-forming disks – the birthplaces of planets around stars – reveal in greater detail than ever how gas and dust behave over time and shape the evolution of exoplanet systems.

Astronomers have identified massive, dense star factories, unlike any found in the Milky Way, providing a rare glimpse into processes shaping galaxies in the very early universe.

NASA has selected Rocket Lab USA Inc. to launch the agency's Aspera mission early next year. Led and managed by the U of A, Aspera will study galaxy evolution through observation of ultraviolet light.
