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.

Astronomers have discovered an enormous cloud of gas and dust, containing the fundamental building block of stars and planets. Dubbed Eos, the molecular cloud is one of the largest single structures in the sky.

Analyzing radiocarbon in tree-ring samples, scientists have created the most detailed record yet of solar activity during the first millennium B.C.E.

A mission to probe the mysteries of the faint universe made a major stride toward launch after the completion of the spacecraft "bus" assembly.

A combination of cosmic processes shapes the formation of one of the most common types of planets outside of our solar system, a new study involving U of A researchers finds.

NASA's newly launched SPHEREx mission will use software developed at the Arizona Cosmology Lab to analyze data and help astronomers understand what happened in the first trillionth of a second after the Big Bang.
