New findings by UArizona researchers offer important insights into the evolution of the lunar interior, and potentially for planets such as Earth and Mars.

There were times when eclipses ended battles or cost astronomers their heads. Longtime UA astronomer Don McCarthy sheds some light on the celestial spectacle through history.

The goal of the six-day simulation, called Imagination 1, was to explore the value of art in space exploration and produce creative works inspired by the limitations and possibilities of life and culture beyond Earth.

The observations will help astronomers refine their theories about the processes involved in planet formation and shed light on what our sun did when it was very young.

A new view of the supermassive black hole at the center of the Milky Way obtained by the Event Horizon Telescope collaboration revealing its magnetic field structure suggests that the processes by which black holes feed and eject jets into their surroundings may be universal among black holes despite vast differences in size and mass.

The team behind the University of Arizona-led NASA mission to sample the asteroid Bennu joins the ranks of the Apollo 11 crew and Orville Wright to earn the Robert J. Collier Trophy.

The discovery, led by Haijiang Cai, an associate professor in the Department of Neuroscience, was observed in mice, but the findings could lead to human drug treatments.

University of Arizona researchers have modified the gut proteins of mosquito larvae, marking a significant advance in the fight against mosquito-borne diseases.

A University of Arizona-led study shines a spotlight on sulfur, a chemical element that, while all familiar, has proved surprisingly resistant to scientific efforts in probing its role in the origin of life.
