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 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.

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.

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.

The Alfie Norville Gem & Mineral Museum is now one of only three places in the world where the public can see a piece of the asteroid Bennu, collected during NASA's University of Arizona-led OSIRIS-REx mission.

How much time do planets have to form from a swirling disk of gas and dust around a star? A new University of Arizona-led study gives scientists a better idea of how our own solar system came to be.

Dr. Klein's research focuses on studying fundamental plasma phenomena that governs the dynamics of systems within our heliosphere as well as more distant astrophysical bodies.
