When the OSIRIS-REx spacecraft delivers a sample from asteroid Bennu to Earth on Sept. 24, it will launch decades of scientific investigation. Mission principal investigator Dante Lauretta is most excited to shed light on the origins of life on Earth.

A new image of the massive El Gordo galaxy cluster, taken by NASA's James Webb Space Telescope, shows 62 distorted galaxies behind the cluster.

Everything must go smoothly when the OSIRIS-REx spacecraft releases its capsule full of pristine asteroid material over the Utah desert in September. Members of the mission team gathered at Lockheed Martin in Colorado to rehearse recovering the capsule and its precious cargo.

Astronomers have long been puzzled by spiral arms seen around some infant stars. UArizona researchers have discovered a young exoplanet that could explain this phenomenon and provide clues about planetary formation.

UArizona has signed a Space Act Agreement with NASA's Johnson Space Center that will allow the university to engage extensively in human spaceflight missions.

Using NASA's James Webb Space Telescope, astronomers have discovered a threadlike arrangement of 10 galaxies that existed just 830 million years after the Big Bang. The structure reveals clues and questions about the fundamental architecture of the universe.

The discovery of tiny salt grains in a sample from an asteroid provides strong evidence that liquid water may be more common in the solar system's largest asteroid population than previously thought.

NASA's James Webb Space Telescope has uncovered an unexpected bounty of full-fledged galaxies at a time when the universe was just getting started. Researchers learned that these galaxies went through bursts of star formation.

Regents Professors Marcia and George Rieke and UArizona alumna Jane Rigby were recognized for their accomplishments in astronomy and key contributions to the James Webb Space Telescope.

Scientists at the UArizona Lunar and Planetary Laboratory have created an online portal that allows members of the public to help discover asteroids hurtling through our solar system.
