Ahead of Sunday's sample delivery, learn about the asteroid, the spacecraft and the people starring in the historic OSIRIS-REx mission, which will launch decades of scientific research and could help explain the origins of the solar system and life itself.

Eleven plaques have been installed across campus to show the relative sizes and distances of solar system objects. Zarah Brown, a doctoral student at the Lunar and Planetary Laboratory, led the project to make space science accessible to people of all ages.

Members of NASA's UArizona-led OSIRIS-REx mission completed one last dress rehersal before the spacecraft delivers a sample from asteroid Bennu to the Utah desert on Sept. 24.

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.

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.

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.

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.
