Many of the ice-encrusted moons orbiting the giant planets in the far reaches of our solar system are known to be geologically active. Quakes could be the source of the mysteriously smooth terrain on the moons circling Jupiter and Saturn, according to a new study led by a UArizona graduate student.  

UArizona astronomers have joined an international effort to study the aftermath of the brightest flash of gamma rays ever observed. Observations involving UArizona telescopes and instruments provide astronomers with a "cosmic lab" to study how massive stars die.

CatSat is a small satellite carrying a new communications concept – an inflatable antenna – into space. Led by UArizona students and supported by engineers from local aerospace companies, the project offers students a rare chance to get hands-on experience with spaceflight technology.

With NASA's James Webb Space Telescope, researchers are observing star formation in nearby galaxies with unprecedented resolution at infrared wavelengths.

University of Arizona space sciences activities generate more than $560 million every year for the local economy, according to an economic impact report delivered by Rounds Consulting Group.

NASA awarded nearly $3 million to the University of Arizona Kuiper Materials Imaging and Characterization Facility to support OSIRIS-REx sample science and much more.
