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.

As a sizable asteroid makes a close pass by Earth, a team of UArizona students is ready to observe the action to practice and test procedures that could be useful in mitigating an impending asteroid impact in the future.

Using the James Webb Space Telescope, astronomers observed detailed features, including roiling clouds of dust, in the atmosphere of a brown dwarf planet 40 light-years away.

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.

The mystery of whether microbial alien life might inhabit Enceladus, one of Saturn's 83 moons, could be solved by an orbiting space probe, according to a UArizona-led study.

Black holes are surrounded by an invisible layer that swallows every bit of evidence about their past. Researchers are now using machine learning and supercomputers to reconstruct the growth histories of black holes.

Less than a year after the James Webb Space Telescope's Christmas Day launch in 2021, scientists have captured images of the most distant galaxies ever seen.

Thanks to the James Webb Space Telescope, scientists have identified a "mystery molecule" that previously stumped astronomers. They've also gained insights needed to interpret potential signs of habitability on other exoplanets.
