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.

A new Webb Space Telescope image of the bright, nearby star Fomalhaut reveals its planetary system with details never seen before, including nested concentric rings of dust. These belts most likely are carved by the gravitational forces produced by embedded, unseen planets.

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.
