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.
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.
On April 23, 1923, the university celebrated a new, 36-inch telescope that would kick off major astronomical research. Steward Observatory will be rededicated this weekend in honor of its 100-year anniversary.
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.
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.
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.
With NASA's James Webb Space Telescope, researchers are observing star formation in nearby galaxies with unprecedented resolution at infrared wavelengths.
