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.

A four-person crew sealed themselves in an air-tight pressurized habitat, called the Space Analog for the Moon and Mars, for six days to practice what it might be like to live on the surface of another celestial body.

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.

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.  

Join the Arizona Space Institute for a showcase of active and future projects related to space exploration. The symposium will explore this theme during plenary presentations on concept development and proposal facilitation, followed by flash talk presentations from participants. During the morning poster session and networking lunch, attendees will have an opportunity to discuss key themes and potential avenues of collaboration and influence that could be pursued beyond the symposium.

The Applied Research Building (ARB) is a highly specialized, one-of-a-kind, 89,000-square-foot facility that pairs new applied research capabilities with state-of-the-art equipment and technology and brings together several interdisciplinary university programs under one roof.

It will provide regionally unique capabilities for the university, allow for expansion of industry and advanced manufacturing partnerships, and turn research and discovery into practical, real-world solutions that produce societal impact.

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.
