Eleven plaques have been installed across campus to show the relative sizes and distances of solar system objects. Zarah Brown, a doctoral student at the Lunar and Planetary Laboratory, led the project to make space science accessible to people of all ages.

A new image of the massive El Gordo galaxy cluster, taken by NASA's James Webb Space Telescope, shows 62 distorted galaxies behind the cluster.

Astronomers have long been puzzled by spiral arms seen around some infant stars. UArizona researchers have discovered a young exoplanet that could explain this phenomenon and provide clues about planetary formation.

Using NASA's James Webb Space Telescope, astronomers have discovered a threadlike arrangement of 10 galaxies that existed just 830 million years after the Big Bang. The structure reveals clues and questions about the fundamental architecture of the universe.

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.
