March 5, 2024 James Webb Space Telescope captures the end of planet formation How much time do planets have to form from a swirling disk of gas and dust around a star? A new University of Arizona-led study gives scientists a better idea of how our own solar system came to be.
Jan. 29, 2024 Webb Telescope reveals stunning structures in nearby spiral galaxies New images taken with the James Webb Space Telescope reveal intricate, never-before-seen structures and features hidden in visible light. The insights will help astronomers better understand the history of the Milky Way.
Dec. 18, 2023 Asteroids, athletics and 'America the Beautiful': The top stories of 2023 From delivering a historic asteroid sample to setting a university record in Fulbright Scholars, the University of Arizona celebrated several newsmaking events in 2023.
Aug. 2, 2023 'Cosmic lens' reveals distant galaxies and helps astronomers better understand dark matter 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.
July 6, 2023 Astronomers discover elusive planet responsible for spiral arms around its star 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.
June 29, 2023 UArizona astronomers identify the earliest strands of the cosmic web 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.
June 5, 2023 Infant universe teemed with full-fledged galaxies crackling with bursts of star formation 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.
May 24, 2023 NASA honors UArizona Regents Professors, alumna for contributions to space exploration and astronomy 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.
May 8, 2023 Nearby planetary system seen in breathtaking detail 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.
