Astronomers have discovered a new type of stellar system that contains only young, blue stars. The structures are thought to be created when galaxies collide with hot gas in something of a galactic belly flop.

Weather watchers are invited to submit their monsoon predictions online in the Southwest Monsoon Fantasy Forecasts game. Created by UArizona climate researchers, the game draws inspiration from fantasy sports.

Extreme supergiant stars known as hypergiants are very rare, with only a few known to exist in the Milky Way. Astronomers have created a detailed, three-dimensional image of one dying hypergiant, providing new insights into what happens at the end of these rare stars' lives.

Arizona is ahead of the U.S. in reaching pre-pandemic job numbers, although the state's metropolitan areas have had varying levels of success, says economist George Hammond.

UArizona scientists took part in an international planetary defense exercise that used asteroid Apophis – a large, potentially hazardous asteroid – to test the planetary defense response chain.

A lunar rock collected during the 1971 Apollo 15 mission is on display until mid-August at the Alfie Norville Gem & Mineral Museum. It is the largest moon rock NASA loans to museums.

A new report indicates that startups and business generated through Tech Launch Arizona supported over 2,500 jobs and $561 million in labor income between fiscal years 2017 and 2021.

Construction has begun on a tall, hangar-like "high bay" facility, where researchers can build and test hardware for experiments and missions designed to fly at extremely high altitudes sometimes referred to as the "edge of space."

UArizona astrophysicists Feryal Özel and Dimitrios Psaltis identified Sagittarius A* as an ideal target black hole more than 20 years ago. They call it a "Goldilocks black hole," with an environment "just right" for capturing an image.

Snapping an image of a black hole is just the beginning, says researcher Chi-Kwan "CK" Chan. To really understand the image, it must be compared with black hole simulations. UArizona worked with partners to create the world's largest simulation library.
