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.

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.

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."
