Three newly discovered dwarf galaxies in an isolated region of space show evidence of star formation being cut short by events in the early universe.

The grant from the National Institute for Occupational Safety and Health will support U of A researchers' work to improve safety and productivity in the mining industry.

Billions of years ago, two icy worlds collided. Rather than destroying each other in a cosmic catastrophe, they spun together like a celestial snowman, finally separating but remaining forever linked in orbit. This is how Pluto and its largest moon, Charon, originated, a U of A study finds.

Taking advantage of a cosmic "double lens," astronomers resolved more than 40 individual stars in a galaxy so far away its light dates back to when the universe was only half its present age.

From canine companionship to intergalactic intrigue, U of A research, scholarship and expertise generated news around the world in 2024.

The U of A delivered $955 million in total research activity last year, ranking among the top 20 public research institutions and remaining No. 1 in astronomy and astrophysics. University officials project research activity exceeded $1 billion in fiscal year 2024 and are submitting the data to the National Science Foundation for review. The official number will be confirmed in the fall.

Nearly all living organisms use the same genetic code, the building blocks of life. A new study suggests conventional wisdom about how the code evolved is likely flawed.

The Burn Period Tracker tool provides real-time information on the number of hours per day that relative humidity is less than or equal to 20% – a metric informally known as the "burn period." The tool has been has been widely adopted by fire managers across the Southwest.

Shibin Jiang in optical sciences and Abhijit Mahalanobis in electrical and computer engineering were recognized for developing influential inventions in their fields.

U of A geoscientists are leading a $12 million feasibility study to characterize geologic locations suitable for carbon dioxide storage in the Harquahala basin west of Phoenix.
