News Image U of A astronomers capture unprecedented view of supermassive black hole in action Jan. 17, 2025 U of A astronomers have now produced the highest resolution direct images ever taken of a supermassive black hole in the infrared, using the Large Binocular Telescope Interferometer. Read more at University of Arizona News Image Large and small galaxies may grow in ways more similar than expected Jan. 16, 2025 Galaxies like the Milky Way grow by merging with smaller galaxies over billions of years, unlike dwarf galaxies, which have long been thought to lack the heft to attract mass and grow in the same way. New observations challenge this view, suggesting that even dwarf galaxies can accrete mass from other small galaxies.

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.

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.

Many are surrounded by protoplanetary disks – swirling "pancakes" of hot gas and dust, from which planets form.
