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.

A book she found in a library when she was 10 inspired Melanie McKay-Cody to pursue a career studying Native American sign languages. Now, as a researcher in the U of A College of Education, she's one of the foremost experts at the intersection of Native and Deaf identity.

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.

U.S. Secretary of the Interior Deb Haaland has appointed University of Arizona's Michael Kotutwa Johnson to the Bureau of Land Management (BLM) Arizona Resource Advisory Council (RAC). He sees it as an opportunity to foster collaboration.

Pandora, a small satellite mission poised to provide in-depth study of at least 20 known planets orbiting distant stars to determine the composition of their atmospheres cleared an important milestone by completing the spacecraft bus, which acts as the spacecraft's "brains."

Astronomers have struggled with finding ultra-faint dwarf galaxies far enough from the Milky Way's influence, making these faintest galaxies in the cosmos difficult to study. 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.

High housing costs and ongoing financial instability make it difficult for many living in Tucson to cover basic expenses or manage unexpected emergencies, according to data collected by U of A students.

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.

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.
