While pursuing her doctorate, Burçin Mutlu-Pakdil discovered an especially rare, double-ringed galaxy. The discovery drew international attention, and the galaxy is now known as Burçin's galaxy.
An international research team led by UA researchers found that planet warming drove major changes in vegetation and future warming may drive similarly dramatic changes around the world.
Astronomers have detected the most-distant galactic "wind" of molecules ever observed, seen when the universe was only one billion years old.
UA researchers were able to access untapped clues about the monsoon's activity during the last ice age, with implications that may help predict the monsoon's future.

UA Science: A Place of Discovery and Innovation

Joaquin Ruiz, DeanThe University of Arizona College of Science brings together globally prominent faculty in disciplines at the core of scientific inquiry and education. One of the largest colleges at the University of Arizona, we are a nexus of award-winning programs that encourage both independent and collaborative-driven research. Our academic departments, schools and research units encompass the range of physical, mathematical, environmental, cognitive and life sciences. UA Science is among the most powerful and prolific academic research centers in the world, recognized and rewarded for the unparalleled caliber of our achievements. With over 7,500 undergraduate and graduate students, we are an integrative learning institution, where accomplished faculty and next-generation scientists engage side-by-side in groundbreaking research. Our scientists and students also share their knowledge with the local and broader community through extensive outreach and public service initiatives. Our mission is to encourage the aggressive pursuit of research excellence, to support novel teaching and outreach programs and to create economic opportunities for our community.

Declining Snowpack over Western US Mapped at a Finer Scale
UA-led researchers mapped changes in snow from 1982 to 2016 over the contiguous U.S. and found parts of the West have had a 41 percent reduction in the yearly maximum snow mass.
Bennu, Burials and (Queen) Bees: UA's Top Stories of 2018
Does an asteroid hold the clues on the origins of the solar system? Does office layout directly impact health and well-being? Does music strengthen familial bonds? UA research explored these questions and much more in 2018.
UA-Led OSIRIS-REx Discovers Water on Asteroid Bennu
Observations made by the spacecraft during its approach of Bennu reveal that the asteroid interacted with water in its early history and is an excellent specimen for the mission, which is slated to return a sample of surface material to Earth in 2023.
UA Undergrad Works to ID OSIRIS-REx Touchdown Site
Systems engineering and mathematics double major Keara Burke is helping NASA's OSIRIS-REx spacecraft find the perfect place to collect samples on the asteroid Bennu.
Unknown Treasure Trove of Planets Found Hiding in Dust
A survey of protoplanetary disks surrounding young stars in the Taurus star-forming region turned up a number of disks with features suggesting nascent planets.
