Snapping an image of a black hole is just the beginning, says researcher Chi-Kwan "CK" Chan. To really understand the image, it must be compared with black hole simulations. UArizona worked with partners to create the world's largest simulation library.
After years of anticipation, the international Event Horizon Telescope Collaboration presented the first image of the black hole located at the center of our own Milky Way galaxy, called Sagittarius A*. Scientists had previously suggested the presence of a black hole at this location, but there was no direct visual evidence until now.
UArizona astrophysicists Feryal Özel and Dimitrios Psaltis identified Sagittarius A* as an ideal target black hole more than 20 years ago. They call it a "Goldilocks black hole," with an environment "just right" for capturing an image.
Parkinson's disease is perhaps best known for its movement-related symptoms, but it can also hinder vocal production. New research suggests that a specific gene commonly associated with Parkinson's may be behind those vocal issues – a finding that could help lead to earlier diagnosis and treatment for Parkinson's patients.
Tree-ring, ice core and volcano experts teamed up to identify one of the most climatically impactful volcanic eruptions in 4,000 years – Aniakchak II. In the process, they narrowed down potential dates for the infamous Thera eruption.
For the seventh year in a row, UArizona hurricane forecasters predict an above-average hurricane season, beginning June 1. Their forecast shows 14 named storms and seven hurricanes developing over the Atlantic Ocean.
The extended UArizona-led mission, dubbed OSIRIS-APEX, will study the near-Earth asteroid Apophis, which is expected to have a close encounter with Earth in 2029.
A team of University of Arizona researchers is working to scale up production of carbon-absorbing marine algae in an effort to curb the worst impacts of climate change.
Coffee is the world's most traded product, and it is highly vulnerable to climate change. Researchers at Biosphere 2 are studying coffee plant sensitivity and how growing and bean processing conditions affect flavor.
UArizona researchers were leaders in a worldwide effort to understand tropical trees and their futures under climate change. They found that heat and drought slow the growth of these trees, which are major carbon dioxide absorbers.
