Extreme supergiant stars known as hypergiants are very rare, with only a few known to exist in the Milky Way. Astronomers have created a detailed, three-dimensional image of one dying hypergiant, providing new insights into what happens at the end of these rare stars' lives.
As heat waves blaze across the U.S., UArizona researcher Ladd Keith says city planners should take the lead in managing and mitigating extreme heat. Keith recently co-authored a report, published by the American Planning Association, that gives planners a set of principles and guidelines to address extreme heat in their communities.
A new study identified a gene variation that could inform clinicians which patients are more susceptible to developing stomach cancer.
The Arizona Queer Archives, the first archive in Arizona to capture the histories and stories of LGBTQI+ communities, has a new home in the University Libraries Special Collections.
UArizona scientists took part in an international planetary defense exercise that used asteroid Apophis – a large, potentially hazardous asteroid – to test the planetary defense response chain.
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.
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.
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.
