UArizona astronomers have joined an international effort to study the aftermath of the brightest flash of gamma rays ever observed. Observations involving UArizona telescopes and instruments provide astronomers with a "cosmic lab" to study how massive stars die.

Bhattacharya's research focuses on the molecular pathways involved in the degeneration of axons, the threadlike cell structures that are critical for neuronal communication.

As a sizable asteroid makes a close pass by Earth, a team of UArizona students is ready to observe the action to practice and test procedures that could be useful in mitigating an impending asteroid impact in the future.

NASA's OSIRIS-REx spacecraft is cruising back to Earth with the sample it collected from asteroid Bennu's rocky surface in 2020. When the sample capsule parachutes down into the Utah desert on Sept. 24, the UArizona-led OSIRIS-REx mission will become the first U.S. mission to return an asteroid sample to Earth.

Using the James Webb Space Telescope, astronomers observed detailed features, including roiling clouds of dust, in the atmosphere of a brown dwarf planet 40 light-years away.

With this new stamp, the U.S. Postal Service celebrates NASA’s seven-year OSIRIS-REx mission to study and map the asteroid Bennu and deliver a sample of the surface to Earth in September 2023. The sample will help scientists learn how the solar system formed.

Imagine a home computer operating 1 million times faster than the most expensive hardware on the market. Now, imagine that being the industry standard. UArizona physicists hope to pave the way for that reality.

Mapping a large coastal glacier in Alaska revealed that its bulk sits below sea level and is undercut by channels, making it vulnerable to accelerated melting in an already deteriorating coastal habitat.

Dozens of presentations from UArizona experts, a film festival and more are on tap at this year's Wonder House as the university returns to South by Southwest.

CatSat is a small satellite carrying a new communications concept – an inflatable antenna – into space. Led by UArizona students and supported by engineers from local aerospace companies, the project offers students a rare chance to get hands-on experience with spaceflight technology.
