University of Arizona astronomers have peered back to a time when the universe was just less than 300 million years old. The research team, using JWST revealed something extraordinary in the galaxy: significant amounts of oxygen.

SAN ANTONIO — March 10, 2025 — Using data collected by NASA’s Juno spacecraft as it flew past Jupiter’s highly volcanic moon Io in late 2023 and again in early 2024, a Southwest Research Institute-led team identified electrons with energies enhanced by processes in the region connecting the moon to Jupiter’s ionosphere, called an Alfvén wing. A paper published in Geophysical Research Letters emphasizes how these electrons, and their variation within that region, shape the plasma environment around Io.

Hypervelocity impacts from space debris pose significant risks to spacecraft and satellites in outer space. To address this challenge, Prof. SU Zhongqing, Head of the Department of Mechanical Engineering and Chair Professor of Intelligent Structures and Systems at the Hong Kong Polytechnic University (PolyU), as well as a key member of the Research Centre for Deep Space Explorations, along with his research team, has developed an innovative sensing technology to efficiently evaluate the health of space systems under hypervelocity impact of space junks. In recognition of this translational research and development (R&D) work, he has been awarded the Innovation and Technology Fund (ITF) (Special Call for Aerospace Technology) by the Innovation and Technology Commission (ITC).
