Advanced quantum detectors designed at Texas A&M University are reinventing the search for dark matter, an unseen force that science has yet to explain.

Our galaxy’s supermassive black hole is famous for being one of the dimmest in the universe. Evidence from a new space telescope shows that might not always have been the case. Sagittarius A*, located at the center of the Milky Way Galaxy, appears to have flared dramatically sometime within the past few hundred to 1,000 years, according to X-ray emissions observed by the XRISM space telescope. These surprising findings unveil new details of how supermassive black holes evolve. They also teach astronomers lessons about the history of our cosmic home.

Organised by the Beijing-Hong Kong Academic Exchange Centre, the results of the annual selection for the ‘Top 10 Innovation & Technology News in Hong Kong 2025’, have recently been announced. The University of Hong Kong (HKU) is pleased to report that three of its groundbreaking research projects have made it onto this prestigious list, leading among all local institutions. These selected projects in the fields of medical health and astronomical sciences highlight HKU's strong capabilities in advanced translational research and technology transfer. The university aims to address global challenges and deliver impactful real-world solutions, all while striving to benefit society and support sustainable development.  

Astronomers have found something the universe wasn’t supposed to have: a galaxy cluster blazing with hot gas just 1.4 billion years after the Big Bang, far earlier and hotter than theory predicts. The result, published today in Nature, could upend current models of galaxy cluster formation, which predict such temperatures occur only in more mature, stable galaxy clusters later in the universe’s life.
