The first galaxies in the Universe were born enshrouded in a “foggy” gas, and could not be seen clearly until they had cleared up this fog. Using the James Webb Space Telescope, a team of researchers led by astronomers at the Cosmic Dawn Center in Copenhagen has now detected the hitherto most distant — and hence earliest — sign of this important epoch in the history of the Universe. A galaxy, seen only 330 million years after the Big Bang, has formed a bubble of transparent gas around itself, revealing that the epoch began earlier than thought. The result has been published in the prestigious journal Nature.
Researchers from California State University Northridge (CSUN), National University of Singapore (NUS), NASA Jet Propulsion Laboratory (JPL), and University of Wisconsin-Madison (UW-Madison) have introduced a new concept called autonomous additive manufacturing (AAM), where AI agents take over tasks traditionally managed by human operators. This breakthrough represents a major step toward creating autonomous manufacturing systems, offering improvements in knowledge representation and multi-modal capabilities in additive manufacturing (AM) processes.
The lead Ph.D. candidate, Mr. Haolin Fan, explained: "In the era of generative AI, this research points out a future where human expertise and AI collaborate seamlessly, leading to more resilient and adaptable manufacturing systems that could transform industrial production."
