The world’s largest “ghost particle” detector, located in southern China’s Guangdong province, has shattered expectations in just two months.
Initial results from the vast new Jiangmen Underground Neutrino Observatory (Juno) have shown a record level of precision, surpassing decades of cumulative data from other global experiments on neutrinos.

The immediate success has confirmed that the detector is ready to tackle fundamental questions, potentially uncovering new laws of physics and solving the mystery of matter’s very existence.

From data collected between August 26 and November 2, Juno was able to measure two key neutrino oscillation parameters with a precision 1.6 times greater than the previous 50 years of experiments combined, the Institute of High Energy Physics (IHEP), under the Chinese Academy of Sciences, announced on Wednesday.

“The fact that the Jiangmen neutrino experiment was able to complete such high-precision measurements in just two months demonstrates that the performance of the Juno detector fully meets design expectations,” said Wang Yifang, former director of IHEP, and a spokesman for the Juno collaboration.
