Credit: CC0 Public Domain Ten years after scientists first detected gravitational waves emerging from two colliding black holes, the LIGO-Virgo-KAGRA collaboration, a research team that includes Columbia astronomy professor Maximiliano Isi, has recorded a signal from a nearly identical black hole collision. Improvements in the detection technology allowed the researchers to see the black holes […]

The JUNO Sphere. Credit: JUNO Collaboration Neutrinos are one of the most enigmatic particles in the standard model. The main reason is that they’re so hard to detect. Despite the fact that 400 trillion of them created in the sun are passing through a person’s body every second, they rarely interact with normal matter, making

The Shanghai Outer Ring Tunnel runs across the Huangpu River, with areas covered by mucky soil and silty clay (top). The researchers placed a portable muon detector within the tunnel to monitor muon flux as a way to measure the sediment buildup (bottom). Credit: Khaw et al.
