Sensor used at CERN could help gravitational wave hunters

It started with a relatively simple goal: create a prototype for a new kind of device to monitor the motion of underground structures at CERN. But the project—the result of a collaboration between CERN and the Joint Institute for Nuclear Research (JINR) in Dubna, Russia—quickly evolved. The prototype turned into several full-blown devices that can potentially serve as early warning systems…

Arecibo gets $19M grant to find and study NEOs

NEOs are near-Earth objects, asteroids and small comets that sweep near Earth and have the potential to cause harm. Arecibo Observatory in Puerto Rico has, since the 1990s, been finding about 60 to 120 of these objects every year. Source: https://earthsky.org/human-world/arecibo-observatory-19-million-grant-neos…
