One of the most spectacular achievements in physics so far this century has been the observation of gravitational waves, ripples in space-time that result from masses accelerating in space. So far, ...
Sending a mission to the solar gravitational lens (SGL) is the most effective way of actually directly imaging a potentially ...
new way of looking at the Cosmos. LISA: a kind of physics lab in space. It will test the gravitational reference sensors, the laser interferometry and the micro-Newton thrusters. But instead of a ...
Europe’s gravitational-wave hunters are celebrating. On 1 July, a satellite will wrap up its mission to test technology for the pioneering quest to measure gravitational ripples in the stillness of ...
