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, ...

Neutron stars are ultra-dense remnants of massive stars that collapsed after supernova explosions and are made up mostly of subatomic particles with no electric charge (i.e., neutrons). When two ...

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 ...

Sending a mission to the solar gravitational lens (SGL) is the most effective way of actually directly imaging a potentially habitable planet, as well as its atmosphere, and even possibly some of its ...
