Lately, I’ve read a news about gravitational waves. Last August, two neutron stars entered in collision which created a huge explosion that resulted in many gravitational waves and radioactive material.  The first waves ever detected were in 2015, but with the last events, scientists have been able to detect for the first time light from a gravitational wave source.  They also could observe the effects of that encounter between two neutron packed stars. At the moment it was detected, astronomers from all around the world focused their equipment on this extraordinary phenomenon.
