A short description of the Coulomb force.
Monday earlier this week the internet exploded with the news from ESO that two neutron stars merged in the galaxy NGC4993 located 130 million light years away. This was measured on August 17 this year and the discovery was therefore named GW170817, which is short for ‘Gravitational Wave on August 17, 2017’ as measured by LIGO in USA and Virgo in Europe.
Yesterday ESO announced the discovery of gravitational waves and electromagnetic radiation, that originated from a neutron star merger in a galaxy far, far away. Media from all over the world covered the story as it was revealed that some 3,000 scientists had worked for six weeks to decipher the signal, that was received in multiple telescopes and observatories on August 17 this year.
