| European Southern Observatory (ESO) Announces “Unprecedented Discovery” Of Ripples In “Space Time”
October 19, 2017 by SkyWatch Editor
 Gravitational waves are ripples in spacetime that were first theorized by Albert Einstein about a century ago. Last year marked the first time we’ve been able to observe the phenomena, and so far, all the gravitational waves we’ve observed have been caused by particularly intense events, such as the merging of neutron stars. This type of merger has also been considered the most likely cause of short gamma ray bursts, cosmic explosions that emit massive amounts of light. On August 17, 2017, the Laser Interferometer Gravitational-Wave Observatory (LIGO) caught evidence of gravitational waves passing over Earth — only the fifth time such a detection has been made. Just two seconds later, both NASA’s Fermi Gamma-ray Space Telescope and the ESA’s International Gamma Ray Astrophysics Laboratory detected a short gamma-ray burst in a similar region of the sky. This quick succession led the researchers to believe the gravitational waves and light were caused by a single event. (READ MORE) |
