The gravitational wave whose presence was postulated by Albert Einstein 100 years ago has again been detected for the second time. The first detection of gravitational waves was made in September and announced on February 11. It created a scientific sensation and was a benchmark in physics and astronomy, transforming a quirky implication of Einstein's 1916 theory of gravity into the realm of observational astronomy. This time the gravitational waves were observed by twin observatories in the United States late on December 25, 2015.  The confirmation of the presence of gravitational waves would definitely be a phenomenal source of new information about our galaxy.
