Abstract: One hundred and thirty million years ago and one hundred and thirty million light years away from us, a collision of two neutron stars happened resulting in the production of a gigantic fire ball whose brightness was more than a billion times that of our sun, expelling gravitational waves and a gamma ray burst. The gravitational waves were detected by both LIGO and VIRGO and the Gamma Ray burst by the gamma ray detector on the Fermi Satellite on the 17th of August 2017 and the announcement of the event was made one month laterafter 70 ground based  and satellite based telescopes confirmed  their observations in several bands of the electromagnetic spectrum. It is estimated that in this particular event gold equivalent to the mass of the earth was produced and also a huge quantity of heavy elements like platinum, uranium, etc. The first technical paper contained the names of 3500 authors.

Prof. Sreekantan will give an account of this unique celestial event and discuss its consequence to the future of physics, astrophysics and international collaborations in scientific research.

All are welcome
