Scientists claim to create most detailed map of dark matter 
A research group led by an Indian-origin Professor Priyamvada Natarajan has produced one of the highest-resolution maps of 'dark matter', an unseen mass believed to comprise 80% of the matter in the universe. The detailed map could provide understanding for the unseen mass responsible for gravitational lensing, a phenomenon that bends light reaching us from distant galaxies, said the researchers.
