Goa PIO leads Nasa team to find farthest group of galaxies

An international team of astronomers linked to Nasa, led by an Indian-origin Goa-born scientist, Vithal Tilvi, has discovered a never-before-seen group of galaxies, now labelled EGS77, which is the farthest group of galaxies to have ever been sighted. In 2013, Tilvi was also part of a team that discovered the farthest single galaxy ever sighted by astronomers.
