Indian space lab observes galaxy cluster 800mn light years away
India's first dedicated multi-wavelength space observatory AstroSat has captured an image of a merging galaxy cluster, named Abell 2256 which is more than 800 million light-years away from Earth. The image has captured three separate clusters of galaxies merging into a single massive cluster. The merging cluster has over 500 galaxies and is 1,500 times more massive than our galaxy.
