NASA has successfully completed the full assembly of the Nancy Grace Roman Space Telescope, marking a major milestone for the next-generation infrared observatory. With its powerful wide-field camera and advanced coronagraph, Roman is expected to transform our understanding of dark energy, galaxy formation, and exoplanets once it launches later this decade.NASA has successfully completed the full assembly of the Nancy Grace Roman Space Telescope, marking a major milestone for the next-generation infrared observatory.
