Dark energy, exoplanets and black holes: What Nasa’s new Roman telescope will explore
NASA launched the Nancy Grace Roman Space Telescope to explore dark energy, black holes, and search for exoplanets. The telescope aims to uncover about 100,000 new exoplanets and has a field of view at least 100 times larger than Hubble's. It will take three months to reach its orbit around the second Sun-Earth Lagrange point, or L2.
