NASA’s Nancy Grace Roman Space Telescope is scheduled to launch as a space observatory designed to address multiple major questions in astronomy. According to the sources, the telescope will study how the universe began, what it is made of, and how it has evolved. A key focus is dark energy, the poorly understood component believed to be driving the accelerated expansion of the universe. In parallel, the telescope is expected to search for and discover exoplanets—planets orbiting stars beyond the solar system—using its wide-field observational capabilities. The coverage emphasizes that the mission targets both fundamental cosmology (including the universe’s formation and composition over cosmic time) and the detection of planetary systems elsewhere in the galaxy. Together, the reported scientific goals position the Roman Space Telescope to contribute to efforts to clarify the nature of dark energy while expanding knowledge of exoplanets. The sources describe the telescope as a new platform for observing large-scale and population-level phenomena that are difficult to study with existing instruments.
