New NASA telescope to probe dark energy, dark matter and exoplanets

NASA is set to launch its new flagship space observatory, the Nancy Grace Roman Space Telescope, in a mission to probe some of the universe's biggest mysteries. The $4 billion project, which is nine months ahead of schedule, will be launched aboard a SpaceX Falcon Heavy rocket from NASA's Kennedy Space Center in Florida. The telescope is a follow-on to the Hubble Space Telescope and the James Webb Space Telescope, and its capabilities will expand on the knowledge gained by those pioneering observatories.

The Roman Space Telescope's primary mission is to study the cosmos, including dark energy, dark matter, and exoplanets. Its vast reach will allow scientists to find the weird, the rare, and the unusual in the universe. The telescope's panoramic view of space and rapid survey speeds will enable scientists to study the structure, composition, and evolution of the cosmos as never before.

The telescope's main survey will take over a year and involve over two billion galaxies, providing insights into how structures in the universe have grown and evolved over time.

One of the key goals of the mission is to unlock the fundamental nature of dark matter and dark energy, which make up most of the universe's contents. While ordinary matter is thought to make up about 5% of the universe, dark matter and dark energy may represent 27% and 68% respectively. The telescope's measurements of how galaxies cluster and how matter bends light through gravitational lensing will help test whether Einstein's theory of general relativity remains valid on the largest scales.
