NASA Unveils ‘Roman Space Telescope’ to Probe Mysteries of Dark Matter
In April 2026, the United States of America (USA) space agency National Aeronautics and Space Administration (NASA) unveiled the ‘Nancy Grace Roman Space Telescope’, a powerful wide-field observatory designed to survey vast regions of the universe and detect planets beyond the solar system.
About Roman Space Telescope:
Purpose: It will also study dark matter and dark energy, unseen forces that make up about 95% of the universe.
Legacy: The telescope is named after Nancy Grace Roman, NASA’s first Chief Astronomer, often called the ‘mother of the Hubble Space Telescope’ for her pioneering role in advancing space-based astronomy.
Cost: The telescope was built at a cost of USD 4 billion (Bn) in more than a decade and will be positioned 1.5 million (mn) kilometres (kms) from earth to probe vast regions of space.
Data Flow: The telescope will transmit around 11 terabytes (TB) of data to earth each day.
