WASHINGTON: Nasa laun­ched its new flagship space telescope on Sunday, embarking on a multi-year mission to create an unprecedented map of the cosmos and shed light on some of the biggest mysteries in physics.

Designed to take a panoramic view of the vast reaches of space, the Roman Space Telescope “will help unlock the secrets of the universe”, US President Donald Trump said on Friday during a ceremony at Nasa headquarters in Houston, Texas.

Standing over 12 metres (39 feet) tall, the state-of-the-art observatory launched from the Kennedy Space Centre in Florida aboard a SpaceX Falcon Heavy rocket.
