This Christmas, NASA brings an extraordinary gift for astronomers and skywatchers. On December 25, 07:20 am EST, (5.50 pm IST), the space agency’s largest and most powerful space science telescope will launch from French Guiana.

It carries four main scientific instruments and will “hunt for the unobserved formation of the first galaxies, as well as to look inside dust clouds where stars and planetary systems are forming today,” according to NASA.

The liftoff scheduled for December 22 was postponed to December 24 due to difficulties in electronic communications between the launch vehicle and its payload. It was further delayed until Christmas Day due to poor weather conditions at the launch site.

The telescope will help answer our questions about: First light, Assembly of galaxies, Birth of stars and protoplanetary systems and Planetary systems, and the origin of life.
