James Webb Space Telescopeis ready for launch

• Explore the early phases of cosmic history

• Discover planets outside the solar system

WASHINGTON Monitoring Desk – The James Webb Space Telescopeis finally set for launch in late December after decades of waiting. This elescopeis is the most powerful space observatory ever built,

 The telescope will be placed in orbit about a million miles from Earth, roughly four times the distance of our planet from the Moon, says media reports.

Webb has two primary scientific missions, which together will account for more than 50 percent of its observation time.

First, explore the early phases of cosmic history, looking back in time to only a few hundred million years after the Big Bang.

Astrologers want to see how the very first stars and galaxies formed, and how they evolve over time.

Its second major goal is the discovery of exoplanets, meaning planets outside the solar system. It will also investigate the potential for life on those worlds by studying their atmospheres.
