The JWST is the most powerful space telescope ever developed by NASA. Along with the Canadian Space Agency and the European Space Agency.

What is JWST?

James Webb will orbit the sun, around the second Lagrange point (L2), 1 million miles (1.5 million kilometers) from the blue planet. Primary mirror size: 6.5 meters (21.3 feet) across.


Webb’s primary mirror spans 6.5 meters (21 feet, 4) across and is made up of 18 hexagonal mirror segments measuring 1.32m (4.3 feet) in diameter.


WST weigh approximately 14,000 pounds, it’s about as much as a full-size school bus. From Earth, the JWST will appear more than 10,000 times fainter than the faintest star.
