NASA now is targeting Oct. 312021, for the launch of the agency’s James Webb Space Telescope from French Guiana.
Webb is designed to discover and study the first stars and galaxies that formed in the early Universe. To see these faint objects, it must be able to detect things that are ten billion times as faint as the faintest stars visible without a telescope. This is 10 to 100 times fainter than Hubble can see.
The successor to Hubble is almost ready for launch. It’s really coming this year, too!
