The James Webb Space Telescope (JWST) launched on December 25th, 2021 and is in the process of traveling its gravitationally stable destination, Lagrangian point L2. L2 is one million miles distant from Earth and the telescope will have to make some course corrections to get there.

JWST is stated to be much more powerful than the Hubble Telescope and can see in 'infrared', enabling it to pick out planets around stars, efficiently. Even more, it can analyze planet atmospheres for signs that life may be active on a discovered planet. JWST is claimed to be powerful enough to see further back in time, regarding the initial creation of the Universe, to within the first million years after the 'Big Bang'.

So, what happens to Hubble? Hubble will continue to be used until it fails and is thereafter, no longer serviceable.

Lagrangian Points is something that often escapes people. These are gravitational stable points which occur between two larger mass gravitational bodies and will hold much smaller mass bodies in a stable gravitational equilibrium and position.

The Sun-Earth system has 5 Lagrangian points L1 through L5 which are explained in this wiki.
