Not a new thing.
Herschel space observatory operated in same location (L2-point) as JWST and it was IR telescope.

Mirror sizes:
Hubble 4.0 m2 (43 sq ft)
Herschel 9.6 m2 (103 sq ft)
JWST 25.4 m2 (273 sq ft)
Hubble had ~40% of the Herschel's collecting area and Herchel had 40% of the JWST's collecting area.
- supernova87a 4y agoThat is a good point -- my simplification of the advance provided by JWST is aimed at saying, JWST is kind of the first major telescope with such depth and resolution to complement the deep fields of HST that everyone is so familiar with. Herschel, while impressive also, was far-IR (if I recall) and much lower resolution, which was good for certain research areas, but less complementary to the HST deep fields for the, well, currently fashionable, recent study of galaxies at high redshift.
