It is no exaggeration to say the James Webb Space Telescope (JWST) represents a new era for modern astronomy.
Launched on December 25 last year and fully operational since July, the telescope offers glimpses of the universe that were inaccessible to us before. Like the Hubble Space Telescope, the JWST is in space, so it can take pictures with stunning detail free from the distortions of Earthโs atmosphere.
However, while Hubble is in orbit around Earth at an altitude of 540km, the JWST is 1.5 million kilometres distant, far beyond the Moon. From this position, away from the interference of our planetโs reflected heat, it can collect light from across the universe far into the infrared portion of the electromagnetic spectrum.
