The James Webb Space Telescope (JWST) is set to launch in 2023, and it’s set to be one of the most advanced telescopes ever made. This revolutionary telescope will be able to observe far-off galaxies, stars, and planets in unprecedented detail, and will allow us to gain a better understanding of the universe. The telescope is an impressive 21-feet long and will be orbiting at a distance of 1 million miles from Earth. With its 18-segmented primary mirror and four science instruments, the telescope will be able to detect light with a wavelength range that is 100 times greater than that of the Hubble Space Telescope. This means that the James Webb Space Telescope will be able to see parts of the universe that were previously hidden from us.
