James Webb Space Telescope

Launched in December 2021, James Webb Space Telescope reveals the earliest galaxies with infrared eyes, spotting a galaxy at redshift 13.2, just 320 million years after the Big Bang. Its 6.5-meter mirror provides 6 times the collecting area of Hubble, enabling atmospheric signatures of exoplanets like TRAPPIST-1e. Webb's operational temperature is 40 K, colder than the average space telescope, ensuring stable data for over 5,000 hours thus far. This mission is 20% more efficient in infrared detection than any predecessor.
