Imagine a telescope that can see back in time to the first galaxies’ birth. It can spot light from objects over 13 billion years old. The James Webb Space Telescope (JWST) has changed how we explore space, revealing the universe’s deepest secrets.
Launched on 25 December 2021, JWST is a huge step forward in astronomy. It has a 6.5-metre mirror and special infrared tech. This lets it see objects 100 times fainter than the Hubble Space Telescope.
Webb’s abilities mark a new era in space exploration. It’s about 1.5 million kilometres from Earth, at the second Lagrange point. It works at just 40 Kelvin, showing us details of distant galaxies and stars we couldn’t see before.
The telescope’s mission will change how we see the cosmos. It’s expected to work for 10 years, maybe longer. Webb will gather about 100 terabytes of data each year. This will give scientists a deep look into the universe’s start and its most mysterious areas.
