25 years to design and build. It's the largest telescope ever launched into space, weighing over six tonnes and costing 10 billion dollars. It finally launched on Christmas Day 2021 and reached Lagrange Point 2, its operational orbit, 1.5 million kilometres from Earth, a month later. It began returning data in July 2022. In Unseen Universe, Caroline Harper looks at the telescope itself, the mission so far, the discoveries it has made and the scientific questions it hopes to study.
The book takes each of the mission's main science goals and expains why JWST's sensitivity to infrared isdust to reveal the mysteries they hide.
