James Webb Space Telescope

The James Webb Space Telescope (JWST) is humanity's most powerful observatory, seeing the universe in infrared light. Think of it as "super-eyes" that see much further and clearer than the older Hubble. Its 6.5-meter mirror, made of 18 hexagons, resembles a honeycomb. To stay cool, it’s protected by a sunshield as big as a tennis court. JWST doesn't orbit Earth like the Moon; it sits 1.5 million kilometers away at the L2 point. There, in Earth's perfect shadow, it observes the birth of the first stars and galaxies, acting as a time machine to the deep past.

Transit timing variations occur when a planet crosses in front of its host star at slightly different times than expected. These small shifts provide information about the orbital path of a planet and the presence of other gravitational forces in the system. By measuring these variations, observers can understand the dynamics and evolution of distant planetary systems. The James Webb Space Telescope provides the high-precision data necessary to track these subtle events across a wide range of...
