TECHNICAL DEFINITION

An exoplanet, or extrasolar planet, is a celestial body orbiting a star other than the Sun, detected through methods like transit photometry or radial velocity, offering insights into planetary formation and potential extraterrestrial life.

BACKGROUND

The James Webb Space Telescope (JWST) is a space telescope designed to conduct infrared astronomy. It is the largest telescope in space, and is equipped with high-resolution and high-sensitivity instruments, allowing it to view objects too old, distant, or faint for the Hubble Space Telescope. This enables investigations across many fields of astronomy and cosmology, such as observation of the first stars and the formation of the first galaxies, and detailed atmospheric characterization of potentially habitable exoplanets.
