Understanding the James Webb Space Telescope
The JWST is a space-based infrared observatory designed to succeed Hubble, with capabilities optimized for infrared astronomy. Unlike visible-light telescopes, JWST can see through cosmic dust clouds, revealing previously hidden regions of star formation and planetary systems. Its primary features include:
Large Segmented Mirror: The telescope features a 6.5-meter primary mirror, significantly larger than Hubble’s 2.4-meter mirror, enabling greater light collection and higher resolution.
Infrared Observing Instruments: JWST’s suite of instruments allows it to detect faint infrared signals, essential for studying distant galaxies and exoplanets.
Sunshield Technology: A five-layer sunshield protects the telescope from solar radiation, maintaining extremely low operational temperatures necessary for infrared detection.
Orbital Position: JWST orbits near the second Lagrange point (L2), approximately 1.5 million kilometers from Earth, providing a stable, cold, and unobstructed view of space.
Advanced Spectroscopy: Its instruments can analyze the chemical composition of exoplanet atmospheres, detect water and organic molecules, and study the formation of planetary systems.
JWST aims to address key questions in cosmology and astrophysics, including the formation of the first galaxies, star birth, planet habitability, and the potential for life beyond Earth.
