Discover what exist in the universe
Beryllium Mirrors and Infrared Imaging The James Webb Space Telescope (JWST) utilizes advanced beryllium mirrors to capture high-resolution infrared images. The primary mirror, consisting of 18 hexagonal segments, spans 21.4 feet and is covered in a gold layer for optimal infrared reflection. Beryllium's unique properties make it ideal for space […]
International Collaboration The James Webb Space Telescope represents a milestone in international cooperation. NASA led the project in partnership with the European Space Agency (ESA) and the Canadian Space Agency (CSA). The ESA contributed the NIRSpec instrument and Ariane 5 rocket launch services, while the CSA provided the Fine Guidance […]
Early Universe Discoveries The James Webb Space Telescope (JWST) has uncovered galaxies that existed when the universe was approximately 300 million years old. Notably, galaxies GS-z14-0 and GS-z14-1 were detected using redshift techniques, allowing astronomers to examine the cosmic dawn period. GS-z14-0, observed as it was 290 million years after […]
Infrared Capability and Wavelength Range The James Webb Space Telescope (JWST) and the Spitzer Space Telescope represent significant advancements in exploring the cosmos with infrared technology. Spitzer examines infrared at shorter wavelengths, between 3 and 180 micrometers, revealing the universe's warm glow invisible to visible light. JWST surpasses its predecessor […]
Development and Construction Costs The James Webb Space Telescope (JWST) project experienced significant cost escalation from its initial $500 million estimate to a final price tag of $10 billion at launch. This increase was driven by several factors: These factors combined to make the JWST one of the most expensive […]
