What is the James Webb Telescope?
The James Webb Telescope, also known as the JWST for short, is a space telescope that is orbiting around the Sun about one million miles away from us and it conducts infrared astronomy. The JWST is a joint project from NASA whose main goal is to find the first galaxies in the early universe and to view stars forming planetary systems. The JWST is the largest optical telescope in space so far and its impressive high resolution and sensitivity allow us to see objects about 13.8 billion light years away (which is basically seeing the universe 13.8 billion years back in time). Many people call this telescope a time machine because of how far it can look back in time! What also makes it special is that its mirrors are made up of beryllium and are coated with gold which can see the universe in light that is invisible to human eyes. It also cost up to 10 billion dollars making it an impressive but risky project!
How do Aerospace Engineers Contribute?
Aerospace engineers played a vital role in the development of the James Webb Space Telescope (JWST), contributing to various aspects of the project. They were involved in the conceptual design, defining mission requirements and evaluating technical solutions. These engineers designed and built the complex optics and instruments, including the segmented primary mirror, and developed innovative thermal control systems to manage extreme temperature variations. Aerospace engineers ensured a robust and lightweight structure, capable of withstanding launch and space conditions, and designed and tested intricate deployment mechanisms. They oversaw integration, conducted extensive testing, and collaborated with space agencies for successful launch and mission operations. Throughout the mission, aerospace engineers continue to provide support and maintenance to ensure JWST’s operational excellence, making it a remarkable feat of engineering that expands our understanding of the universe.
List of Some of The Many Discoveries JWST Has Made
- Found water vapor in a planet forming zone; this means that other planets could potentially hold water simmilar to earth!
- Found a black hole that existed 570 million years after the Big Bang
- Helped scientists see that stars are being formed in the Eagle Nebula
- Found multiple planets that were orbiting stars. These planets could potentially be habitable
