FAQs and answers
What is the James Webb Space Telescope?
The James Webb Space Telescope (JWST) is an orbiting infrared observatory that complements and extends the discoveries of the Hubble Space Telescope.
It has longer wavelength coverage and greatly improved sensitivity, allowing it to look much closer to the beginning of time and to hunt for the unobserved formation of the first galaxies.
How large is the James Webb Space Telescope?
The JWST is as tall as a 3-story building and as long as a tennis court. It is so big that it has to fold origami-style to fit inside the rocket for launch. Once in space, the telescope unfolds, starting with its sunshield.
What are the main goals of the JWST?
The JWST aims to study every phase of cosmic history, from within our solar system to the most distant observable galaxies in the early universe. Its infrared telescope will explore a wide range of science questions to help us understand the origins of the universe and our place in it.
How does the JWST differ from the Hubble Space Telescope?
While the Hubble Space Telescope observes primarily in visible and ultraviolet light, the JWST is designed to observe in infrared light. This allows it to see through dust clouds and observe objects that are too old, distant, or faint for Hubble to detect.
What is the significance of the JWST’s sunshield?
The JWST has a 5-layer sun shield that protects the telescope from the infrared radiation of the Sun, Earth, and Moon. This sun shield provides protection equivalent to SPF 1 million, keeping the telescope’s instruments cool and allowing them to function properly.
What are some recent discoveries made by the JWST?
Recently, the JWST captured a detailed image of an edge-on protoplanetary disc, known as HH 30, around a newly formed star. This observation helps astronomers study how stellar dust behaves during the formation of new stars.
How does the JWST contribute to the search for life beyond our solar system?
The JWST has observed rocky exoplanets in habitable zones—regions where liquid water could exist. Notably, it has studied Earth-sized planets orbiting the red star TRAPPIST-1, located 40 light-years away, analyzing their atmospheres for signs of life.
