The James Webb Space Telescope (JWST) is the most powerful space telescope ever created. It was in development for a quarter century before its successful launch on December 25, 2021. Designed for infrared astronomy, it will be able to peer back to the very beginnings of the universe, to the first stars and galaxies.
At the center of the JWST is its iconic primary mirror. Made from 18 hexagonal gold-plated beryllium mirror segments, this 6.5 meter mirror provides more than six times the light-gathering area of the Hubble Space Telescope's mirror.
In order to allow the JWST to block incoming heat from the Earth, Moon, and Sun at the same time while also remaining at a constant distance from Earth, it operates in a halo orbit at the L2 Lagrange point. What that means is that the JWST will circle around a particular point in space approximately 1,500,000 km (930,000 mi) beyond Earth's orbit around the Sun.
A Lagrange point is a place in space where the interacting gravity of two massive objects is able to keep a very small object in equilibrium. Lagrange points are great spots for satellites because it doesn't take many course corrections to keep the satellites in place with relationship to Earth.
Our James Webb Space Telescope Necklace is really two designs in one: it shows the world-renowned mirror on one side and an engraving of the Lagrange points on the other.
Here's how to interpret the engraving and find the location of the JWST:
The pendant is made from polished golden steel and comes on a sturdy 18 inch gold-plated chain. It measures 1 inch (~25.5mm) in diameter and is very durable. It will be a reminder of new horizons and space exploration for years to come.
