Telescope Overview

The James Webb Space Telescope has arrived at its final destination, about 1 million miles (1.5 million kilometers) from Earth; the telescope will orbit around Lagrange point 2 (L2) on the far side of Earth from the Sun. In this orbit, Webb can maintain a safe distance from the bright light of the Sun, Earth, and Moon, while also maintaining its position relative to Earth.

Telescope Measurements for Life-Size Comparison Activities

  • How big is the mirror? 
    Webb’s segmented primary mirror has a diameter of 6.6 meters (21.7 feet). Each of the 18 segments is 1.32 meters (4.3 feet) across. The area of the mirror is approximately 25 square meters (270 square feet) and the mass is 705 kilograms (1,550 pounds on Earth).
  • How big is the telescope? 
    The sunshield dimensions are 21.2 by 14.2 meters (69.5 by 46.5 feet) and the height of the entire observatory is 8 meters (28 feet).

3D Printed Bubble Wands

Kauai Community Science Center in Hawaii made use of a 3D printer to create hundreds of James Webb Space Telescope (JWST) themed bubble wands and JWST models. In addition, they partnered with The Hawaiʻi State Public Library System for a reading challenge and a JWST model brown bag activity for visitors to take home. Check out the 3D printed bubble wands here: and the take-home brown bag activity here:

NASA Webb Space Telescope Augmented Reality App child with iPad looking at floating model

Augmented Reality (AR) App

NASA has developed an augmented reality to be used with an iPhone or iPad to place a floating virtual model of Webb in your surroundings, take photos, and learn all about this incredible mission. In augmented reality, you can place a full sized, virtual model of the Webb telescope outside or you can adjust the size and virtually place it on your desk or kitchen table.

Hosting a Community Event

The James Webb Space Telescope (Webb) is the largest, most powerful and complex space telescope ever built and launched into space. NASA and its partners want to share the experience of the Webb Space Telescope’s first images with communities all over the United States and abroad. NASA and its partners invite community organizations to celebrate the first images from the James Webb Space Telescope. Webb, the most audacious scientific endeavor to understand the nature of the universe, has reached its orbit point a million miles from Earth and in July 2022 when it sends its first images back to Earth.The goal of this NASA initiative is to create and nurture generations of science enthusiasts, including underserved audiences, through long-term, meaningful engagement with Webb’s discoveries.

  • Map of official NASA Community Event for First Images 2022 locations
    The map and list of selected NASA Webb Space Telescope community events is now available.

  • You can still host an event if you aren't an "official" NASA Webb community event! 
    There are still many resources available for hosting events.
