The Webb telescope is composed of some very large structures, and those have to fit together before, during, and after launch. Extreme care has to be taken when moving equipment that weighs thousands of pounds. This episode of Behind the Webb gives us a glimpse into what it takes to test the compatibility between the backplane that will hold the primary mirror segments, the sunshield, and the spacecraft bus. We also see how the sunshield will be pulled into position, giving us a sense of how large the observatory will be when it's in orbit.

$Webb Telescope Data, Translated to Sound — Cosmic Cliffs: Mountains Experience the first full-color images and data from NASA’s James Webb Space Telescope in a brand new way. A near-infrared image of the Cosmic Cliffs in the Carina Nebula, captured by NASA’s Webb Telescope, has been mapped to a symphony of sounds to create a data sonification. This video only includes sounds from the bottom half of the image, which resembles a mountain range in ruddy shades of orange and red. This half of the image has a meandering melodic line to follow the shape of that “mountain range” as it rises and falls in the image, through the center of the frame, from left to right. The jagged line between denser and thinner areas of gas and dust is the arc of the sonification’s melody. Dimmer, dust-obscured areas that appear lower in the image are represented by lower frequencies and clearer, undistorted notes. All stars are represented by a combination of pitches and processed piano notes, but the brightest stars with longer diffraction spikes also carry crashes and clangs from cymbals. Sonifications support blind and low-vision listeners first, but are designed to be captivating to anyone who tunes in. This sonification, which scans the image from left to right, was adapted to a video to allow sighted viewers to watch as a vertical line moves across the frame. Brighter light in the image is louder. The vertical position of light also dictates the frequency of sound. For example, bright light near the top of the image sounds loud and high, but bright light near the bottom is loud and lower pitched. This sonification does not represent sounds recorded in space. Two musicians mapped the telescope’s data to sound, carefully composing music to accurately represent details the team would like listeners to focus on. In a way, this sonification is like modern dance or an impressionist painting – it converts Webb’s image to a new medium to engage and inspire listeners.
