The opening sequences guide viewers through the Milky Way, diving into colourful emission nebulae and dense star forming clouds where young stars are still embedded in gas and dust. These passages showcase how Webbs near and mid infrared instruments penetrate obscuring material to reveal newly formed stars and the intricate filaments and knots that trace their surrounding environments. Well known stellar nurseries such as the Carina Nebula "cosmic cliffs," the Pillars of Creation in the Eagle Nebula and the Orion Nebula serve as archetypes for these nebular fly throughs, illustrating the kinds of regions featured in the tour.

From there, the virtual camera leaves the Galaxy and moves into fields crowded with distant galaxies, including interacting systems where tidal forces distort spiral arms and generate long streams of stars and gas. Compact groups like Stephans Quintet provide classic examples of these scenes, where Webb resolves shock fronts, dust lanes and active galactic nuclei that stand out in the infrared. The motion of the camera, combined with Webbs high spatial resolution, maintains sharp detail even as the view pushes from wide fields down into small scale structures within each galaxy.

Later segments focus on massive galaxy clusters that act as gravitational lenses, bending and magnifying light from even more distant background galaxies. In these regions, elongated arcs and multiple images trace the distribution of mass in clusters similar to SMACS 0723 and related systems that Webb has observed in depth. Some of these fields capture light that has travelled for more than 10 billion years, illustrating how Webb connects visually spectacular scenes with measurements of galaxy evolution in the early Universe.

Throughout the 43 minute sequence, the camera path is designed to guide the viewer smoothly from one target to the next, using pans, rotations and deep zooms to create a sense of three dimensional depth from two dimensional images. The production draws on the work of specialist visualisation teams, who process Webb's calibrated infrared data, map different wavelengths to visible colours and construct longform animations that preserve scientific integrity while maximising clarity for non specialists.

The video also serves as a visual recap of Webbs first four years in space. Launched on an Ariane 5 rocket from Europes Spaceport in French Guiana on 25 December 2021 and beginning science operations in mid 2022, Webb has built an image library spanning nearby star forming regions, planetary nebulae, interacting galaxies and deep extragalactic fields. These datasets provide the raw material for the anniversary fly through, which functions both as an outreach piece and as a reminder of the mission's breadth, from the solar neighbourhood out to some of the most distant galaxies currently observable.

Fly through Webbs cosmic vistas is available via ESAs multimedia portal, where the full resolution version can be streamed or downloaded, and through the agencys official YouTube channel embedded on the same page. Viewers can pause to inspect individual frames, revisit favourite regions and use the material for educational or outreach purposes under ESA's multimedia usage guidelines. Even without an official, frame by frame target list, the production stands as an "eye candy" special built from Webbs greatest hits, offering a sustained visual immersion in the telescope's most striking views.
