Pocket
Planetarium

An early iOS prototype of Cosmos, built for a phone rather than a projector. Drift outward from the Sun to Neptune — thirty astronomical units of scrolling — or let the show carry you. The moons and the JunoCam gallery continue below the journey.

Which is where this one belongs. Open it full screen rather than in a frame.

Tonight's show

The Sun, eight planets, twenty-two moons and thirty photographs of Jupiter, developed by strangers.

This is a prototype, not a release. It is a design study for a phone app — every figure is read from the same static tables the decks use, and nothing is wired to a live source. Above 560px it draws its own device frame rather than the one on this page. The three production decks are unaffected by anything here.

What's in the build
01

Journey

Opens full-bleed on the Sun, then scrolls outward through all nine bodies to Neptune. Each opens a plate carrying the same figures as the Solar System deck. "Begin tonight's show" runs it hands-free instead, eight seconds a chapter.

02

Moons

All twenty-two, filterable by system, each disc captioned with radius and orbital period. A true-scale toggle sizes them against each other, and a pinch card sets the seven largest beside Mercury.

03

Gallery

Thirty JunoCam frames developed by volunteers, filterable by region and by treatment. A draggable before/after seam makes the argument for processing in a single picture.

04

Colophon

Provenance for the figures and imagery, typographic credits, and links out to Sol and the Mission Juno processing gallery.
