Accessibility Statement

We want deepinthe.space to be usable by curious people with a wide range of abilities, devices, and levels of experience.

Last reviewed

Our target

The site aims to conform to WCAG 2.2 Level AA. We treat accessibility as ongoing work rather than a one-time checkbox, and we prioritise barriers that prevent people from reading, navigating, or contacting us.

What is in place

  • Semantic structure: pages use landmarks, headings, lists, and descriptive link text.
  • Keyboard access: navigation, search, theme control, the cookie banner, and the interactive views can be operated without a mouse.
  • Skip link: keyboard users can jump directly to the main content.
  • Visible focus: interactive elements have a clear focus indicator.
  • Reduced motion: the site respects prefers-reduced-motion and stops decorative animation when requested.
  • Readable contrast: text and controls are designed for comfortable contrast in both dark and light themes.
  • Responsive layout: content reflows on small screens and at increased text size without horizontal scrolling for ordinary text.
  • Accessible names: icon-only controls, search fields, and interactive visualisations have labels.

Known limitations

  • The solar-system view is a rich, animated illustration. Its orbital motion and hover notes may be difficult for some users; the planet pages provide the same information in text form, and reduced-motion mode removes most movement.
  • Some third-party NASA images and archives may not have detailed alternative text beyond the description we provide.
  • External data services (NASA EPIC, NASA Image Library, exoplanet catalogues) can be temporarily unavailable; the site shows a text message when this happens.
  • Automated accessibility checks cannot catch every issue. Manual testing with assistive technology is part of the ongoing plan.

How to report a barrier

If something is difficult to use, please tell us:

  • the page or feature;
  • what you were trying to do;
  • your browser, operating system, and any assistive technology you use;
  • what would make it work better for you.

Use the contact form and include “Accessibility” in the subject. Reports are read and used to prioritise accessibility fixes.

Assessment and compatibility

The site is built with semantic HTML, CSS, and vanilla JavaScript. It is intended to work with current versions of Safari, Chrome, Firefox, and Edge, and with common screen readers such as VoiceOver, NVDA, and JAWS. Testing is performed on desktop and mobile viewports, with keyboard-only navigation and reduced-motion settings.

This statement describes our current target and known state; it is not a certification of full conformance. It will be updated as testing and fixes progress.

Feedback and enforcement

If you are not satisfied with our response, you may contact the relevant accessibility or equality authority in your country. In Switzerland, cantonal equality offices and the Federal Bureau for the Equality of People with Disabilities provide information and signposting.
