New photo from James Webb Telescope

Living Accessibility: NASA’s new photos contain Stellar ALT text

Highlighting the power of ALT text is the National Aeronautics and Space Administration (NASA). This major institution models what ALT text can and should look like in their recent Tweet showing the newest photos of their new high quality telescope.

Learn more about the impact this has for people with visual impairments and hear from the team responsible for creating the ALT  text in this article by the Washington Post: The unexpected star of NASA’s Webb images — the alt text descriptions

ALT text included here for the above photo (all credit to NASA and their team for the following text)

The image is divided horizontally by an undulating line between a cloudscape forming a nebula along the bottom portion and a comparatively clear upper portion. Speckled across both portions is a starfield, showing innumerable stars of many sizes. The smallest of these are small, distant, and faint points of light. The largest of these appear larger, closer, brighter, and more fully resolved with 8-point diffraction spikes. The upper portion of the image is blueish, and has wispy translucent cloud-like streaks rising from the nebula below. The orangish cloudy formation in the bottom half varies in density and ranges from translucent to opaque. The stars vary in color, the majority of which, have a blue or orange hue. The cloud-like structure of the nebula contains ridges, peaks, and valleys – an appearance very similar to a mountain range. Three long diffraction spikes from the top right edge of the image suggest the presence of a large star just out of view.
