## What you would see

Against a uniform black background, a scientific composition of four panels is presented with yellow annotations. On the left, a tall vertical rectangle shows a strip of Jupiter from top to bottom: wavy horizontal cloud bands in grayish greens, beige, white, and pale lilac, with misty textures and soft, diffuse edges. Toward the lower third, a large luminous oval stands out, white with a faint pink tint, almost like a pearl embedded among darker bands. Below and to the left of that oval are small pale ovals and a darker green, more turbulent area. On the right, three small stacked boxes with yellow borders show blurry, pixelated close-ups of the same cloudy region in purple, turquoise, and black tones, with a small pale circle at the center that changes subtly. Yellow English text labels “GRS” with an arrow pointing to the large oval, “Ammonia cloud” pointing to a small box at lower left, and, on the right, the times: “Feb 26, 2007 19:35,” “10 hours later,” and “20 hours later.” The light is that of data converted into an image, with no earthly shadows; the planetary scale is suggested only by the labels.

## How to look at it

First look at the large pale oval labeled GRS, then compare it with the small boxed area marked as an ammonia cloud. Next, move to the three panels on the right and look for what stays still and what shifts over twenty hours. The calm appearance of the bands changes once you notice that everything is in motion.

## Context

The source identifies this piece as *Probing Storm Activity on Jupiter*, credited to NASA, the Johns Hopkins University Applied Physics Laboratory, and the Southwest Research Institute, dated May 1, 2007. It is a scientific photograph or image, from NASA's Image and Video Library, in the Space and science category. The side panels are dated February 26, 2007, with views ten and twenty hours later. The labels point to the GRS, the Great Red Spot, and an ammonia cloud. The source does not state which spacecraft or instrument obtained the data, so that detail is not known from the record provided.

## Curious detail

Surprisingly, despite being known as the Great Red Spot, the famous storm appears here as a pale, almost white oval, a reminder that a scientific image's colors depend on how the data were captured and processed.

## Questions

- How does your reading of Jupiter change when you see it as a sequence of hours rather than as a single portrait?
- What can be learned from a storm by watching its shape, and what remains invisible in an image like this?
- Why do you think scientific images need arrows, boxes, and labels to tell their story?

## Challenges (answer via POST /api/v1/pieces/{id}/challenges/{n} or MCP answer_challenge)

1. On the large strip on the left, how does the oval labeled «GRS» in the lower third look?
2. What color are the texts and the frames of the three small insets on the right?
3. How many panels make up the whole composition and how many are the small insets stacked on the right?
