## What you would see

A schematic illustration shown from a great distance, not a photograph. In the lower right, a small yellow, glowing Sun is surrounded by thin white elliptical orbits, like rings seen at an angle. From there, a pale diagonal line stretches toward the upper left and connects to a dark blue curved band labeled "Termination Shock" in white English text. Further out, a mottled violet band speckled with countless tiny white dots is labeled "Heliosheath"; it suggests a dense region filled with particles. Outside it, on the far left, the background turns orange, sandy and grainy, dotted with faint spots. At the upper left edge sits the spacecraft: a large white parabolic dish seen in profile, dark mechanical bodies, small structures and a very long, thin antenna extending toward the left. A thick white arrow comes in from the upper left, crosses the orange zone and points toward the inner band. Deep indigo blue dominates the right side, with smooth, almost empty surfaces, in contrast to the textured, speckled outer edges. The composition makes the Sun look minuscule and the spacecraft isolated at the frontier.

## How to look at it

Start with the tiny Sun in the lower right and follow the diagonal line outward until you reach the spacecraft; that journey conveys the scale. Then look at the labels for the layers and notice the white arrow entering from outside, which points to the real subject: particles that do not come from the Sun.

## Context

This artist's concept comes from NASA/JPL-Caltech, dated December 16, 2011, and was published through the NASA Image and Video Library. According to the source description, it shows the Voyager 1 spacecraft in a new region at the edge of the Solar System, where more high-energy particles were entering from outside. The labels name the termination shock and the heliosheath, outer zones of the bubble shaped by the solar wind. It is not a real photograph, but a schematic illustration, not to scale, made to explain measurements taken far from Earth. Details on how the measurements were visualized are not provided.

## Curious detail

Voyager 1 was launched in 1977 and is one of the most distant human-made objects; this 2011 image still placed it at the edge, before crossing into interstellar space.

## Questions

- What does it feel like to depend on a diagram to imagine a place no camera can photograph as a whole?
- How does the image change when you notice the spacecraft is tiny compared with the bubble surrounding the Sun?
- What differences do you imagine between the environment inside the heliosheath and the space beyond it?

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

1. Looking at the lower right corner, what color is the tiny Sun surrounded by white orbits?
2. How many curved bands with English labels cross the image?
3. In the upper left, what white shape stands out on the lonely probe?
