## What you would see

A wide, horizontal view of deep space is filled edge to edge with stars and translucent clouds, with no empty margins. Running diagonally from the lower left toward the upper right are two large nebulous structures. Each contains one or two dark, hollow-looking cavities in deep red and burgundy, rimmed by foamy, irregular borders of pale green, emerald, and teal. The cloud edges look fibrous and torn, like smoke or sea foam lit from within. On the right, the cavity is larger and is crowned by an intensely bright white and peach-colored knot, with smaller orange glows around it; on the left, two adjoining reddish hollows are separated by a narrow bridge of brighter cloud. Thousands of tiny stars speckle the entire field, mostly icy blue and white pinpoints, with a few warmer orange and red dots, including a noticeable orange star near the top center. The black background is not uniformly black: it shifts toward deep blue and green where thin veils of gas drift across it. Near the bottom center, slightly right of middle, sits a tiny elongated bluish-white smudge. Overall scale feels immense and depth uncertain, as dust, cavities, and stars overlap in layers.

## How to look at it

Start with the two reddish cavities and notice that neither is a solid object: both are hollowed-out spaces edged with green clouds. Then move to the bright knot in the upper right and let the tiny blue stars come forward. Finally, compare the edges — some are sharp, others dissolve into the background like smoke.

## Context

According to the source, this image, credited to NASA/JPL-Caltech/UCLA and dated May 24, 2010, was produced with NASA's Wide-field Infrared Survey Explorer (WISE) and published by the NASA Image and Video Library. It is a large mosaic of two clouds of gas and dust known as the Heart and Soul nebulae. It is a scientific image in infrared light, so its greens, reds, and blues are assigned colors used to render information the human eye cannot see directly, not the appearance they would have in visible light. These regions are known as places where new stars form within cold dust.

## Curious detail

In infrared images like this one, telescopes can reveal stars and warm dust hidden inside dark clouds that would block much of the visible light.

## Questions

- How does knowing that these are assigned infrared colors change what you trust or feel when looking at the image?
- Do the nicknames Heart and Soul help you see shapes in the clouds, or do they limit what else you might notice?
- What might be happening inside the darkest cavities, where almost no stars seem to shine?

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

1. If you look from corner to corner, how many large cloud-shaped nebulae form the main diagonal of the image?
2. In the largest cavity on the right, what color is the brightest knot crowning it at the top?
3. What tones dominate the foamy edges around the reddish hollows?
