## What you would see

The frame is filled edge to edge with a dense, deep star field, like a night dusted with bright powder. In the upper center, an irregular dark cavity opens up, rimmed by luminous veils. Its edges glow in lemon yellow, olive green and deep garnet red that seems to emanate from within, like embers behind a cloud. Around it, greenish and golden filaments arch and dissolve into the navy blue of space. Thousands of white and pale blue points speckle the background; a few larger, sharper stars with cross-shaped glints stand out toward the lower right and center. The light is diffuse and ethereal, with no hard shadows, characteristic of a color-mapped infrared photograph. The dust clouds have a cottony, soft texture, contrasted with the crystalline sharpness of the stars. The scale feels immense and dizzying: the nebula dominates the visual foreground, while the background recedes into an infinite tapestry of tiny stars.

## How to look at it

First find the dark hollow near the center and trace its glowing yellow and red rim. Then let your gaze drift into the sea of blue stars in the background and return to the green veils stretching downward, noticing how color reveals dust invisible to the human eye.

## Context

According to source data, this is the reflection nebula IRAS 12116-6001, captured by NASA's Wide-field Infrared Survey Explorer (WISE) and released on October 27, 2010. The source description notes that this cloud of interstellar dust cannot be seen directly in visible light, but WISE detectors observed it at infrared wavelengths, with colors assigned to make the invisible data visible. WISE, launched in 2009, surveyed the entire sky in infrared to study cool objects, galaxies and cosmic dust. Credit is given to NASA/JPL-Caltech/UCLA and the image comes from the NASA Image and Video Library. No additional details about exact distance or illuminating star are provided in the source.

## Curious detail

WISE does not see color like humans do: the greens, reds and blues are translations of infrared light, a way to make the heat of cosmic dust visible.

## Questions

- What changes in your perception when you realize what looks like light is actually heat translated into color?
- How does it feel to see a cloud that exists but your eyes could never see without technology?
- What relationship do you imagine between the empty darkness in the center and the brightness surrounding it?

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

1. Look at the upper center of the image: what dark and irregular shape seems to open up among the bright dust?
2. Count the main colors the record assigns to the bright edges of the nebula: what three warm tones stand out around the hollow?
3. Look at the lower right area and the center: what tiny bright objects, with cross-shaped glints, speckle the entire navy blue background?
