## What you would see

This infrared image presents a deep-space view dominated by soft, billowing clouds of interstellar dust and gas. Occupying the lower center and spreading outward, a large nebular formation glows in translucent turquoise and emerald green on its left side, transitioning to warm pinkish-red on the lower right. At the heart of that reddish glow sits a brilliant, almost white stellar point surrounded by a diffuse rosy halo. The surrounding sky is a deep, velvety black densely speckled with countless tiny stars rendered in electric blue and white pinpricks of varying brightness and sharpness. In the upper left quadrant, a small but distinct double-toned dot in lime green and yellow stands out against the darker background; this is the moving asteroid. The overall texture is hazy and grainy, characteristic of infrared imaging, with layered veils of dust creating a sense of depth and vast scale. Light appears diffused throughout the nebula rather than from a single direction, emphasizing the ethereal luminosity of the gas clouds against the stark darkness of space.

## How to look at it

First take in the broad turquoise and pink nebular cloud and the field of blue stars. Then look to the upper left for the small green-yellow dot; that tiny moving speck is the main subject. Notice how its color and isolation set it apart from the fixed stars and the diffuse glow of the nebula.

## Context

According to source data, this image was captured on August 21, 2013 by NASA's NEOWISE mission and released by the Jet Propulsion Laboratory (JPL-Caltech). It shows the near-Earth object 1998 KN3 as it appears to zip past a dense cloud of gas and dust near the Orion Nebula, a prominent star-forming region in our galaxy. Infrared imaging allows astronomers to peer through dust and highlight the nebula's structure and thermal emission. The asteroid is visible as a small greenish point due to its motion during the exposure. No further details about its size or orbit are provided in the original description.

## Curious detail

NEOWISE, which captured this view, was the repurposed WISE space telescope, originally launched in 2009 to survey the entire sky in infrared light before being dedicated to finding and tracking near-Earth asteroids.

## Questions

- How does knowing the small green dot is a moving asteroid change how you read the vast background?
- What does seeing the universe in infrared rather than visible light reveal or hide?
- What emotions arise from contrasting a tiny nearby object with a massive distant stellar nursery?

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

1. What colors does the small double dot that is the asteroid at the upper left appear in?
2. On what date was this image captured by the NEOWISE mission according to the record?
3. What bright object wrapped in a pinkish halo stands out at the lower right end of the nebula?
