## What you would see

Against a deep black field scattered with hundreds of tiny stars in white and pale blue, six appearances of the same comet form a descending diagonal from upper left to lower right. Each shows a bright, almost white nucleus surrounded by a reddish-orange glow and a diffuse, silvery-gray tail trailing behind like a brushstroke of luminous dust. Beside each nucleus, simple white text marks a time stamp: 10:26 PM at the top, then 7:17 PM, 4:07 PM, 2:33 PM, 11:23 AM and 8:14 AM at the bottom, tracking its motion on May 20, 2014. In the upper right corner, lettering reads «Comet PanSTARRS 2012 K1 May 20th, 2014 (all times EST)». Toward the lower left third, a larger, soft-edged bluish oval stands out from the pinprick stars: a distant background galaxy. The overall light is dim and characteristic of an infrared image, with contrast between the blackness of space, the warm red of cometary dust, and the cool sparkle of background stars. Small field stars and faint artifacts fill the frame, creating a composition that feels both scientific and choreographic, like luminous footprints in the dark.

## How to look at it

Follow the comet's diagonal trail from top to bottom and notice how each tail points the same way, like wakes behind a traveler. Then pause on the soft blue galaxy on the left and contrast its diffuse, still light with the sharp, reddish glow of the moving comet.

## Context

The image comes from NASA's NEOWISE mission and was captured on May 20, 2014, according to source data. It shows comet C/2012 K1, also known as comet Pan-STARRS, in a time-lapse composite of infrared frames documenting its apparent movement across the sky over a single day. Such composites make the trajectory and activity visible; the infrared brightness traces dust warmed by sunlight. The bluish patch near the lower left is an unrelated background galaxy that happened to lie in the field of view. NEOWISE repurposed the WISE space telescope to detect and characterize near-Earth objects and small solar system bodies.

## Curious detail

NEOWISE sees in infrared light, so the reddish glow around the comet is not its color to the naked eye but the heat of dust shed as it nears the Sun, invisible without special instruments.

## Questions

- How does it feel to see the same object repeated at different hours against the same starfield?
- How does your perception shift knowing the bluish smudge is an entire galaxy, billions of stars far more distant than the comet?
- What connection do you see between human time measured in hours and the cosmic time of a comet's journey?

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

1. How many times does comet Pan-STARRS appear in the composite image and in which general direction does it move?
2. What bluish oval object appears in the lower left third and is neither a star nor part of the comet?
3. What colors distinguish the halo around the comet nucleus from the black background of space?
