## What you would see

At the center dominates a huge star in vivid, incandescent orange, its surface mottled and turbulent like boiling lava, surrounded by a soft glowing halo that bleeds into the darkness of space. On the left edge, a small dark sphere rimmed by a thin bright outline — the exoplanet — appears to graze the stellar disk mid-transit. Around the star, reddish filamentary loops and ribbons of plasma rise and curl in irregular, translucent arches, resembling solar prominences. The background is a deep starfield, black speckled with tiny white points of light. In the upper right, a faint bluish-gray nebula with dark veining drifts. A pale, diffuse horizontal band, beige to tan, stretches behind the star, suggesting a dusty disk or orbital plane. The lighting is warm and dramatic, with stark contrast between stellar brilliance and the blackness of the void, conveying cosmic scale and raw energy. Small dark spots and grainy mottling across the stellar face hint at intense magnetic activity typical of a very young star.

## How to look at it

Start with the contrast of the dark planetary silhouette against the blazing orange stellar disk and see how the light rims the planet. Then trace the looping plasma prominences at the edges and the faint dusty band behind the star — those details turn a simple transit into a story of a newborn, volatile system.

## Context

This is an artist concept released on June 20, 2016 by NASA/JPL-Caltech, based on data from NASA's Kepler Space Telescope. It depicts K2-33b, described at the time as one of the youngest exoplanets yet detected, with an estimated age of only a few million years. According to the source data, it completes an orbit around its host star in about five days. Its Neptune-like size combined with its tight orbit and youth raises questions for planet formation theories, whether it migrated inward quickly from farther out or formed in place. As an illustration, it is not a direct photograph.

## Curious detail

K2-33b is slightly larger than Neptune yet orbits its star in just five days, while Mercury, the closest planet to the Sun, takes 88 days, showing how unusually tight and extreme this young system is.

## Questions

- How does the scale difference between the tiny dark planet and the giant star make you feel?
- How does knowing this is an artist concept based on data, not a real photo, change how you read it?
- What visual clues suggest youth and turbulence in this star?

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

1. I am round, small and dark and I am just touching the edge of the big orange star on the left. What am I?
2. We are reddish glowing arcs coming out of the star like fiery streamers. What are we?
3. I was published on June 20 2016 and I am not a photo but a drawing born from Kepler telescope data. What kind of image am I?
