## What you would see

The work presents as a striking scientific triptych, three vertical panels side by side showing the same patch of sky. The backdrop in all three is a deep velvety black densely sprinkled with hundreds of pinpricks of light — distant stars and galaxies in white, soft yellow, pale blue and orange. At the centre of each panel sits UGC 1382. In the left panel it looks like a compact oval smudge of pearly white light, with a bright core and a very faint diffuse halo, isolated in dark emptiness. In the middle panel that halo is transformed: delicate filamentary spiral arms in icy blue emerge and curl around the nucleus, while the surrounding star field appears richer and more colorful. In the right panel a huge translucent cloud in emerald green envelops the galaxy, stretching far beyond the optical disk with a hazy, uneven texture and wispy edges. This veil represents gas invisible to the human eye. The sense of scale is immense, the light is faint yet crisp, and the contrast between darkness, stellar sparkle and washes of color creates a powerful feeling of gradual discovery.

## How to look at it

Read the triptych from left to right to experience the reveal. Notice how something that looks small and ordinary becomes structured and then vast. Pay special attention to the green cloud — invisible gas that completely redefines the galaxy's size.

## Context

According to source data from NASA/JPL/Caltech dated 2016-07-11, the composite compares views of galaxy UGC 1382 from different telescopes. The left view from the Sloan Digital Sky Survey in optical light shows a plain elliptical. The middle adds ultraviolet from the Galaxy Evolution Explorer and deep optical from Stripe 82 of SDSS, revealing spiral arms. The right adds low-density hydrogen gas in green detected at radio wavelengths by the Very Large Array, showing its true enormous extent. Because it is assembled from such different parts it was nicknamed the Frankenstein galaxy, and it is considered one of the largest isolated galaxies known.

## Curious detail

GALEX could capture the faint blue spiral arms only from space, because Earth's atmosphere blocks ultraviolet light.

## Questions

- How does this piece challenge the idea that seeing is believing when we use only one kind of light?
- Why do you think scientists chose the nickname Frankenstein for this galaxy?
- How does the green gas cloud in the third panel affect your sense of scale and isolation in the universe?

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

1. In the right panel, what color is the huge hydrogen cloud surrounding the galaxy that reveals its giant size?
2. How many vertical panels make up the triptych showing the same patch of sky in different light?
3. In this artwork, what background object appears as hundreds of white, yellow, blue and orange dots on black velvet?
