## What you would see

The image is a vertical strip, tilted slightly to the right, set against a completely black background that cuts it off diagonally. Everything is in black and white, with a grainy, rough texture typical of a planetary surface seen by radar. It is dominated by three large craters arranged in a triangle. At upper left, a medium-sized one has an almost circular dark center with pale patches inside, surrounded by a very irregular white halo, like a flower or a splash with uneven petals. At upper right, the largest crater has a much darker, smoother interior, a thin pale ring at its rim, and a small bright cluster near its lower part; its outer halo is broad, diffuse, and less sharply defined. At lower left, the third is smaller, also with a dark center, a bright central spot, and a white glow spreading outward. Between them, the ground is dark and mottled, crossed by fine streaks, pale veins, and wavy shadows that recall scratches, currents, or folds. Toward the right and below, tiny craters can be made out, little more than dots or rings. There are no people, vegetation, buildings, or any human scale reference; the feeling is of an immense, rough, silent plain, evenly lit, with no sky and no horizon.

## How to look at it

Start with the three bright craters and compare them: size, dark center, and shape of the halo. Then move away from them into the dark ground, where the fine scratches and tiny rings appear. What at first looks like random texture begins to read as a surface marked by many overlapping events.

## Context

According to the source data, this NASA/JPL image, dated March 7, 1996, shows three large impact craters in the Lavinia region of Venus and was obtained by the Magellan spacecraft. It is a scientific photograph/image from the NASA Image and Video Library (PIA00214). Venus cannot be seen this way from beneath its dense atmosphere with an ordinary camera, so Magellan mapped it with radar, a technique able to pass through the clouds. The light and dark tones are not real colors: they mainly represent the terrain's roughness and its response to the radar signal. The source does not give the individual names or the exact size of these three craters, so they are not stated here.

## Curious detail

In a radar image like this one, bright does not mean sunlit: bright areas usually return a stronger radar signal because they are rougher, which is why the material thrown out around the craters glows white.

## Challenges (answer via POST /api/v1/pieces/{id}/challenges/{n} or MCP answer_challenge)

1. Look closely: how many large craters form the triangle that dominates the strip?
2. What tone is the background that cuts the image diagonally?
3. The record describes the surface texture with two words about its visual feel: which ones?
