左:2026年4月7日 01:05:29(世界時)に撮られた露出1秒のRAW画像1枚(art002e015967)。黒レベル、ホワイトバランス、色変換、一定の明るさ、sRGBガンマだけで現像しています。右:62枚を合成したこの画像。スライダーで境目を動かせます。Left: one 1-second raw frame, art002e015967, taken at 01:05:29 UTC on 7 April 2026, developed plainly (black point, white balance, color matrix, one brightness scale and sRGB gamma). Right: this picture, stacked from 62 frames. Drag to move the divider.
On 7 April 2026, during the Artemis II lunar flyby, the Orion spacecraft passed through the Moon's shadow, and its crew watched a total solar eclipse, with the Sun hidden behind the far side, for almost an hour. They photographed it through Orion's window with a Nikon Z9 and a 35 mm f/2 lens. This picture combines 62 of those raw frames, taken between 00:51 and 01:26 UTC with exposures of up to 13 seconds, into one view that holds both the brightest glow and the faintest stars.
The glow is sunlight scattered by interplanetary dust (the F-corona and zodiacal light). It is brightest close to the hidden Sun and stretches along the ecliptic, the plane of the planets. The thin crescent is the Moon's near side lit by Earthshine, sunlight reflected by Earth; craters along its edge catch the light. The rest of the disk is the unlit far side. Saturn, Neptune, Mars and Mercury line up along the ecliptic at the lower right, and Venus is just outside the left edge. The hidden Sun is 2.8° from the Moon's center, behind the far side.
How it was made
Data: 62 raw frames (Nikon Z9, 35 mm f/2) from NASA's Planetary Data System, Artemis II crew-camera bundle (doi:10.17189/x52v-tb80), NASA IDs art002e015905 to art002e016026
Each frame calibrated (black level, lens vignetting, exposure) and registered star by star (a 3rd-order polynomial per frame); hot pixels fixed
Glow: 55 frames stacked with the stars masked, then a smooth multiscale model; the reflection of Venus in the window removed; the glare around the planets refilled along the ecliptic band
Moon: the 17 sharpest of 26 frames, aligned on the Moon (optical flow), combined, denoised and deconvolved; the glow's bleed across the limb modeled and removed; hot pixels on the dark disk removed
Stars: 9,430 stars, each measured in the frames (position, brightness, blue/red color) and redrawn as a clean round point of that brightness and color. No catalog star is drawn: a star catalog (HYG v4.1) was used to check the positions (709 stars agree to about 2 pixels), to calibrate the colors, and to tell real close pairs from fragments of bright stars
Color: white balance calibrated on 520 catalog stars; the glow then has the color of sunlight, as dust-scattered sunlight should
HDR tone mapping in log space with local contrast; the Moon has its own tone curve
The smaller sizes are rendered at their own size (stars drawn at that size), not resized

Notes
This is a stack and a composite: the glow, the Moon and the stars come from different sets of the same 62 frames.
The stars are redrawn from their own measurements; no catalog star was added.
The far side is shown black: the frames hold no surface detail there, only a smooth haze from the camera and window and a faint reflection.
Nothing was cloned or generated with AI.
The labels on the annotated version are placed with a plate solution on 709 catalog stars.
This is not an official NASA image, and NASA does not endorse it.
