She is wearing a white spacesuit used for spacewalks, and it matches the surrounding space station hardware in appearance. Earth's horizon is visible in the background of the scene.

ALT A nebula made of clouds of gas and dust with stars forming within. In the center and out to the left it is filled with thin, wispy blue gas that forms delicate layers. Around this are thicker orange clouds with dark ridges. Thin red filaments of gas cross the center of the nebula. Glowing bubbles in the gas contain dense, very bright clusters of stars. In the edges, distant stars are visible as bright points on a dark background. Credit: ESA/Webb, NASA & CSA, E. Sabbi, M. Zamani (ESA/Webb)

ALT A composite image of a radio wave formation that looks a lot like a treble clef musical symbol, hovering in the midst of two colliding galaxy clusters. There are many specks of light set against the blackness of space; those are galaxies and stars. At the center of the image is a large, oval, blue-purple cloud with ragged edges. In the middle of the purple field, tilting slightly to our left, is what appears to be a giant treble clef, loosely drawn with a neon pink marker. Like the musical notation for which it's named, the formation has a strong vertical stroke with a continuous, fluid line swooping back and forth as it moves from top to bottom.
