Gas filaments appear to splash outward from the nebula center, colored yellow, magenta, and blue. A faint black border with right angles at the corners of the images show where the telescope\u2019s field of view stops. Small white stars dot the background.

A large, detailed view of the Moon fills the upper portion of the image. Below the astronauts, text reads: “10 Days | 685,000 Miles Around the Moon for All Humanity.” At the bottom, the title “Artemis II” is displayed in large letters, along with the names and roles listed: “Reid Wiseman — Commander, Victor Glover — Pilot, Christina Koch — Mission Specialist I, Jeremy Hansen — Mission Specialist II.” The NASA and Artemis logos appear at the top of the poster.
