The Engraved Hourglass Nebula (also known as MyCn 18) is a young planetary nebula situated in the southern constellation Musca about 8,000 light-years away from Earth. It was discovered by Annie Jump Cannon and Margaret W. Mayall during their work on an extended Henry Draper Catalogue. At the time [January 18, 1996] it was designated simply as a small faint planetary nebula. Much improved telescopes and imaging techniques allowed the hourglass shape of the nebula to be discovered by Raghvendra Sahai and John Trauger of the Jet Propulsion Laboratory on January 18, 1996. It is conjectured that MyCn 18's hourglass shape is produced by the expansion of a fast stellar wind within a slowly expanding cloud which is denser near its equator than its poles.

The soft appearance of the clouds, the complex relief of the nebula makes me want to reach out and touch it, and its texture is further highlighted by the red and blue starlets. The lighting in this piece is perfect, and it helps position the planet and its moon in the space of the piece, making the illusion of depth complete. The planets themselves are flawless in the way their texture, atmospheric shine and torn rockiness speak of the rough environment... even little details such as the variety of sizes and colors of the stars in the background were taken into account, making this picture, all in all, a masterpiece.
