This image is a composite of images made with the NASA/ESA Hubble Space Telescope and the Atacama Large Millimeter/submillimeter Array (ALMA), both observing the binary star system LL Pegasi. The old star LL Pegasi is continuously losing gaseous material as it evolves into a planetary nebula, and the distinct spiral shape is the imprint made by the stars orbiting in this gas. The Hubble image can be seen here, the ALMA image here. Links: Celestial Spiral with a Twist 3D view of LL Pegasi
