NGC 7094 and the Rarely Imaged “Shenron Nebula” [O III]

At the center of this richly detailed wide-field view lies NGC 7094, a faint planetary nebula in the constellation Pegasus, showcasing its delicate blue-green glow from doubly ionized oxygen ([O III]). Surrounding it is an intricate tapestry of dusty interstellar cirrus, laced with faint red hydrogen emission. Cutting dramatically across the frame, the shimmering cyan ribbon known as the “Shenron Nebula” [O III] Arc reveals a rarely imaged ionization front, its ethereal form resembling a mythical dragon winding through the cosmic clouds. This combination of a planetary nebula and expansive, unrelated foreground structures creates a striking juxtaposition of astrophysical phenomena within the same celestial canvas.

The Iris Nebula in a Field of Cosmic Dust

Nestled 1,300 light-years away in the constellation Cepheus, NGC 7023, also known as the Iris Nebula, is a striking example of a reflection nebula. Illuminated by a hot, young star at its center, the surrounding interstellar dust scatters the starlight, producing the soft blue glow seen in this image. The intricate network of dark tendrils, shaped by magnetic fields and turbulent motion, testifies to the dynamic nature of the interstellar medium.

Captured in June 2025 by the Game Shark Collective, John Poole, Jeff Newgard, Derek Morf, and Stefan Pommerin—this deep image reveals not just the core of the Iris but also the vast, faint molecular dust clouds that envelop it. With exceptional detail and contrast, the nebula appears to bloom from within a cocoon of cosmic smoke, highlighting the complex interplay between light and matter in star-forming regions.
