NGC 7048 is a planetary nebula situated approximately 6,000 light-years away in the constellation Cygnus. Glowing with an apparent magnitude of around 12.1 and spanning roughly 60 to 62 arcseconds in diameter, it exhibits a distinct asymmetrical shell created by gas expanding outward from a central white dwarf remnant. Its complex physical structure features a prominent, bright hydrogen outer envelope wrapped around delicate, highly ionized oxygen filaments, standing apart from typical circular ring nebulae and making it a captivating object for deep-sky astronomical observation.
