The Veil Nebula, formally NGC 6960 and NGC 6992, is a vast, filamentary structure within the constellation Cygnus. It represents the aftermath of a supernova event that occurred roughly 8,000 years ago. This ancient nebula’s intricate shapes are formed by expanding gas and dust ejected during the ex...

IC 1340 is a luminous filamentary structure of ionized gas located in the northern constellation Cygnus. It constitutes the southernmost portion of the Veil Nebula, a large, diffuse supernova remnant resulting from a stellar explosion that occurred roughly 8,000 years ago. The glowing gas filaments...

NGC 6979 is a portion of the Veil Nebula, a large supernova remnant located in the constellation Cygnus. The Veil Nebula is the visible portion of the Cygnus Loop, which was created by the explosion of a massive star thousands of years ago. NGC 6979 appears as a filamentary structure of glowing gas,...

Simeis 147 is a vast filamentary nebula located in the Taurus region of the Milky Way. It represents the expanding remains of a supernova explosion that occurred approximately 9,000 years ago. The remnant’s immense size – spanning roughly three degrees – makes it particularly notable for astronomers...

Sh2-240, also known as Simeis 147, is a large supernova remnant located within the Taurus constellation. It’s notable for its intricate filamentary structure and association with the “Spaghetti Nebula” nickname due to its resemblance to strands of pasta. This remnant originates from a star that expl...

The Veil Nebula, formally NGC 6960, is a vast and complex supernova remnant located in Cygnus. It represents the spectacular aftermath of a star’s violent death approximately 10,000 to 20,000 years ago. This filamentary structure spans roughly 110 light-years and provides valuable insight into stell...

Sharpless 2-103 is a section of the Cygnus Loop, a massive supernova remnant nearly 3 degrees across. The broader Cygnus Loop complex contains visible arcs of glowing gas, including the well-known Veil Nebula. This filamentary structure resulted from a massive star explosion roughly 8,000 years ago....

The Tornado Nebula, cataloged as G357.7-0.1, is a complex filamentary emission nebula and supernova remnant located in the Milky Way galaxy near the galactic center in Sagittarius. It is notable for its unusual, swirling funnel-like morphology that closely resembles a terrestrial tornado. The struct...

Designated as Sh2-103 in the Sharpless catalog, this astronomical object is a massive supernova remnant commonly known as the Cygnus Loop. Spanning nearly three degrees in the sky, it consists of a large, filamentary nebula resulting from the explosion of a massive star. The brightest optical arcs o...

Simeis 147, also known as the Spaghetti Nebula or Sharpless 240, is a large, faint supernova remnant located in the constellations of Taurus and Auriga. It has an estimated age of approximately 40,000 years and a projected diameter of around 150 light-years, making it among the largest known superno...

Sh2-91 is a very faint emission nebula located in the northern constellation of Cygnus. It is classified as part of the Sharpless catalog and is specifically identified as the long southern filament of the supernova remnant designated G65.2+5.7. Because of its extremely low surface brightness, it is...

NGC 2736, known as the Pencil Nebula, is a narrow, luminous filament of gas located in the constellation Vela. It is a fragment of the Vela supernova remnant, the expanding debris cloud from a supernova estimated to have occurred roughly 11,000 years ago. The nebula was first catalogued by John Hers...

NGC 2736, widely known as the Pencil Nebula, is a luminous, filamentary cloud of gas located roughly 815 light-years away in the constellation Vela. It represents a small, distinct fragment of the much larger Vela supernova remnant, created when a massive star exploded approximately 11,000 years ago...

RCW 114 is a large, filamentary emission nebula located in the southern constellation of Scorpius. Spanning approximately four degrees across the night sky, the structure is recognized by astronomers as an evolved candidate for a supernova remnant. Its faint, expansive filaments of ionized gas are b...

Pickering's Triangle is a faint, filamentary nebula located in the constellation Cygnus, forming a section of the larger Cygnus Loop supernova remnant. Discovered photographically in 1904 by astronomer Williamina Fleming at the Harvard College Observatory, it was named after the observatory's direct...

The Spaghetti Nebula, cataloged as Simeis 147 or Sharpless 2-240, is a large and extremely faint supernova remnant located on the border between the constellations Taurus and Auriga. It was discovered in 1952 at the Crimean Astrophysical Observatory and spans roughly 3 degrees, or about 6 light-year...

Abell 21, commonly called the Medusa Nebula, is a large, faint planetary nebula in the constellation Gemini. It consists of ionized gas expelled by a dying low-mass star, whose hot remnant illuminates the nebula as a central white dwarf. Its curved filaments suggested the snakes of the mythological...

Sharpless 2-96, or Sh2-96, is a faint emission filament in the constellation Cygnus and an entry in the Sharpless catalog of emission nebulae. It is associated with the large, evolved supernova remnant G65.2+5.7, whose visible structure also includes the filaments catalogued as Sh2-91 and Sh2-94. Th...
