The Veil Nebula is a vast emission nebula located in Cygnus. It represents the expanding remains of a star explosion, specifically the supernova associated with the Cygnus Loop. This remnant, formed approximately 10,000 to 20,000 years ago, exhibits intricate filament structures and intense radiatio...
The Eastern Veil Nebula, catalogued as NGC 6992 and NGC 6995, is a bright filamentary arc of ionized gas forming the eastern section of the Cygnus Loop, a supernova remnant in the constellation Cygnus. The gas was heated by a supernova explosion estimated to have occurred roughly 8,000 years ago. It...
The Spaghetti Nebula, formally Simeis 147, is a delicate supernova remnant located within the constellations Taurus and Auriga. It’s notable for its intricate, thread-like structure resembling strands of spaghetti—a visual consequence of expanding gas and magnetic fields. This filamentary nebula, pa...
The Pencil Nebula, or NGC 2736, is a prominent filament within the Vela supernova remnant. This structure formed from the expanding debris of a star that exploded approximately 10,000 years ago. Its distinctive shape – resembling a pencil lead – makes it notable for astronomers studying shock waves...
The Dark Doodad Nebula is Sandqvist 149, a dark nebula located in the southern sky. It’s notable for its dense dust and gas composition, resembling a filament structure as observed in infrared light. Astronomers and researchers studying dark nebulae, particularly those related to star formation regi...
The Seahorse Nebula, catalogued as Barnard 150, is a dark nebula in the constellation Cepheus. It appears as a long, sinuous silhouette because its cold interstellar dust blocks visible light from the dense background of Milky Way stars. The cloud contains several denser condensations associated wit...
The Musca Dark Cloud is a nearby dark molecular filament in Musca, measured in 2016 as a roughly 6-parsec velocity-coherent sonic structure.
The Double Helix Nebula is an elongated cloud of cosmic dust and gas situated approximately 300 light-years from the supermassive black hole at the center of the Milky Way. Its distinct, twisting DNA-like structure was discovered using infrared observations from the Spitzer Space Telescope. Astronom...
