This vibrant structure provides valuable insight into processes of star birth and death observed b...
M1-67 is an emission nebula surrounding the Wolf-Rayet star WR 124 in the constellation Sagitta, roughly 20,000 light-years from Earth. The nebula consists of gas expelled by the massive, evolved star and shaped by its powerful stellar wind. Its irregular knots and clumps are moving outward, providi...
The Thor’s Helmet Nebula, formally designated NGC 2359, is an emission nebula situated in the constellation Canis Major. It's notable for its distinctive shape resembling a helmet, created by the powerful stellar wind emanating from the Wolf-Rayet star WR 7. This type of nebula is commonly associate...
NGC 2359 is an emission nebula located in the constellation Canis Major. It’s notable for its distinctive helmet-like shape, sculpted by the powerful stellar winds emanating from the Wolf-Rayet star WR 7. This nebula provides astronomers with a visual example of how intense radiation can influence i...
Sh2-308 is an emission nebula located within the Canis Major constellation. It’s characterized by a prominent bubble structure formed around the Wolf-Rayet star EZ Canis Majoris. This bubble, spanning approximately 60 light-years, represents material ejected from the star's intense stellar winds. As...
NGC 6888, commonly called the Crescent Nebula, is an emission nebula in the constellation Cygnus. It formed as fast stellar wind from the Wolf-Rayet star WR 136 collided with material expelled during an earlier phase of the star's evolution, producing an expanding shell of energized gas. Its curved...
The Dolphin-Head Nebula, also designated Sh2-308, is an emission nebula within the larger Canis Major wolf-rayet nebula complex. This distinctive bubble shape arises from powerful stellar winds emanating from the WR star EZ Canis Majoris. Astronomers and amateur observers studying star formation, pa...
The Dragon's Egg Nebula is a bipolar emission nebula surrounding a massive star in the constellation Norma, originally discovered by James Dunlop in 1826.
WR 140 is a variable star system located in the constellation Cygnus, consisting of a massive Wolf-Rayet star and a hot O-type giant companion. These two stars follow a highly eccentric 7.9-year orbit, coming close enough together to generate colliding stellar winds that shock the surrounding gas. T...
Gamma Velorum is a prominent multiple-star system located in the southern constellation of Vela, approximately 1,100 light-years from Earth. The primary component of the system is a spectroscopic binary consisting of a blue O-type giant and the closest and brightest Wolf-Rayet star known to Earth. T...
The Thor’s Helmet Nebula, formally NGC 2359, is an emission nebula located in the constellation Canis Major. It's notable for its distinctive bubble-like shape created by the intense stellar winds of a Wolf-Rayet star, WR 7. This structure provides valuable insight into how stars interact with and s...
WR 104 is a Wolf-Rayet star located roughly 7,800 light-years away in the constellation Sagittarius. It forms a spectroscopic binary with an OB companion, and the system is surrounded by a rotating pinwheel-shaped dust nebula imaged at infrared wavelengths. The orbital geometry has led researchers t...
Thor's Helmet, catalogued as NGC 2359, is an emission nebula in the constellation Canis Major, roughly 15,000 light-years from Earth. It consists of an expanding bubble and filamentary arcs shaped by radiation and powerful stellar winds from the Wolf-Rayet star WR 7. Its helmet-like form and promine...
WR 102 is a rare oxygen-sequence Wolf-Rayet star, classified WO2, in the constellation Sagittarius. Its spectrum is dominated by highly ionized oxygen, carbon, and helium produced in an extremely hot, dense stellar wind, and model estimates place its surface temperature above 200,000 kelvins. It is...
Thor's Helmet, NGC 2359, is a Wolf-Rayet emission nebula in Canis Major, shaped by winds from the massive star WR 7.
NGC 2359, commonly known as Thor's Helmet, is an emission nebula located in the constellation Canis Major. It is situated roughly 15,000 light-years from Earth and is characterized by a central bubble structure with wing-like appendages. The nebula's distinctive shape is sculpted by powerful stellar...
The Peony Star, formally designated as WR 102ka, is a massive Wolf-Rayet star situated in close proximity to the center of the Milky Way galaxy. It is distinguished by its extreme luminosity, estimated to be approximately 3.2 million times that of the Sun, placing it among the most luminous stars cu...
The Crescent Nebula, designated NGC 6888, is an emission nebula located approximately 5,000 light-years away in the constellation Cygnus.
