NGC 2237 is an emission nebula that forms a portion of the larger Rosette Nebula, situated in the constellation Monoceros approximately 5,000 light-years from Earth. It is classified as a massive H II region, meaning it is an ionized cloud of hydrogen gas actively involved in the formation of new st...
V838 Monocerotis is a red variable star located in the constellation Monoceros. In January 2002, it experienced a major outburst, temporarily becoming one of the largest known stars in the Milky Way. This event produced a striking phenomenon known as a light echo, where the flash of light illuminate...
NGC 2261, commonly known as Hubble's Variable Nebula, is a fan-shaped reflection nebula located in the constellation Monoceros. Its shifting appearance is driven by dense clouds of dust passing close to the illuminating variable star R Monocerotis. It was notably studied by Edwin Hubble in 1916 and...
NGC 2264 is a complex star-forming region in the constellation Monoceros, approximately 2,500 light-years from Earth. The region encompasses several distinct astronomical objects including the Cone Nebula, the Christmas Tree Cluster, and the Snowflake Cluster. NGC 2264 contains numerous young, hot s...
The Angel Nebula, NGC 2170, is a reflection nebula in Monoceros whose dust reflects light from hot young stars in a molecular cloud.
The Cone Nebula resides within the larger NGC 2264 nebula in the Monoceros constellation. It’s a dark emission nebula characterized by a distinct, cone-shaped dust column where intense star formation is occurring. Astronomers study this region to understand the processes of stellar birth and the com...
IC 2177 is a diffuse emission nebula located along the Monoceros-Canis Major border. Discovered in 1898 by Isaac Roberts, it encompasses regions like Sh2-292 and Sh2-296, often referred to as the “Seagull Nebula”. This object is notable for its complex structure and vibrant colors produced by ionize...
The Hubble’s Variable Nebula, formally designated NGC 2261, is a reflection nebula located in the Monoceros constellation. It's notable for its fluctuating brightness observed by Edwin Hubble in 1916, a key piece of evidence supporting his theories about extragalactic distances. Astronomers and rese...
NGC 2346, commonly called the Butterfly Planetary Nebula, is a bipolar planetary nebula located in the constellation Monoceros at an estimated distance of roughly 2,000 to 3,000 light-years. It was discovered by William Herschel in 1785. The nebula is distinguished by its central binary star system...
The Rosette Nebula (NGC 2237) is a massive, roughly circular emission nebula located in the constellation Monoceros, approximately 5,200 light-years from Earth. At its center lies NGC 2244, a young open star cluster whose intense stellar radiation ionizes the surrounding hydrogen gas, causing the ne...
The Seagull Nebula, cataloged as IC 2177, is an extensive region of interstellar gas and dust situated on the border of the constellations Monoceros and Canis Major. Its popular name derives from its visual resemblance to a flying bird, with the wingspan spanning over 200 light-years. The nebula is...
Sharpless 2-292 is IC 2177, the Seagull's Head, an H II region on the Monoceros and Canis Major border discovered by Isaac Roberts.
The Christmas Tree Cluster is an open star cluster located within the NGC 2264 complex in the constellation Monoceros. Situated approximately 2,600 light-years from Earth, the region is an active stellar nursery characterized by a cone-shaped dark nebula and young, hot stars. Discovered by William H...
The Fox Fur Nebula is a region of glowing interstellar gas and dark dust located within the NGC 2264 complex in the constellation Monoceros. It is distinguished by its reddish and bluish appearance, created by a combination of hydrogen gas emissions and starlight reflecting off sooty cosmic dust, wh...
The Monoceros Loop is a massive, faint supernova remnant located in the northern part of the constellation Monoceros. First identified in 1963 through radio astronomy observations, the structure is characterized by its enormous angular diameter of roughly 220 arcminutes. It is an aging remnant of an...
The Cone Nebula is a dark, tapering column of gas and dust within the NGC 2264 star-forming complex in the constellation Monoceros. It appears in silhouette against surrounding ionized hydrogen, while radiation and stellar winds from young, massive stars shape and erode the cloud. Located roughly 2,...
The Red Rectangle Nebula, cataloged as HD 44179, is a distinctive protoplanetary nebula located in the constellation Monoceros. It is known for its striking, mathematically symmetrical rectangular shape and ladder-like rungs of glowing gas. These unique features were formed by periodic outflows of g...
The Seagull Nebula, designated IC 2177, is a large region of nebulosity straddling the border between the constellations Monoceros and Canis Major. It functions as an active star-forming H II region where new stars are being born, illuminated by the surrounding gas. The nebula gets its name from its...
Hubble's Variable Nebula, designated NGC 2261, is a fan-shaped reflection nebula located in the constellation Monoceros. It was first recognized for its changing appearance by astronomer Edwin Hubble in 1916, based on photographic plates taken over time. The nebula's variability is caused by shadows...
IC 447 is a diffuse reflection nebula in the constellation Monoceros, distinguished by its distinct bluish glow caused by massive stars scattering their light off local dust clouds.
IC 2169 is a diffuse reflection nebula in the constellation Monoceros, distinguished by its bluish hue caused by the scattering of nearby starlight off surrounding microscopic dust.
Abell 20 is an ancient planetary nebula in Orion, cataloged by George Abell in 1966, notable for its highly evolved, faint structure.
