Its name means “unicorn” in Latin. Monoceros was introduced by the Dutch astronomer and cartographer Petrus Plancius from the observations of Dutch navigators in the 17th century. The constellation represents the mythical single-horned, horse-like creature.</p> <p>Monoceros is a relatively faint constellation, containing only a few fourth magnitude stars, but it is nevertheless home to several notable stars: the famous variables S Monocerotis, R Monocerotis, and <a href="https://www.constellation-guide.com/v838-monocerotis/">V838 Monocerotis</a>, Plaskett’s Star, which is one of the most massive binary stars known, and the triple star Beta Monocerotis.</p> <p>Monoceros also contains several interesting deep sky objects: the open cluster <a href="https://www.messier-objects.com/messier-50-heart-shaped-cluster/">Messier 50</a> (NGC 2323), the <a href="https://www.constellation-guide.com/rosette-nebula/">Rosette Nebula</a>, the <a href="https://www.constellation-guide.com/christmas-tree-cluster/">Christmas Tree Cluster</a>, the <a href="https://www.constellation-guide.com/cone-nebula/">Cone Nebula</a>, and <a href="https://www.constellation-guide.com/hubbles-variable-nebula-ngc-2261/">Hubble’s Variable Nebula</a>, among others.</p> <h2 style="text-align: center;">Facts, location and map</h2> <p>Monoceros is the 35th constellation in size, occupying an area of 482 square degrees.

The constellation was created to fill the area between two large constellations, <a href="https://www.constellation-guide.com/constellation-list/orion-constellation/">Orion</a> and <a href="https://www.constellation-guide.com/constellation-list/hydra-constellation/">Hydra</a>, where there weren’t any constellations introduced in Greek times.</p> <p>Plancius introduced the unicorn figure because the mythical animal appears several times in the Old Testament of the Bible. The constellation is not associated with any particular myth. The German astronomer Jakob Bartsch included the constellation in his 1624 star chart as Unicornus.</p> <h2 style="text-align: center;">Monoceros stars</h2> <h3 style="text-align: center;">α Monocerotis (Alpha Monocerotis)</h3> <p>Alpha Monocerotis is the brightest star in Monoceros.

The star has an apparent magnitude of 15.74 and is approximately 20,000 light years distant from Earth.</p> <p>The star was discovered when it experienced an outburst and suddenly brightened for a few weeks in 2002, and was thought to be one of the <a href="https://www.star-facts.com/largest-stars/">largest stars discovered</a>. The cause of the event is still uncertain, but it resulted in a light echo, with the surrounding dust being illuminated by the star’s light. The star grew enormously in size, but did not expel its outer layers, which is what would normally happen in a nova event.</p> <p>The star has also increased in temperature and luminosity, but decreased in radius. It is now 15,000 times more luminous than the Sun and has a radius 380 times solar.</p> <div id="attachment_16859" style="width: 510px" class="wp-caption aligncenter"><img decoding="async" aria-describedby="caption-attachment-16859" class="lazy lazy-hidden wp-image-16859" src="//www.constellation-guide.com/wp-content/plugins/a3-lazy-load/assets/images/lazy_placeholder.gif" data-lazy-type="image" data-src="https://www.constellation-guide.com/wp-content/uploads/2021/08/V838-Monocerotis.webp" alt="light echo,v838 monocerotis star" width="500" height="546" srcset="" data-srcset="https://www.constellation-guide.com/wp-content/uploads/2021/08/V838-Monocerotis.webp 502w, https://www.constellation-guide.com/wp-content/uploads/2021/08/V838-Monocerotis-275x300.webp 275w" sizes="(max-width: 500px) 100vw, 500px" /> <noscript><img decoding="async" aria-describedby="caption-attachment-16859" class="wp-image-16859" src="https://www.constellation-guide.com/wp-content/uploads/2021/08/V838-Monocerotis.webp" alt="light echo,v838 monocerotis star" width="500" height="546" srcset="https://www.constellation-guide.com/wp-content/uploads/2021/08/V838-Monocerotis.webp 502w, https://www.constellation-guide.com/wp-content/uploads/2021/08/V838-Monocerotis-275x300.webp 275w" sizes="(max-width: 500px) 100vw, 500px" /></noscript> <p id="caption-attachment-16859" class="wp-caption-text">In January 2002, a dull star in an obscure constellation suddenly became 600,000 times more luminous than our Sun, temporarily making it the brightest star in our Milky Way galaxy. The mysterious star, called V838 Monocerotis, has long since faded back to obscurity. But observations by NASA’s Hubble Space Telescope of a phenomenon called a “light echo” around the star have uncovered remarkable new features.

Called the Cone Nebula (NGC 2264) — so named because, in ground-based images, it has a conical shape — this giant pillar resides in a turbulent star-forming region. This picture, taken by the newly installed Advanced Camera for Surveys (ACS) aboard NASA’s Hubble Space Telescope, shows the upper 2.5 light-years of the nebula, a height that equals 23 million roundtrips to the Moon. The entire nebula is 7 light-years long. The Cone Nebula resides 2,500 light-years away in the constellation Monoceros. Radiation from hot, young stars [located beyond the top of the image] has slowly eroded the nebula over millions of years. Ultraviolet light heats the edges of the dark cloud, releasing gas into the relatively empty region of surrounding space. There, additional ultraviolet radiation causes the hydrogen gas to glow, which produces the red halo of light seen around the pillar. A similar process occurs on a much smaller scale to gas surrounding a single star, forming the bow-shaped arc seen near the upper left side of the Cone. This arc, seen previously with the Hubble telescope, is 65 times larger than the diameter of our solar system. The blue-white light from surrounding stars is reflected by dust. Background stars can be seen peeking through the evaporating tendrils of gas, while the turbulent base is pockmarked with stars reddened by dust. Over time, only the densest regions of the Cone will be left. Inside these regions, stars and planets may form. Image: NASA, H. Ford (JHU), G. Illingworth (UCSC/LO), M.Clampin (STScI), G.

This strikingly detailed new Hubble image reveals how, when seen from space, the nebula, rather than being rectangular, is shaped like an X with additional complex structures of spaced lines of glowing gas, a little like the rungs of a ladder. The High Resolution Channel of the NASA/ESA Hubble Space Telescope’s Advanced Camera for Surveys captured this view of HD 44179 and the surrounding Red Rectangle nebula — the sharpest view so far. Red light from glowing Hydrogen was captured through the F658N filter and coloured red. Orange-red light over a wider range of wavelengths through a F625W filter was coloured blue.
