![]() ![]() It will take tens of millions of years more for them to reach full “starhood".Īlso known as the Orion nebula, Messier 42 (M42) is located at a distance of around 1344 lightyears from the Earth, and it is also the nearest star-forming region to our planet. Although fairly bright, they are not yet hot enough for nuclear fusion reactions to having begun in their cores. This vast nebula is around 1600 lightyears away from Earth, and it is home to a number of T Tauri-type stars that are believed to have formed within the last 10 million years. In 1780, Pierre Méchain detected the presence of a reflection nebula in the Orion that spanned across a diameter of 10 lightyears. The Orion constellation also contains three such objects that go by the names Messier 78 (a reflection nebula), Messier 43 (De Mairan's Nebula), and Messier 42 (the Orion Nebula). These objects were later named collectively as Messier objects. His initial catalog consisted of 41 entries, and his final catalog, published in 1781, contained 103 entries, along with notes on several other objects he had found. So in 1764, he started to keep a catalog of these objects, later helped by his friend and colleague Pierre François Méchain, in order to avoid mistaking them for comets. The repeated occurrence of such objects was acting as a distraction for Messier in his search for comets. When French astronomer Charles Messier started looking for comets in the late 1700s, he came across various other celestial objects. Messier objects in the Orion constellation Messier 78. The Orion constellation can be easily seen during the daytime between May and July, whereas the months between November and February are best for observing the constellation during the nights. Spread over an area of about 594 square degrees, Orion is bordered by the constellations of Monoceros, Taurus, Lepus, Gemini, and Eridanus.īelgian astronomer Eugène Joseph Delporte defined the boundaries of Orion, along with the other constellations, in 1930. It is among the 15-star configurations that intersect the celestial equator. with the right ascension of five hours and declination of five degrees. It is best viewed at latitudes between 85° and -75°. The Orion constellation is located in the southwestern sky if you are in the Northern Hemisphere or the northwestern sky if you are in the Southern Hemisphere. Where exactly can you find the Orion constellation? The Trapezium inside Orion. The constellation is named after the huntsman Orion, a character mentioned in Greek mythology, and this is why it is also referred to as the hunter constellation. The closest star to our planet in the constellation is Bellatrix which is around 244 lightyears away, and the farthest star is Alnilam, located at a distance of 1,344 lightyears. The distance between Earth and the Orion constellation ranges from 243 to 1360 lightyears away. Orion is the 26th-largest constellation in our sky, it is home to seven main stars and numerous other celestial objects. ![]() Orion is among the most visible constellations from the Earth, and it is home to some of the brightest stars of our sky such as Rigel and Betelgeuse. Some believe that this actually represents the first-star chart, suggesting that humans knew about this vast celestial constellation of stars located on the celestial equator and containing some of the brightest stars in the night sky, around 10 of which are now thought to host exoplanets. The tablet contained a carving that depicts a man-like figure with arms and legs outstretched in the same pose as the stars of the constellation Orion. In 1979, a small ivory tablet dating back to between 32,500 and 38,000 years was discovered in a cave located in the Ach Valley, Germany. ![]()
