Several parts of it — the famous Orion Nebula, for one — can be seen without binoculars. The nebula is one of the brightest ones in the sky and can be seen without binoculars. It has a visual magnitude of 4.

Messier 42 is the nearest known region of massive star formation to the solar system. It is part of the Orion Molecular Cloud Cluster. The Orion Nebula contains the Trapezium, or the Orion Trapezium Cluster , a very young open cluster easily recognizable by its four brightest stars, which form a trapezium-shaped asterism.

The Trapezium Cluster is a young, tight open star cluster located in the centre of the Orion Nebula. It is 47 arc seconds in size and has an apparent magnitude of 4. The cluster was first discovered by Galileo Galilei on February 4, He drew three of the stars A, C and D , and the fourth one was added by observers in By , eight stars were discovered in the cluster.

The brightest five emit most of the light that illuminates the surrounding nebula. The Trapezium Cluster is easily identifiable in the sky by the asterism formed by the four brightest stars, A, B, C and D.

Schneider, E. Young, G. Rieke, A. Cotera, H. Chen, M. Rieke, R. Wong Rice University. The brightest and most massive star in the cluster, component C, is Theta-1 Orionis C, a blue main sequence star belonging to the spectral class O6pe V.

The star has a visual magnitude of 5. It is one of the most luminous stars known, with an absolute magnitude of Theta-1 Orionis C is also the star with the highest surface temperature of any star that is visible to the unaided eye: 45, K. Charles Messier later designated the nebulosity Messier 43 and included it in his catalogue. It has an apparent magnitude of 9. The nebula is located about seven arc minutes north of the Trapezium cluster.

Messier 78 is a reflection nebula in Orion. The nebula surrounds two 10th magnitude stars and can easily be found in a small telescope. It also contains some 45 T Tauri type variables, young stars still in the process of formation.

The Horsehead Nebula, also known as Barnard 33 , is a famous dark nebula in Orion. It is located south of Alnitak, in the bright emission nebula IC The Horsehead Nebula is approximately 1, light years distant. It was discovered by the American astronomer Williamina Fleming in The nebula got the name Horsehead because of the shape formed by the dark dust clouds and gases, one that resembles the head of a horse when observed from Earth.

The nebula has an an apparent magnitude of 5 and is about 1, light years distant from the solar system. It is believed to have originated in a supernova event about two million years ago.

Barnard, the astrophotographer who photographed the nebula and published a description in It appears as a large arc centred on Messier 42 the Orion Nebula.

The loop is believed to be ionized by the stars located in the Orion Nebula. The Flame Nebula is an emission nebula in Orion. It has a visual magnitude of 2. Alnitak emits ultraviolet light into the nebula, knocking electrons away from the hydrogen gas clouds inside the nebula, and the glow of the nebula is the result of the electrons and ionized hydrogen recombining. NGC is an open star cluster, approximately 3, light years away from the solar system.

It has an apparent magnitude of 5. The cluster was originally discovered by the Italian astronomer Giovanni Batista Hodierna in the midth century and then later independently spotted by William Herschel on October 15, It is sometimes called The 37 Cluster because it resembles the number NGC is just under seven arc minutes in diameter and consists of about 30 stars, which are only eight million years old.

The brightest one has an apparent magnitude of 6. NGC is a reflection nebula in Orion constellation. The nebula is notable for being one of the brightest sources of fluorescent molecular hydrogen. It is lit by the B star HD , the most luminous star lighting the surface of the molecular cloud Lynds Horsehead Nebula, or Barnard 33 , and one of the largest reflection nebulae in the sky. It is four light years wide.

NGC can be found a third of a degree from the Horsehead Nebula. It is It is associated with the open cluster NGC , also located in Orion. The nebula is approximately 6, light years distant. It is also known as the Monkey Head Nebula because of its unusual shape in wide field images.

The problem is that star formation is a very inefficient process; most of the ingredients to make stars are wasted as the cloud of gas and dust, or nebula, gradually disperses. In NGC , the rate at which the nebula disperses is further speeded up by the presence of hot young stars, which create high velocity winds that blow the gas outwards.

These fiery youngsters also flood the surrounding gas with intense radiation, making it glow brightly, creating the brilliant scene captured here. This picture shows only part of the nebula, where dark dust clouds are strikingly silhouetted against the glowing gas. Orion Constellation. Facts, location and map Orion is the 26th constellation in size, occupying an area of square degrees. Hubble Space Telescope images reveal about 3, stars in the Orion Nebula alone, some of which could be as little as 10, years old.

The visible nebula is a bubble of turbulent gas that is energized by the Trapezium, a cluster of hot, bright stars at its center. Ultraviolet energy from the stars strips electrons from atoms in the nebula. When the electrons link up with new atoms, the atoms emit light.

The process of starbirth continues today, with several hundred dense blobs of gas and dust collapsing to make new stars. In addition, planetary systems appear to be taking shape around many of the newborn stars. Not all of them will survive the birth process, though, because radiation from the cluster's hot young stars is eroding the planet-making materials around many of the stars.

This group, when viewed with the unaided eye or through binoculars, looks like a large fuzzy patch, but when viewed through a small telescope it appears as two nebulae - one large and one considerably smaller. The larger is M42 and when viewed with a small telescope, you will find a group of four young, bright, hot white stars called the Trapezium near the centre. Under ideal seeing you can find two more stars in this group.

Though some of these targets can be seen with the naked eye, for a better view we recommend using binoculars or a telescope.

If you need equipment, our best binoculars and best telescopes guides may help. Magnitude: An object's magnitude tells you how bright an object is as it appears from the Earth. In astronomy, magnitudes are represented on a numbered scale.

Quite confusingly the lower the number, the bright the object. Right ascension RA : Right ascension is to the sky what longitude is to the surface of the Earth, corresponding to east and west directions. Measured in hours, minutes and seconds since, as Earth rotates, we see different parts of the sky through the night.

Declination Dec : Tells you how high your object will rise in the sky. Like Earth's latitude, declination measures north and south. Its units are degrees, arcminutes and arcseconds. There are 60 arcmins in a degree and 60 arcsecs in an arcmin.

Casually glancing below the three stars of Orion's belt, you should be able to make out the Orion Nebula as a smudge in a dark, light pollution-free sky with your naked eye. The Orion Nebula — a formation of dust, hydrogen, helium and other ionized gases rather than a star — is the middle "star" in Orion's sword, which hangs off of Orion's Belt. It is one of the brightest nebulae in the sky, according to NASA. The Horsehead Nebula is a tricky target to find, but it is not impossible.

The nebula can be found just south of the easternmost star in Orion's Belt. The shape of the nebula is forged by radiation from the surrounding stars.
