Spiral Galaxy M51 in Hunting Dogs - Spiral galaxy M51 in Canes Venatici - The spiral galaxy M51 (NGC 5194) is located about 31 million years ago - light from Earth. This galaxy is double; two galaxies interact: the largest, NGC 5194, the smallest NGC 5195. Image obtained with an 80 cm telescope in September 2011. M51 (NGC 5194) is located 31 million light - years away in the constellation Canes Venatici (the Hunting Dogs). It was one of the first discoveries made by Charles Messier in 1773, and it was the first galaxy where spiral structure was observed, by Lord Rosse in 1845. A faint companion galaxy, NGC 5195, seen here to the left of M51, is interacting with M51. The image was taken with a 32 - inch telescope in september 2011

Spiral Galaxy M66 in the Lion - Spiral galaxy M66 in Leo - M66 (NGC 3627) is a spiral galaxy located at a distance of about 35 million years - light. M66, with its neighbors M65 and NGC 3628, forms a remarkable triplet of galaxies, called the Lion Triplet or the M66 Group. NGC 3627, also known as Messier 66, is a beautiful spiral with a well - developed central bulge. It also displays large - scale dust lanes. The galaxy forms, together with its neighbours M65 and NGC 3628, the so - called “Leo Triplet””; they are located at a distance of about 35 million light - years. M 66 is the largest of the three. Its spiral arms appear distorted and displaced above the main plane of the galaxy. The asymmetric appearance is most likely due to gravitational interaction with its neighbours

Spiral galaxy M74 - UV composite - visible - Spiral galaxy M74 in visible and UV - Image of the spiral galaxy M74 (NGC 628) made by Astro satellite - 1. This galaxy is about 80,000 light years and is 30 million light years apart. In this composite image the visible light is in red, in blue the ultraviolet light. Located in the constellation of Pisces the Fish, the telescopic object Messier 74 is one of the finest examples of a giant spiral galaxy seen nearly face - on. In this composite image of M74, the visible - light emission is represented in red, while the UV emission is shown in blue - white tints. Newborn hot stars and associated nebulosity dominate the near - UV emission. The concentration of this starbirth activity along the spiral arms is indicative of global dynamic processes at work. M74 estimated distance is 24 million light years

Open cluster of Pleiades - Open cluster of Pleiades - The north is at top. The Pleiades star cluster, also known as the Seven Sisters and Messier 45, is one of the brightest and famous star clusters visible in the northern hemisphere. It consists of about 500 bright, hot, young stars that were all born at the same time between 75 and 150 million years ago within a large cloud of dust and gas. The cluster contains many stars, of which only a handful are commonly visible to the naked eye. The blue haze that accompanies them is due to very fine dust which still remains and preferentially reflects the blue light from the stars. This star cluster lies some 440 light years away from the Earth, in the constellation of Taurus. This image is based on data acquired by the Oschin Telescope at the Mount Palomar Observatory

Spiral Galaxy M83 in Hydra - Spiral galaxy M83 in Hydra - The galaxy M83 (NGC 5236) is located about 15 million years away from Earth. This galaxy is intermediate between a classic spiral and a barree spiral. Image obtained from the 3.9m telescope of Siding Spring, Australia. M83 is thought to be very like our own Galaxy, the Milky Way, but seen from above one of its poles and at a distance of about 15 million light years. Composed of billions of stars and huge clouds of dust and gas, this object is one of the finest examples of a spiral galaxy and shows a concentration of older, yellow stars in its central nucleus with younger, blue stars and patchy red clouds of glowing gas and dark dust lanes in the trailing spiral arms. The massive blue stars occasionally explode as supernovae; at least eight have been seen in Messier 83 in the last 70 years

Globular cluster M13 - Hercules cluster - M13 The Great Globular Cluster in Hercules - M13 (NGC 6205), extends for about 150 years - light and is 22,000 years - light from Earth in the constellation of Hercules. It contains hundreds of thousands of stars. Lower left is the galaxy NGC 6207. M13 is the Great Globular Cluster in the constellation of Hercules. It is one of the largest and most beautiful globular clusters visible from the northern hemisphere. At magnitude 5.8, M13 is visible to the keen unaided eye at a dark - sky observing site. It is located about 25,000 light years away. It has an apparent angular diameter of 15 to 25 arc minutes, depending on the size of the telescope used to observe it. This corresponds to a real size of about 145 light years. It contains hundreds of thousands of stars. M13 was discovered in 1714 by Edmond Halley and catalogued by Charles Messier in 1764. Galaxy NGC 6207 can be seen at the lower left. North is to the left in this image

Spiral Galaxy M83 in Hydra - Spiral galaxy M83 in Hydra - The galaxy M83 (NGC 5236) is located about 15 million years away from Earth. This galaxy is intermediate between a classic spiral and a barree spiral. Image obtained from the 3.9m telescope of Siding Spring, Australia. M83 is thought to be very like our own Galaxy, the Milky Way, but seen from above one of its poles and at a distance of about 15 million light years. Composed of billions of stars and huge clouds of dust and gas, this object is one of the finest examples of a spiral galaxy and shows a concentration of older, yellow stars in its central nucleus with younger, blue stars and patchy red clouds of glowing gas and dark dust lanes in the trailing spiral arms. The massive blue stars occasionally explode as supernovae; at least eight have been seen in Messier 83 in the last 70 years

Constellation Cancer - Cancer constellation - At the top right, the star Pollux des Gemeaux. Cancer (the Crab) is a rather small constellation of 506 square degrees without any bright stars, however, the stick figure above strongly hints at a crab - like shape. The ecliptic runs through the middle of the main stars, which makes it one of the 12 zodiacal constellations. It is best seen in the early evening in March. The most obvious feature in the image above is the large open cluster Messier 44, also known as Praesepe, which appears to the unaided eye as a fuzzy patch. It is easly resolved into numerous faint stars in binoculars, hence its popular name, the Beehive cluster. Although inconspicuous, the constellation gave its name to the Tropic of Cancer. In ancient times Cancer was where the Sun appeared at its maximum mid - day elevation at the time of the (northern) summer solstice. Because of the precession of the equinoxes the northern summer solstice now occurs when the Sun is in T

M87 is the brightest radio source in the constellation, it is also called Virgo A. Image made with Siding Spring's 3.9m telescope. Messier 87 (NGC 4486) is at the heart of the Virgo cluster and has a mass many times that of the Milky Way, itself no lightweight. Unlike our galaxy however, M87 is an elliptical galaxy. Though it appears more - or - less spherical on this photograph, a deep image shows it to be markedly elongated. Also unlike the Milky Way, M87 contains relatively little gas and dust. It is composed mainly of cool stars, which gives it a yellowish colour, in contrast to the blue of spiral galaxies. Despite the lack of star - forming materials, M87 is not a quiescent backwater.

The M16 star cluster is a cluster of young stars formed about 2 million years ago in the Eagle nebula, IC 4703. These stars are much warmer than the Sun and can be 30 times more massive. Image made with Siding Spring's 3.9m telescope. There are few clearer examples anywhere of the intimate relationship between dust, gas and young stars than M16. We see a young cluster of stars (NGC 6611) which formed about 2 million years ago, illuminating a cloud of hydrogen gas. The gas is also dusty, and in places the dust is dense enough to prevent starlight from reaching the gas and making it glow with its distinctive red hue. The luminous hydrogen provides a vivid background against which are seen numerous dark lanes and discrete globules of dust.

Detail of the Eagle Nebula (M16) dans le serpent/HST - This eerie, dark structure, resembling an imaginary sea serpent's head, is a column of cool molecular hydrogen gas (two atoms of hydrogen in each molecule) and dust that is an incubator for new stars. The stars are embedded inside finger - like protrusions extending from the top of the nebula. Each “” fingertip”” is somewhat larger than our own solar system. The pillar is slowly eroding away by the ultraviolet light from nearby hot stars, a process called “” photoevaporation””. As it does, small globules of especially dense gas buried within the cloud is uncovered. These globules have been dubbed “” Eggs”” - - an acronym for “” Evaporating Gaseous Globules””. The shadows of the Eggs protect gas behind them, resulting in the finger - like structures at the top of the cloud. Forming inside at least some of the Eggs are embryonic stars - - stars that abruptly stop growing when the Eggs are uncovered and they are separated from the lar
