Carene Constellation and Southern Constellation - Constellation of Carina and southern constellations - The constellation of Carene, the Great Magellan Cloud, the southern Celestial pole, and the star Canopus. This part of the sky is best seen in the early evening between April and June. Carina the Keel, is a remnant of Argo Navis, a giant mythical sailing vessel afloat on the southern Milky Way, described elsewhere. The constellation is a delight for southern hemisphere observers, with many star clusters and nebulae visible in binoculars or modest telescopes. Some of these are quite spectacular in a large telescope. The second brightest star in the sky, Canopus (a Car) is here as is Eta Carinae, one of the most massive and unstable stars in the Galaxy. Eta is hidden in the most conspicuous nebula in Carina, NGC 3372, the Great Carina nebula. This photograph also shows the location of the south celestial pole and the Large Magellanic Cloud as well as several complete or almost complete

Nebula Trifide (M20) in the constellation Sagittarius - Trifid nebula (M20) in Sagittarius - View of the Trifide nebula (M20/NGC 6514) located in the constellation Sagittarius between 5000 and 10,000 years - light from Earth. Image obtained by Siding Spring's 3.9m telescope. The spectacular Trifid nebula (Messier 20) is one of the best known in the sky. It is a striking mixture of brilliant red light emitted from excited hydrogen gas and the soft blue glow of a reflection nebula. The blue arises from starlight, scattered by dust particles between the stars. The size of the particles is minute, similar to those of smoke, which also has a bluish hue. However, the scattered light is not a pure blue, and if we see it through a medium that is yellow (i.e. absorbs blue light) some green colouration remains. This effect can be seen in some of the darker parts of the faint reflection nebula that surrounds the Trifid, where partial absorption of light by foreground dust provides a yellow 'filte

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

Mars and Zodiacal Light - The Zodiacal Light with Mars - In the middle up, the bright spot is the planet Mars, in the constellation Gemeaux. Below, the zodiac light. The zodiacal light comes from the reflection of the Sun's light on the countless interplanetary dust; it draws the plan of the Solar System. September 20, 2009. The Zodiacal light is visible here as a large diffuse triangular - shaped cone of light rising along the ecliptic, which is tilted a bit to the right. Its base stretches from Leo on the left to the head of Hydra on the right. It goes up through Cancer and into Gemini where it crosses the Milky Way. The planet Mars was also located in Gemini when this photo was taken. The Zodiacal light is composed of fine particles of dust in orbit around the Sun. It is visible because of sunlight scattered by the particles. These particles have sizes between a couple of micrometers and a few millimeters. From the mid - northern latitudes, the Zodiacal light is most easily visible

Satellite Herschel - Illustration - Artist's view of the European satellite Herschel. The Herschel Space Observatory, scheduled to launch in 2009, will study in the infrared the formation of galaxies, stars and planetary systems. This satellite measures nearly 7 metres high by 4.3 metres wide and weighs 3.25 tonnes. Its telescope has a 3.5-meter mirror, making it the largest mirror ever made for a scientific space mission. Herschel will orbit around Lagrange 2, approximately 1.5 million kilometres from Earth. ESA's Herschel Space Observatory (formerly called Far Infrared and Submillimetre Telescope or FIRST) will solve the mystery of how stars and galaxies were born. Objects such as other planetary systems, or processes like the birth of galaxies in the early universe, can best be studied with infrared space telescopes in space. This is the reason for Esa's Herschel. ESA's Herschel Space Observatory will be bigger and better than any of its predecessors. Moreover, it will observe at wa

Lambeosaurs - Lambeosaurus riverside - A six-ton male lambeosaur (lambeosaurus) rises from a potential threat. In the background a female and her juvenile drink the water of the river. The lambeosaurs were herbivorous dinosaurs of the cretace. In this scene evoking the landscape of Montana in the United States, 75 million years ago, are also depicted now extinct Tremskya ferns as well as flowering magnolias similar to those we know today. Note also the presence of some birds. In a scene 75 million years ago from what's now Montana, a six ton male Lambeosaurus rears onto its massive hind legs in response to a possible threat, while a female and juvenile Lambeosaurus drink near the river's edge. Lambeosaurus was a plant-eating dinosaur known for its distinctive hollow cranial crest, which in the best-known species resembled a hatchet. The purpose of the crest is unknown. Also featured here are Late Cretaceous Period flora including the now extinct tree fern Tempskya and species of flower

This artist's impression shows how the planet inside the disc of Beta Pictoris may look. Only 12 million years old, or less than three - thousandths of the age of the Sun, Beta Pictoris is 75% more massive than our parent star. It is located about 60 light - years away towards the constellation of Pictor (the Painter) and is one of the best - known examples of a star surrounded by a dusty debris disc. Earlier observations showed a warp of the disc, a secondary inclined disc and comets falling onto the star, all indirect, but tell - tale signs that strongly suggested the presence of a massive planet. Observations done with the NACO instrument on Eso's Very Large Telescope in 2003, 2008 and 2009, have proven the presence of a planet around Beta Pictoris.

Vesuvius, one of the best known volcanoes in the world primarily for the eruption that buried the Roman city of Pompeii, is shown in the center of this radar image. The central cone of Vesuvius is the dark purple feature in the center of the volcano. This cone is surrounded on the northern and eastern sides by the old crater rim, called Mt. Somma. Recent lava flows are the pale yellow areas on the southern and western sides of the cone. Vesuvius is part of a large volcanic zone which includes the Phalagrean Fields, the cluster of craters seen along the left side of the image. The Bay of Naples, on the left side of the image, is separated from the Gulf of Salerno, in the lower left, by the Sorrento Peninsula. Dense urban settlement can be seen around the volcano.

Southern Crown Nebula - The Corona Australis nebula (NGC 6726 - 27 - 29) - R Coronae Australis is a region of star formations visible in the southern hemisphere. It is located about 500 light years away from Earth. Image made with Siding Spring's 3.9m telescope. This spectacular reflection nebula is the result of a few bright stars caught up in a large, dusty cloud. If that is all there was here, this region would be considered to be like the Pleiades, an accidental association of dust and stars. However, there are features here that show the dark cloud to be an active star forming nebula, though most of the action is hidden from view. The peculiar yellowish curved streak near the two bright reflection nebulae surround an intriguing object best seen in infrared light, R CRA, a young star still accreting interstellar material on to its surface. It seems to be the source of two compact but distinctly red patches which are Herbig - Haro objects, often the first visible signs of star forma

The most persistent legend seems to be that he died from the sting of a giant scorpion, which was placed in the sky so that Orion sets as the Scorpius rises, in an eternal chase across the sky. The momorable outline of the Hunter proudly bestrides the celestial equator and is equally visible from both hemispheres. The distinctive, equally spaced line of stars of Orion's Belt are more or less on the equator and are framed by quartet of bright and colourful stars. More subtle is Orions short sword, hanging from his belt. Under dark skies or in binoculars the central 'star' is distinctly misty. This is the famous Orion nebula, one of many well known telescopic objects that fill

This image features the Las Vegas, Nevada metropolitan area, located near the southern tip of the state within the Mohave Desert of the southwestern USA. While the city of Las Vegas proper is famous for its casinos and resort hotels, the metropolitan area includes several other incorporated cities and unincorporated (not part of a state - recognized municipality) areas. Astronauts on board the International Space Station observe and photograph numerous metropolitan areas when they are illuminated by sunlight, but the extent and pattern of these areas is perhaps best revealed by the city lights at night. The surrounding dark desert presents a stark contrast to the brightly lit, regular street grid of the developed metropolitan area.

Towards the center of the image, a small nebula emitted, Sh2 - 83. Little Fox Constellation. Brocchi's Cluster (also known as the Coathanger or Collinder 399) is an asterism located in the constellation Vulpecula. It was first described by the Persian astronomer Al Sufi in his Book of Fixed Stars in 964 and was independently rediscovered by Giovanni Hodierna in the seventeenth century. In the 1920s, D. F. Brocchi, an amateur astronomer and chart maker for the American Association of Variable Star Observers, created a map of this object for use in calibrating photometers. The asterism is made up of ten stars ranging from fifth to seventh magnitude which form the conspicuous Coathanger, a straight line of six stars with a “” hook””” of four stars on the south side.

Tethys, Saturn satellite, seen by the Cassini probe - Saturn's moon Tethys seen by Cassini spacecraft - The southern pole of the Tethys satellite photographed by the Cassini probe on September 24, 2005. Mosaic of nine images. With this full - disk mosaic, Cassini presents the best view yet of the south pole of Saturn's moon Tethys. The giant rift Ithaca Chasma cuts across the disk. Much of the topography seen here, including that of Ithaca Chasma, has a soft, muted appearance. It is clearly very old and has been heavily bombarded by impacts over time. Many of the fresh - appearing craters (ones with crisp relief) exhibit unusually bright crater floors. The origin of the apparent brightness (or “” albedo”) contrast is not known. It is possible that impacts punched through to a brighter layer underneath, or perhaps it is brighter because of different grain sizes or textures of the crater floor material in comparison to material along the crater walls and surrounding surface.

The field measures 27.5 x 26.5 arcmin2., North is up and East is left. The two best known satellite galaxies of the Milky Way, the Magellanic Clouds, are located in the southern sky at a distance of about 170,000 light - years. They host many giant nebular complexes with very hot and luminous stars whose intense ultraviolet radiation causes the surrounding interstellar gas to glow. The intricate and colourful nebulae are produced by ionised gas that shines as electrons and positively charged atomic nuclei recombine, emitting a cascade of photons at well defined wavelengths. Such nebulae are called “” H II regions””, signifying ionised hydrogen, i.e. hydrogen atoms that have lost one electron (protons). Their spectra are characterized by emission lines whose relative intensities carry usefu
