Center of the Trifid Nebula (M20) - Center of the Trifid Nebula - The Trifid Nebula (M20) is located between 5000 and 10,000 years - light of the Earth in the constellation of Sagittarius. This image obtained by the Hubble space telescope shows the center of this nebula. A group of bright stars is visible in the center of the image near the dark bands of interstellar dust. These stars are young, blue, massive and extremely hot stars; they are O-type stars and the radiation they emit influence the evolution and structure of the nebula. Trifid Nebula, also known as Messier 20 and NGC 6514, lies within our own Milky Way Galaxy between 5000 and 10 000 light - years from Earth, in the constellation Sagittarius. This image from the Hubble Space Telescope offers a close - up view of the center of the Trifid Nebula, near the intersection of the dust bands, where a group of recently formed, massive, bright stars is easily visible. These stars, which astronomers classify as belonging to the hott

Saturn by Voyager 2 - Rings in fake colors - Composition differences within Saturn's rings. Voyager 2 - Image in false colors made by the Voyager 2 probe on August 17, 1981 at a distance of 8.9 million km from the planet. This image has been reconstructed from 3 black and white photos taken through the UV, green and orange filters. The contrasts were exaggerated. The different colors correspond to differences in the chemical composition of the particles that make up the rings. Possible variations in chemical composition from one part of Saturn's ring system to another are visible in this Voyager 2 picture as subtle color variations that can be recorded with special computer - processing techniques. This highly enhanced color view was assembled from clear, orange and ultraviolet frames obtained Aug. 17 from a distance of 8.9 million kilometers (5.5 million miles). In addition to the previously known blue color of the C - ring and the Cassini Division, the picture shows additional color

Nebula NGC 3372 in the Carene - The Carina nebula, NGC 3372 - The Carene nebula is located about 7000 years from the Earth. It is home to many hot stars, including the star Eta Carinae in the centre of the nebula. Image obtained by Siding Spring's 3.9m telescope. The brightest part of the Milky Way, as seen by the unaided eye, lies in the southern constellation Carina. Here there are an unusually large number of young, hot stars. Their radiation is rich in energetic ultraviolet light. Many of these stars were born within the spectacular Carinae nebula, seen here. The nebula is a cloud of glowing gas composed mostly of hydrogen. It excited by ultrviolet light from the embedded stars. This dostictive emission radiation is responsible for the red colour. About a quarter of the nebula is made of helium gas, the second most abundant element in the universe after hydrogen, and all the other chemical elements account for only a few percent of the total mass. The brightest star in the nebula i

Nebulae B175 and VDB 152 in Cephee - Dark nebula B175 and reflection nebula VDB 152 - Located about 1400 years ago - light in the constellation Cephee, a large dust trail leads to a bluish nebula. This is the dark nebula, Barnard 175, which faces the nebula by reflexion VDB 152 (Ced 201). The reflection nebula vdB 152 is really very faint. It lies about 1400 light - years away, along the northern Milky Way in the constellation Cepheus. Near the edge of a large molecular cloud, pockets of cosmic dust in the region block light from background stars or scatter light from the embedded bright star (top) giving parts of the nebula a characteristic blue color. Ultraviolet light from the star is also thought to cause a dim reddish luminescence in the nebular dust. Although stars do form in molecular clouds, this star seems to have only accidentally wandered into the area, as its measured velocity through interstellar space is very different from the cloud's velocity

Saturn above the clouds of Titan - Illustration - Saturn from atop Titan's hydrocarbon haze - Artist's view of the planet Saturn view 80 km above the surface of his satellite Titan. In the plane of the rings of the planet appear from left to right the satellites Enceladus, Dione, Tethys and Rhea. Saturn and its rings would be a majestic sight lording over Titan's hydrocarbon haze. The viewpoint is from 50 miles above Titan's surface and three - quarters of a million miles away from Saturn itself. Four of Saturn's smaller satellites can also be seen along the ring plane: left to right are Enceladus, Dione, Tethys and Rhea. Technically, the orange clouds mark the beginning of Titan's condensate haze, which consists of ethane, methane, nitrogen, and a variety of hydrocarbons known collectively as tholin. These gases and hydrocarbons extend upward another 250 miles, resulting in a bluish, earthlike sky, albeit darker due to Titan's great distance from the Sun. Tholin is created by the inte

Nebula N159 in the Great Magellan Cloud - N159 star forming region in Large Magellanic Cloud (LMC): N159 is a star-forming region located in the galaxy of the Great Magellan Cloud. Image obtained by the Hubble Space Telescope (HST) - This shot from the NASA/ESA Hubble Space Telescope shows a maelstrom of glowing gas and dark dust within one of the Milky Way's satellite galaxies, the Large Magellanic Cloud (LMC). This stormy scene shows a stellar nursery known as N159, an HII region over 150 light-years across. N159 contains many hot young stars. These stars are emitting intense ultraviolet light, which causes nearby hydrogen gas to glow, and torrential stellar winds, which are carving out ridges, arcs, and filaments from the surrounding material. At the heart of this cosmic cloud lies the Papillon Nebula, a butterfly-shaped region of nebulosity. This small, dense object is classified as a High-Excitation Blob, and is thought to be tightly linked to the early stages of massive star form

The little - known nebula IRAS 05437+2502 billows out among the bright stars and dark dust clouds that surround it in this striking image from the Hubble Space Telescope. It is located in the constellation of Taurus (the Bull), close to the central plane of our Milky Way galaxy. It appears to be a small, rather isolated, region of star formation and one might assume that the effects of fierce ultraviolet radiation from bright young stars probably were the cause of the eye - catching shapes of the gas. However, the bright boomerang - shaped feature may tell a more dramatic tale. The interaction of a high velocity young star and the cloud of gas and dust may have created this unusually sharp - edged bright arc.

This is the most detailed view to date of the entire surface of the dwarf planet Pluto, as constructed from multiple NASA Hubble Space Telescope photographs taken from 2002 to 2003. Hubble's view isn't sharp enough to see craters or mountains, if they exist on the surface, but Hubble reveals a complex - looking and variegated world with white, dark - orange, and charcoal - black terrain. The overall color is believed to be a result of ultraviolet radiation from the distant Sun breaking up methane that is present on Pluto's surface, leaving behind a dark, molasse - colored, carbon - rich residue.

Saturn and Mimas seen by the Cassini probe 18/01/2005 - Saturn and Mimas seen by Cassini spacecraft Jan. 18 2005 - The Mimas satellite photographed in front of Saturn by the Cassini probe on 18 January 2005 at a distance of 1.4 million km from the planet. The shadow of Saturn's rings is projected on the planet. Mimas drifts along in its orbit against the azure backdrop of Saturn's northern latitudes in this true color view. The long, dark lines on the atmosphere are shadows cast by the planet's rings. Saturn's northern hemisphere is presently relatively cloud - free, and rays of sunlight take a long path through the atmosphere. This results in sunlight being scattered at shorter (bluer) wavelengths, thus giving the northernmost latitudes their bluish appearance at visible wavelengths. At the bottom, craters on icy Mimas (398 kilometers, or 247 miles across) give the moon a dimpled appearance. Images taken using infrared (930 nanometers), green (568 nanometers) and ultraviolet (338 nano

On the night of August 4, 2005, an amateur astronomer and supernovae discoverer Reverend Robert Evans discovered a supernova just North of this galaxy. This supernova is classified as a somewhat unusual type Ia supernova, caught probably 10 days before it reached its maximum brightness. Such a supernova is thought to be the result of the explosion of a small and dense star - a white dwarf - inside a binary system. As its companion was continuously spilling matter onto the white dwarf, the white dwarf reached a critical mass, leading to a fatal instability. NGC 1559 is a SBc (s) - type spiral galaxy located a

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.

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).

Planetary nebula M57 (NGC 6720) in Lyra - The Ring nebula M57 in Lyra - The planetary nebula of Lyra (M57) is located about 2000 years - light from Earth. A planetary nebula is a gas shell from a small late-life star whose heart collapsed to become a white dwarf and expelled the outer layers of its matter. Image obtained by the Hubble Space Telescope and the Large Binocular Telescope. In this composite image, visible - light observations by Nasa's Hubble Space Telescope are combined with infrared data from the ground - based Large Binocular Telescope in Arizona to assemble a dramatic view of the well - known Ring Nebula. Called a planetary nebula, the Ring Nebula is the glowing remains of a Sun - like star. The object is tilted towards Earth so that astronomers see the ring face - on. The Hubble observations reveal that the nebula's shape is more complicated than astronomers thought. The blue gas in the nebula's center is actually a football - shaped structure that pierces the red doug

The Hubble Space Telescope's Near Infrared Camera and Multi - Object Spectrometer (NICMOS) has captured a glimpse of a brief stage in the burnout of NGC 7027, a medium - mass star like our sun. THE INFRARED VIEW - - The composite color image of NGC 7027 (on the left) is among the first data of a planetary nebula taken with NICMOS. This picture is actually composed of three separate images taken at different wavelengths. The red color represents cool molecular hydrogen gas, the most abundant gas in the universe. The image reveals the central star, which is difficult to see in images taken with visible light. Surrounding it is an elongated region of gas and dust cast off by the star. This gas (appearing as white) has a temperature of several tens of thousands of degrees Fahrenheit. The object has two “” cones”” of cool molecular hydrogen gas (the red material) glowing in the infrared. The gas has been energized by ultraviolet light from the star - a process known as fluorescence. Most of

Enceladus, Saturn's satellite, seen by Cassini - Saturn's moon Enceladus from Cassini - Mosaic of false-coloured images obtained by the Cassini probe during the flight over this satellite on 11 August 2008. The image shows a fractured region in the southern hemisphere of the satellite. This mosaic of Saturn's moon Enceladus provides broad regional context for the ultra - sharp, close - up views Nasa's Cassini spacecraft acquired minutes earlier, during its flyby on Aug. 11, 2008. This false - color mosaic combines Imaging Science Subsystem (ISS) narrow - angle camera images obtained through ultraviolet, green, and near - infrared camera filters. Areas that are greenish in appearance are believed to represent deposits of coarser grained ice and solid boulders that are too small to be seen at this scale, but which are visible in the higher resolution views, while whitish deposits represent finer grained ice. The mosaic shows that coarse - grained and solid ice are concentrated along vall

Tethys, Saturn satellite, seen by the Cassini probe - Saturn's moon Tethys seen by Cassini spacecraft: The Tethys satellite photographed by the Cassini probe on 11 April 2015 has a distance of 53,000 km from the satellite. Tethys is about 1070 km in diameter. - This enhancement-color mosaic of Saturn's icy moon Tethys shows a range of features on the moon's trailing hemisphere. Tethys is tidally locked to Saturn, so the trailing hemisphere is the side of the moon that always faces opposite its direction of motion as it orbits the planet - Images taken using clear, green, infrared and ultraviolet spectral filters were combined to create the view, which highlights subtle color differences across Tethys' surface at wavelengths not visible to human eyes. The moon's surface is fairly uniform in natural color - The color of the surface changes conspicuously across the disk, from yellowish hues to nearly white. These broad color changes are affected by a number of external processes. First, S

Eagle Nebula (IC 4703) in the Snake - detail - Young stars in the Eagle nebula - Detail on young stars located in the north - west part of the Eagle Nebula (M16). Image obtained by the Hubble Space Telescope. This picture shows the northwestern part of the Eagle nebula (M16), well away from the centre, and features some very bright young stars that formed from the same cloud of material. These energetic toddlers are part of an open cluster and emit ultraviolet radiation that causes the surrounding nebula to glow. The star cluster is very bright and was discovered in the mid - eighteenth century. The nebula, however, is much more elusive and it took almost a further two decades for it to be first noted by Charles Messier in 1764. Although it is commonly known as the Eagle Nebula, its official designation is Messier 16 and the cluster is also named NGC 6611. One spectacular area of the nebula (outside the field of view) has been nicknamed The Pillars of Creation”” ever since the Hubble S
