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

Hourglass Nebula in M8 - The Hourglass Nebula in M8, NGC 6523 - View of the Hourglass Nebula in the heart of the Lagoon Nebula (M8/NGC 6523). Located in Sagittarius, at a distance of 5800 light years, it is a region of star formation whose gases are excited mainly by two massive supergeant stars Herschel 36 and 9 Sagittarii. Image made with the 1.5m Danish telescope of La Silla in Chile. At the heart of the Lagoon Nebula in Sagittarius lies the diminutive Hourglass Nebula. Its gases are excited primarily by two massive O-type supergiants designated Herschel 36 and 9 Sagittarii. These two stars lie to the west of NGC 6530 and are separated from it by a dark lane which divides the nebula like a black lagoon, giving it its name. Twisted funnel shaped clouds are visible close to the illuminating stars, especially Herschel 36. The twists are due to shear forces between the hot excited gases at the surface and the cold interior of the clouds. These stars are probably less than 10,000 years o

View of the nebula of the Lagoon (M8/NGC 6523). Located in Sagittarius, at a distance of 5800 light years, it is visible to the naked eye in good conditions. It is a star-forming region illuminated by several large O-type stars that belong to the open cluster NGC 6530 visible in the center of the image. The brightest part of the nebula is called the hourglass nebula whose gases are excited mainly by two massive supergeant stars Herschel 36 and 9 Sagittarii. M8 has at least 60 Giant B stars, 3 to 4 times more than the Orion nebula - The Lagoon nebula (M8), can be visible to the unaided eye as a small bright patch above the large Sagittarius star cloud in the Milky Way. The Lagoon nebula is a star-forming region about 5800 light years from us. The nebula is illuminated by several O-type giants within the open cluster NGC 6530 near the center of the nebula. The brightest part of the nebula is known as the “hourglass nebula”” and its gases are excited primarily by two massive O-type superg

Halley's comet - Halley's comet - Halley's comet seen on April 10, 1986 in Peru. Glowing at 6th magnitude, Comet Halley exhibits a faint 90 degree wide fan - shaped dust tail. The dust tail is very difficult to see in this photo because it is superimposed on the bright background of the Milky Way. The blue ion tail is a bit easier to see, trailing off to the upper right of the coma. This photo was taken on April 10 1986, the day of Halley's closest approach to the Earth. Stars appear as streaks because the photo was guided on the comet which was moving rapidly relative to the starry background

Galaxies NGC 5078 and IC 879 in Hydra - Galaxies NGC 5078 and IC 879 in Hydra - NGC 5078 is a spiral galaxy located about 95 million years ago - light. A small galaxy, IC 879, at the bottom of the picture, is probably interacting with it. Image obtained with a 50 cm telescope, composite of several poses. NGC 5078 is a lenticular (lens - shaped) galaxy crossed by a distinct dusty band which is seen against the bright background of the galaxy itself. The dust lane is warped and broadened, probably by interaction with the faint companion galaxy IC 879, which is itself distorted into an 'S' shape by the interaction. The slightly bluish colour of parts of the fainter galaxy is suggestive of star formation, probably triggered by the interaction. Encounters between galaxies such as this are common, and often lead to them merging into a single entity. It is likely that the dust lane of NGC 5078 is the remnant of a dusty spiral which fell into it long ago. The galaxies are about 95 million ligh

Spiral galaxy NGC 1566 in the bream - The Seyfert Galaxy NGC 1566: NGC 1566 is a spiral galaxy located about 40 million light years ago. Its core is very bright. It is an active galaxy called Seyfert, which probably houses a black hole in its heart. Image obtained with the Hubble telescope - NGC 1566 is a galaxy located approximately 40 million light-years away in the constellation of Dorado (The Dolphinfish). NGC 1566 is an intermediate spiral galaxy, meaning that while it does not have a well defined bar-shaped region of stars at its centre - like barred spirals - it is not quite an unbarred spiral either (heic9902o). The small but extremely bright nucleus of NGC 1566 is clearly visible in this image, a telltale sign of its membership of the Seyfert class of galaxies. The centres of such galaxies are very active and luminous, emitting strong bursts of radiation and potentially harbouring supermassive black holes that are many millions of times the mass of the Sun.

Image obtained from the 3.9m telescope of Siding Spring This is an unusual annular planetary nebula in Norma. The nebula itself appears quite small at a little over an arc minute in diameter, while its central star is a magnitude 14 white dwarf. This object is unusual because those planetaries that are not bipolar are more or less spherical shells of material thrown off by the central star as it undergoes an internal rearrangement. We often see them as thick annuli because we look through a greater thickness at the edge of the shell. However, Shapley 1 seems to be a true torus, a doughnut - shaped ring of material that we happen to see face - on around the central star. Sp - 1 is about 1000 light years distant

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.

Supernova Remnants SNR B0509 - 67.5 - Supernova Remnant SNR B0509 - 67.5 - SNR B0509 - 67.5 (or SNR 0509) is the rest of a star explosion in the galaxy of the Great Magellan Cloud. This 23-year bubble - light of diameter extends at a speed of 18 million km/h. A composite of visible images and X-rays obtained by the Hubble Space Telescope (HST) in 2006 and 2010 and by the Chandra satellite. This delicate shell, photographed by the NASA/ESA Hubble Space Telescope, appears to float serenely in the depths of space, but this apparent calm hides an inner turmoil.

Galaxies cluster 1E 0657 - 556 - Dark matter in the galaxy cluster 1E 0657 - 556 - Composite view of the galaxy cluster 1E 0657 - 556 visible and X-rays. The hot gas that surrounds this galaxy cluster, detects in X-rays by the Chandra satellite, is visible in pink on this image. The galaxy cluster, photographed by the Magellan telescope and the Hubble space telescope, appears in the background. By studying the mass of this cluster, astronomers were able to determine that most of this mass was concentrated not in the hot gas detected by Chandra but in the blue coloured areas here, suggesting the existence of dark matter. This composite image shows the galaxy cluster 1E 0657 - 556, also known as the “” bullet cluster.”” This cluster was formed after the collision of two large clusters of galaxies, the most energetic event known in the universe since the Big Bang. Hot gas detected by Chandra telescope in X - rays is seen as two pink clumps in the image and contains most of the “” normal,”

Galaxy NGC 4650A in Centaurus - Galaxy NGC 4650A in Centaurus - The polar ring galaxy NGC 4650A is located about 130 million years away from Earth. The host galaxy is surrounded by a polar ring shaped like gas and stars. This type of galaxy is rarely observed. This image was obtained by the ANTU telescope of the VLT in 1998. This is a colour photo from the VLT that shows NGC 4650A, a member of the so - called Centaurus chain of galaxies in the southern constellation of that name. NGC 4650A is a complex system that is located at a distance of about 130 million light - years. There are two main components, a lenticular - shaped galaxy (of type S0), surrounded by a knotty extended ring - like distribution of stars, dust and gas, almost perpendicular to each other. The stars in the central, structureless region and the material (stars, gas, and dust) in the outer disk rotate in two different planes that are almost perpendicular to each other. The observed motions indicate the presence of a

Interacting galaxies Markarian 533 - Interacting galaxies Markarian 533 - The galaxy NGC 7674 (Markarian 533 or Arp 182) is located about 400 million years ago - light from Earth in the constellation Pegase. It is the most important member of a group of galaxies called Hickson 96 (HCG 96). This spiral galaxy seen from the front is in interaction with other companion galaxies. It has an active core. Image obtained by the Hubble Space Telescope on June 9, 2002. NGC 7674 (seen just above the center), also known as Markarian 533, is the brightest and largest member of the so - called Hickson 96 compact group of galaxies, consisting of four galaxies. This stunning Hubble image shows a spiral galaxy nearly face - on. The central bar - shaped structure is made up of stars. The shape of NGC 7674, including the long narrow streamers seen to the left of and below the galaxy can be accounted for by tidal interactions with its companions. NGC 7674 has a powerful active nucleus of the kind known as

Field of distant galaxies - Distant galaxies - Image of distant galaxies obtained by the Hubble space telescope in the furnace constellation. 7500 galaxies, some of which are more than 13 billion years old - light are visible on this image. Some closer galaxies also appear. This image covers a field equivalent to one third of a full moon. This image, taken by Nasa's Hubble Space Telescope, was made from mosaics taken in September and October 2009 with the newly installed Wide Field Camera 3 (WFC3) and in 2004 with the Advanced Camera for Surveys (ACS). The view covers a portion of the southern field of a large galaxy census called the Great Observatories Origins Deep Survey (GOODS), a deep - sky study by several observatories to trace the formation and evolution of galaxies. The final image combines a broad range of colors, from the ultraviolet, through visible light, and into the near - infrared. The image reveals galaxy shapes that appear increasingly chaotic at each earlier epoch, a
