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 Rosette Nebula in the Unicorn - The Rosette Nebula and NGC 2244 cluster - The Rosette Nebula is a vast cloud of dust and gas located about 5500 years from Earth. Towards the center of the nebula, a cluster of blue stars, NGC 2244 formed less than a million years ago. Image obtained from the 1.2m Schmidt UK telescope of Siding Spring. The Rosette Nebula exhibits a striking circular symmetry which gives it the appearance of a partly opened rose, an allusion further enhanced by the rich red hues seen in this colour photograph. Near the centre of the nebula is a cluster of blue stars catalogued as NGC 2244. These stars are responsible for making the nebula visible and for creating the hollowed - out central cavity. This cluster of stars formed from the gas which now surrounds it less than a million years ago and is thus very young on the cosmic timescale. The gas and dust at the centre of the nebula have been forced away from the bright stars by radiation pressure and the intense stell

The Formation of the Earth - Artist's View - Meteorite strike on infant Earth - The Earth was formed 4.6 billion years ago from a gigantic cloud of gas and dust. These dust accreted to form our planet; it was subjected to a large bombardment of meteorites. A molten, infant Earth is impacted by an object about 10 miles in diameter, releasing 200 million times a much energy as the largest manmade explosion. While this collision appears negligible when compared to the scars of much larger encounters, a similar impact four billion years later may have resulted in the extinction of the dinosaurs. The Earth accrued the majority of its mass during the 100 million years following the formation of the Sun, a period referred to as the cosmic bombardment. During this era of frequent impacts and radioactive heating, the entire Earth remained molten long enough for the heavy metals iron and nickel to settle to the center of the Earth while lighter silicates floated to the surface. Today, over four

Supernova 1987A in the Great Magellan Cloud View by HST - Glittering stars and wisps of gas create a breathtaking backdrop for the self - destruction of a massive star, called supernova 1987A, in the Large Magellanic Cloud, a nearby galaxy. Astronomers in the Southern hemisphere witnessed the brilliant explosion of this star on Feb. 23, 1987. Shown in this NASA Hubble Space Telescope image, the supernova remnant, surrounded by inner and outer rings of material, is set in a forest of ethereal, diffuse clouds of gas. This three - color image is composed of several pictures of the supernova and its neighboring region taken with the Wide Field and Planetary Camera 2 in Sept. 1994, Feb. 1996 and July 1997. The many bright blue stars nearby the supernova are massive stars, each more than six times heftier than our Sun. With ages of about 12 million years old, they are members of the same generation of stars as the star that went supernova. The presence of bright gas clouds is another sign of

Birth of stars in the nebula NGC 3372 - Star formation in the Carina Nebula - Detail of the Carene nebula (NGC 3372) obtained by the Hubble space telescope. The image shows a column of gas eroded by ultraviolet radiation emitted by young stars. Jets are also visible, showing the presence of emerging stars. NGC 3372 is located about 7500 light years away from Earth. The colors used in this image correspond to the emissions of different gases: sulfur in red, hydrogen in green and oxygen in blue. The NASA Hubble Space Telescope photograph captures the chaotic activity atop a three - light - year - tall pillar of gas and dust that is being eaten away by the brilliant light from nearby bright stars. The pillar is also being assaulted from within, as infant stars buried inside it fire off jets of gas that can be seen streaming from towering peaks. This turbulent cosmic pinnacle lies within a tempestuous stellar nursery called the Carina Nebula, located 7,500 light - years away in the souther

Star formation in the nebula NGC 2467 - Star - forming region NGC 2467 - Star formation in the nebula NGC 2467, located approximately 17,000 years ago - light from Earth in the southern constellation of Stern. Image obtained by the Hubble Space Telescope in 2004. A colourful star - forming region is featured in this stunning new NASA/ESA Hubble Space Telescope image of NGC 2467. Looking like a roiling cauldron of some exotic cosmic brew, huge clouds of gas and dust are sprinkled with bright blue, hot young stars. Strangely shaped dust clouds, resembling spilled liquids, are silhouetted against a colourful background of glowing. Like the familiar Orion Nebula, NGC 2467 is a huge cloud of gas - - mostly hydrogen - - that serves as an incubator for new stars. It is located about 17,000 light years away in the southern constellation of Puppis. This picture was created from images taken with the Wide Field Channel of the Advanced Camera for Surveys through three different filters (F550M, F6

Star field in the constellation Sagittarius - Scattered stars in Sagittarius: Stars in Sagittarius seen by the space telescope Hubble. This colourful and star-studded view of the Milky Way galaxy was captured when the NASA/ESA Hubble Space Telescope pointed its cameras towards the constellation of Sagittarius (The Archer). Blue stars can be seen scattered across the frame, set against a distant backdrop of red-hued cosmic companions. This blue litter most likely formed at the same time from the same collapsing molecular cloud. The colour of a star can reveal many of its secrets. Shades of red indicate a star much cooler than the Sun, so either at the end of its life, or much less massive. These low-mass stars are called red dwarfs and are thought to be the most common type of star within the Milky Way. Similarly, brilliant blue hues indicate hot, young, or massive stars, many times the mass of the Sun. A star's mass decides its fate; more massive stars burn brightly over a short lifesp

Cepheide RS Puppis - Cepheides are very bright variable stars that serve as cosmic beacons to measure the distance of nearby galaxies. Their pulse period is measured and their absolute luminosite is calculated. By comparing the result to their apparent luminosite in the sky, they can be calculated accurately. Here, the space telescope photographed one of the brightest cepheids, RS Puppis (in the center of the image), located 6500 years - light in the southern constellation of the Puppi. The bright southern hemisphere star RS Puppis, at the center of the image, is swaddled in a gossamer cocoon of reflective dust illuminated by the glittering star. The super star is ten times more massive than our Sun and 200 times larger. RS Puppis rhythmically brightens and dims over a six - week cycle. It is one of the most luminous in the class of so - called Cepheid variable stars. Its average intrinsic brightness is 15,000 times greater than our Sun's luminosity.

Their pulse period is measured and their absolute luminosite is calculated. By comparing the result to their apparent luminosite in the sky, they can be calculated accurately. Here, the space telescope photographed one of the brightest cepheids, RS Puppis (in the center of the image), located 6500 years - light in the southern constellation of the Puppi. The bright southern hemisphere star RS Puppis, at the center of the image, is swaddled in a gossamer cocoon of reflective dust illuminated by the glittering star. The super star is ten times more massive than our Sun and 200 times larger. RS Puppis rhythmically brightens and dims over a six - week cycle. It is one of the most luminous in the class of so - called Cepheid variable stars. Its average intrinsic brightness is 15,000 times greater than our Sun's luminosity.

Galaxy cluster Abell 1689 - Gravitational lenses in Abell 1689 galaxy cluster - Galaxy cluster Abell 1689 is about 2.2 billion years ago - light in the constellation of the Virgin. This image shows, by a gravitational mirage effect, the deformed image of many galaxies located behind the cluster. Near infrared and visible image obtained by the Hubble space telescope. 34 hours of installation. This new Hubble image shows galaxy cluster Abell 1689. It combines both visible and infrared data from Hubble's Advanced Camera for Surveys (ACS) with a combined exposure time of over 34 hours (image on left over 13 hours, image on right over 20 hours) to reveal this patch of sky in greater and striking detail than in previous observations. This image is peppered with glowing golden clumps, bright stars, and distant, ethereal spiral galaxies. Material from some of these galaxies is being stripped away, giving the impression that the galaxy is dripping, or bleeding, into the surrounding space. Also

Pioneer Plate - The Pioneer Plate - The Pioneer 10 and Pioneer 11 probes have embarked on a plate, called the Pioneer Plate, containing a message intended for potential aliens. On this engraved metal plate are depicted a naked man and woman, the location of our Sun as well as 14 pulsars, the trajectory of the probe in the solar system... Pioneer 10 was launched on 3 March 1972 with as its first destination, the Jupiter Planet, which it flew over on 3 December 1973; it was the first space probe to approach this planet; it was also the first space probe to leave the solar system. The Pioneer F spacecraft, destined to be the first man made object to escape from the solar system into interstellar space, carries this pictorial plaque. It is designed to show scientifically educated inhabitants of some other star system, who might intercept it millions of years from now, when Pioneer was launched, from where, and by what kind of beings. The design is etched into a 6 inch by 9 inch gold - anod

Star Formation in the DR21 Region - Star Formation in the DR21 Region - This star formation region is about 6200 years old - light. Hidden in light visible by interstellar dust, this region rises in infrared light. Gas filaments appear in red; they emphasize the presence of aromatic polycyclic hydrocarbons (PAH); they are organic molecules composed of carbon atoms and hydrogen that could be the germs on which the first bricks of life appeared. Composite image in different wavelengths obtained by the Spitzer space telescope; in blue the visible light, in yellow and red the infrared light. Hidden behind a shroud of dust in the constellation Cygnus is a stellar nursery called DR21, which is giving birth to some of the most massive stars in our galaxy. Visible light images reveal no trace of this interstellar cauldron because of heavy dust obscuration. This image from Nasa's Spitzer Space Telescope allow us to peek behind the cosmic veil and pinpoint one of the most massive natal stars yet

Markarian Galaxy 817 - Galaxy Markarian 817 - The spiral galaxy Markarian 817 is located 430 million light years ago in the constellation Dragon. This galaxy houses in its heart a supermassive black hole. Image obtained by the Hubble Space Telescope on August 2, 2009. Rings of brilliant blue stars encircle the bright, active core of this spiral galaxy, whose monster black hole is blasting material into space at over 14 million kilometers per hour. Viewed nearly face - on, the galaxy, called Markarian 817, shows intense star - forming regions and dark bands of interstellar dust along its spiral arms. Observations by the new Cosmic Origins Spectrograph (COS) aboard the NASA/ESA Hubble Space Telescope captured the powerful outflow of material from this galaxy. The COS spectrum of Markarian 817 highlights the outflow's dynamic nature. A gas cloud containing hydrogen that was detected in Hubble data taken in 1997 does not appear in the COS observation because the cloud has apparently been d

Central region of the Tarantula Nebula - The Tarantula Nebula - The Tarantula Nebula (or 30 Dorada) is the largest star-forming region of the Magellan Cloud. It is located 170,000 light years ago in the constellation Dorado (southern hemisphere). At the center of this nebula, the open cluster of R136 stars, clusters of young, hot and massive stars, aged just 5 million years. Mosaic of 5 images obtained by the Hubble space telescope. Vast Star - Forming Region 30 Doradus Nasa's Hubble Space Telescope has snapped a panoramic portrait of a vast, sculpted landscape of gas and dust where thousands of stars are being born. This fertile star - forming region, called the 30 Doradus Nebula, has a sparkling stellar centerpiece: the most spectacular cluster of massive stars in our cosmic neighborhood of about 25 galaxies. The mosaic picture shows that ultraviolet radiation and high - speed material unleashed by the stars in the cluster, called R136, are weaving a tapestry of creation and destruct

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
