Galaxy NGC 1232 in Eridan - Spiral galaxy NGC 1232 in Eridanus - Image of the large spiral galaxy NGC 1232 obtained by the VLT in September 1998. In the arms, many star-forming regions are visible, while in the center of the galaxy, older resident stars. Note the presence on the left of a dwarf galaxy. NGC 1232 is located about 100 million years ago - light. The field of this photo is about 200,000 years old - light, double our galaxy, the Lactee Way. NGC 1232 is located 20 degrees south of the celestial equator, in the constellation Eridanus (The River). The distance is about 100 million light - years. The edge of the field shown here corresponds to about 200,000 lightyears, or about twice the size of the Milky Way galaxy. This image of the large spiral galaxy NGC 1232 was obtained on September 21, 1998, by the FORS instrument at VLT. The colours of the different regions are well visible: the central areas contain older stars of reddish colour, while the spiral arms are populated by y

Spiral Galaxy M33 in the Triangle - Spiral galaxy M33 in Triangulum - The Galaxy of the Triangle (M33, NGC598) is located about 2 million years ago - light from Earth. It belongs to the local group, just like our galaxy or Andromede galaxy. In red, the star-forming regions appear, especially at the top left NGC 604 one of the largest and most active star-forming regions. It extends over 150 years of light. Image obtained from the Isaac Newton telescope of La Palma. M33 is a large, almost face - on spiral galaxy about 2.5 million light years distant in the northern constellation of Triangulum. It is a member of the 'Local Group' of galaxies, which is dominated by the Milky Way and M31. Like M31, M33 is approaching the Milky Way at a velocity of about 180km/s. Although the total light M33 galaxy is that of a star of magnitude 5.3, its large diameter makes it hard to see. However, despite its low surface brightness, this galaxy was among the first to be identified as a 'spiral nebula' by

Interacting Galaxies Arp 240 - Interacting galaxies Arp 240 - The galaxy Arp 240 is located about 300 million light years away from Earth in the constellation of the Virgin. Composed of spiral galaxies NGC 5257 and NGC 5258, this interacting system presents important star formations. The two galaxies contain a supermassive black hole in the centre. Image obtained by the Hubble Space Telescope on 20 December 2001. NGC 5257/8 (Arp 240) is an astonishing galaxy pair, composed of spiral galaxies of similar mass and size, NGC 5257 and NGC 5258. The galaxies are visibly interacting with each other via a bridge of dim stars connecting the two galaxies, almost like two dancers holding hands while performing a pirouette.

Orion's Nebula - The Great Nebula in Orion - Located 1500 years ago - light, Orion's Nebula is the closest region of star formation in the Sun. Image obtained with the 1.2m Schmidt UK Telescope from Siding Spring. To the eye, the nebula appears as a misty patch around the central star of the line of three which form Orion's sword. Binoculars or a modest telescope will show that these three 'stars' are loose groups of several individuals some of which can be seen in this photograph. The central group of stars, the Trapezium cluster is hidden in the glow of the Orion Nebula in this photograph, but these stars are responsible for producing the nebula. It is the high concentration of dust and gas in this part of the sky which has resulted in the formation of the stars, so the Orion nebula is no random association of bright stars and dusty gas. At a distance of 1500 light years, the Orion nebula is the nearest star - forming region to the Sun

Orion Nebula (M42 - 43) - The Orion Nebula - Located 1500 years ago - the Orion Nebula is the closest region to the formation of stars of the Sun. Image obtained with Siding Spring's 3.9m telescope. The Orion Nebula is famous for a number of reasons. It is the nearest bright nebula to us and can be seen with the naked eye. Its brightness led to it being the first nebula ever photographed (in 1882) and its proximity (1500 light years) means that we know more about it than any other star - forming region. It is also in a very active stage of star formation and it is perfectly placed for us to explore the intimate details of the birth of stars. The inner regions are glowing mainly in the red light of excited hydrogen, which together with some green emission from oxygen give the centre of the nebula a yellowish colour. The energy for this spectacular display comes from the small cluster of stars in the brightest part of the nebula. Three, five - minute exposures were used to make this pict

Although the total light M33 galaxy is that of a star of magnitude 5.3, its large diameter makes it hard to see. However, despite its low surface brightness, this galaxy was among the first to be identified as a 'spiral nebula' by Lord Rosse in the 1840s.

This image is a composite of X-ray images (blue) obtained by the Chandra Space Telescope and visible (green and red) by the Hubble Space Telescope. The study of very hot gas observed in X-ray allows us to better understand the star formation activity within this nebula. NGC 604, is one of the largest known seething cauldrons of star birth in a nearby galaxy. NGC 604 is similar to familiar star - birth regions in our Milky Way galaxy, such as the Orion Nebula, but it is vastly larger in extent and contains many more recently formed stars. This monstrous star - birth region contains more than 200 brilliant blue stars within a cloud of glowing gases some 1,300 light - years across, nearly 100 times the size of the Orion Nebula. The bright stars in NGC 604 are extremely young having formed a mere 3 million years ago. The most massive stars

Nebula NGC 2170 in Unicorn - Nebula NGC 2170 in Monoceros - Nebula by reflexion located in the constellation Unicorn. This rich collection of predominantly reflection and sparse emission nebulosity exists in the western part of a vast star forming region known as the Mon R 2 association. The “” R”” designation stands for reflection and indicates an association of stars illuminating reflection nebulae. Most of the members of Mon R 2 are type B stars located along an east - west line stretching across 2 degrees of the winter sky, situated about 8 degrees east of the Orion Nebula. The Mon R 2 association resides at a distance of 830 pc and formed about 6 to 10 million years ago along the edge of the Mon R2 molecular cloud. NGC2170 is a common nebula imaged and yet with long exposures it takes on a whole new look. Many of the nebulae seen here appear to be uncataloged and not previously imaged.

This image of the Whirlpool Galaxy, taken in January 2005 with the Advanced Camera for Surveys aboard Nasa's Hubble Space Telescope, illustrates a spiral galaxy's grand design, from its curving spiral arms, where young stars reside, to its yellowish central core, a home of older stars. The galaxy is nicknamed the Whirlpool because of its swirling structure

Nebulae NGC 6334 and NGC 6357 in Scorpio - Nebulae NGC 6334 and NGC 6357 in Scorpius - These nebulae are located approximately 5500 years - light from Earth. Image made with the 1.2m Telescope of Schmidt UK from Siding Spring. The star - forming nebulae NGC 6334 and NGC 6357 show no evidence of a blue component in their colour - indeed, the blue - light plate used in these 3 - colour pictures had no nebulous image at all - nor is there any obvious sign of the bright blue stars normally found in these objects. They are excellent examples of the phenomenon known as 'interstellar reddening', the selective removal of blue light by minute particles of dust in the line of sight. This accounts for both the ruddy hue and apparent absence of blue stars. The hot stars are present but only some of the red part of their light is seen so they are not conspicuous. These nebulae are quite nearby (5500 light years) but located close to the Galactic plane and are buried in the dust of the Milky Way. Ca

Spiral galaxy M81 infrared view - Spiral galaxy M81 seen in infrared - View obtained by Spitzer space telescope in different wavelengths. In infrared, Spitzer sees dust rather than stars, thus improving our understanding of star formation. The M81 spiral galaxy is located 12 million light years away from Earth. Its arms are home to star-forming regions while its core is surrounded by much older yellow stars. Located in the northern constellation of Ursa Major (which also includes the Big Dipper), this galaxy is easily visible through binoculars or a small telescope. M81 is located at a distance of 12 million light - years. These infrared images were obtained by Spitzer's infrared array camera. At these wavelengths, Spitzer sees the dust, rather than the stars, within the disc of silicates and carbonaceous grains. It is well - mixed with gas, which is best seen at radio wavelengths, to form the essential ingredients for future star formation

Galaxy M82 in the Great Bear seen in X-rays - The galaxy M82 seen in X-ray - Image obtained by Chandra in X-rays, reveals a cloud (in red) of very hot gas of several million degres emitted from the central regions of the galaxy. M82 is an irregular galaxy distant about 12 million years - light from Earth. Its nucleus, which appears to have suffered from the passage of the neighbouring galaxy M81, is in a phase of violent star activity. Its central regions are rich in star formation. These hot stars blow a stellar wind that becomes a very violent galactic wind. Chandra's X - ray image reveals gas that has been heated to millions of degrees by the violent outflow of matter blasting out of the galaxy. The eruption can be traced back to the central regions of the galaxy where stars are forming at a furious rate, some 10 times faster than in the Milky Way Galaxy.

Nebula N70 in the Great Magellan Cloud - The N 70 nebula in Large Magellanic Cloud (LMC) - The Henize 70 nebula extends for about 400 years - light, it is located in the Great Magellan Cloud. In the center, a small group of very massive and extremely hot stars, stars of Wolf - Rayet. Image obtained by Siding Spring's 3.9m telescope. At the centre of this remarkable bubble - like nebula nebula is a small group of extremely hot stars. Some of these stars are rapdly losing mass and have stellar winds blowing from their surfaces with velocities that approach 4000 kilometers per second. Such stars are known as Wolf - Rayet stars and are found in galaxies capable of forming massive stars. There are many such stars in the Large Magellanic Cloud (LMC) but not all of them are associated with distinctive nebulae. The outward flowing streams of energetic particles from Wolf - Rayet (and other energetic stars) eventually interact with the relatively stationary interstellar medium pervading the LMC

Spiral galaxies NGC 3314 A and B in Hydra - Galaxy pair NGC 3314 in Hydra - NGC 3314 is a pair of spiral galaxies distant about 140 million years - Earth light. These galaxies are not interacting but just perfectly aligned in front of each other from Earth. Through an extraordinary chance alignment, a face - on spiral galaxy lies precisely in front of another larger spiral. This line - up provides us with the rare chance to visualize dark material within the front galaxy, seen only because it is silhouetted against the object behind it. NGC 3314 lies about 140 million light - years from Earth, in the direction of the southern hemisphere constellation Hydra. The bright blue stars forming a pinwheel shape near the center of the front galaxy have formed recently from interstellar gas and dust. In many galaxies, interstellar dust lies only in the same regions as recently formed blue stars. However, in the foreground galaxy, NGC 3314a, there are numerous additional dark dust lanes that are

Spiral galaxy NGC 6503 in the Dragon - Spiral galaxy NGC 6503 in Draco - The dwarf spiral galaxy NGC 6503 is located about 17 million years ago - light from Earth. It spans 30,000 light years and shows many star-forming regions. Image obtained by the Hubble Space Telescope. Fresh starbirth infuses the galaxy NGC 6503 with a vital pink glow in this image from the NASA/ESA Hubble Space Telescope. This galaxy, a smaller version of the Milky Way, is perched near a great void in space where few other galaxies reside. This new image from Hubble's Advanced Camera for Surveys displays, with particular clarity, the pink - colored puffs marking where stars have recently formed in NGC 6503's swirling spiral arms. Although structurally similar to the Milky Way, the disc of NGC 6503 spans just 30 000 light - years, or just about a third of the size of the Milky Way, leading astronomers to classify NGC 6503 as a dwarf spiral galaxy. NGC 6503 lies approximately 17 million light - years away in the co
