Barree spiral galaxy NGC 1365 in the Furnace - Barred spiral galaxy NGC 1365 in Fornax - NGC 1365 is a barree spiral galaxy that extends over 200,000 years - light. Located 60 million years ago - light, it belongs to the cluster of galaxies of the Furnace. Image obtained by Siding Spring's 3.9m telescope. NGC 1365, the largest spiral in the southern constellation of Fornax, is located at a distance of about 60 million light years. This beautiful galaxy is about as massive as the Milky Way, itself a substantial galaxy. Not much is known about how galaxies take on their beautiful forms, but a good deal is known about their internal organisation. The obvious 'bar' has the nucleus of the galaxy at its hub and is surrounded by masses of cooler stars that appear yellow on colour photographs. The bar itself is also yellowish, and has distinct dust lanes but it terminates abruptly in slender, curved arms that are lit by blue stars and the pink star - forming regions from which they spring

Spiral Galaxy M51 in Hunting Dogs - Spiral galaxy M51 in Canes Venatici - The spiral galaxy M51 (NGC 5194) is located about 31 million years ago - light from Earth. This galaxy is double; two galaxies interact: the largest, NGC 5194, the smallest NGC 5195. Image obtained by the Hubble Space Telescope in 2005. M51 (NGC 5194) is located 31 million light - years away in the constellation Canes Venatici (the Hunting Dogs). The Whirlpool's beautiful face - on view and closeness to Earth allow astronomers to study a classic spiral galaxy's structure and star - forming processes. 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

Cometary blood cell CG4 in the stern - CG4, a cometary blood cell in Puppis - Cometary blood cells are small clouds of isolated gases. The latter, called CG4, is located about 1300 light years ago in the constellation of Pupus. Its head is 1.5 years light and its tail extends for 8 years. This cloud is a star-forming region. A spiral galaxy seen by the slice (ESO 257 - 19) is visible at the top left. It is located 100 million years later. Cometary globules are typically characterized by dusty heads and elongated tails. These features cause cometary globules to have visual similarities to comets, but in reality they are very much different. Cometary globules are frequently the birthplaces of stars, and many show very young stars in their heads. The reason for the rupture in the head of this object is not completely known. The galaxy to the left of center is an edge - on spiral galaxy, ESO 257 - 19, 100 million light years distant and only placed near CG4 by chance superposition

Interacting galaxies in the Austral Fish - Interacting galaxies in Piscis Austrinus - The galaxies NGC 7173 (middle left), NGC 7174 (middle right) and NGC 7176 (bottom right) photographed here by the Hubble Space Telescope (HST), belong to a cluster of galaxies called Hickson Compact Group 90 (HCG 90), located about 100 million years ago lights in the constellation of Southern Fish. NGC 7173 and NGC 7176 are two elliptical galaxies while NGC 7174 is a spiral galaxy deformed by the gravitational forces exerted by its neighbors. The three pictured galaxies - - NGC 7173 (middle left), NCG 7174 (middle right) and NGC 7176 (lower right) - - are part of the Hickson Compact Group 90, named after astronomer Paul Hickson, who first catalogued these small clusters of galaxies in the 1980s. NGC 7173 and NGC 7176 appear to be smooth, normal elliptical galaxies without much gas and dust. In stark contrast, NGC 7174 is a mangled spiral galaxy, barely clinging to independent existence as it is ripped

Star cluster in the nebula NGC 3603 - Star cluster in NGC 3603 nebula - Cluster of young stars in the nebula NGC 3603, located about 20,000 years ago - light from Earth in the southern constellation of Carene. Image obtained by the Hubble Space Telescope in August and December 2009. NGC 3603 is a prominent star - forming region located in the Carina spiral arm of the Milky Way, about 20,000 light - years away from our Solar System. This image from the NASA/ESA Hubble Space Telescope shows a young star cluster surrounded by a vast region of dust and gas. Most of the bright stars in the image are hot blue stars whose ultraviolet radiation and violent winds have blown out an enormous cavity in the gas and dust enveloping the cluster. This Hubble Space Telescope image was captured in August 2009 and December 2009 with the Wide Field Camera 3 in both visible and infrared light, which trace the glow of sulfur, hydrogen, and iron

This image from the NASA/ESA Hubble Space Telescope shows a young star cluster surrounded by a vast region of dust and gas. Most of the bright stars in the image are hot blue stars whose ultraviolet radiation and violent winds have blown out an enormous cavity in the gas and dust enveloping the cluster. This Hubble Space Telescope image was captured in August 2009 and December 2009 with the Wide Field Camera 3 in both visible and infrared light, which trace the glow of sulfur, hydrogen, and iron

Tarantula Nebula (NGC 2070) in the river bream - The Tarantula Nebula, around the 30 Dor cluster - The Tarantula Nebula (or 30 Bream) is the largest star-forming region of the Great 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 hot and massive stars. Image obtained with Siding Spring's 3.9m telescope. This object is the only extra - galactic nebula which can be seen with the unaided eye. It is a faint patch of light at the eastern end of the Large Magellanic Cloud, 170,000 light years distant. A small telescope reveals narrow spindly tendrils of glowing gas which have been likened to the legs of a spider. The 'body' of the spider is the bright nebula seen at the centre of the photograph, while at its core is an extremely dense clump of very hot stars, until recently thought to a single, unusually massive star known as 30 Doradus.

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 has been carefully processed to reveal the many faint and dusty nebulae in this regio

This wide - angle picture of the Orion region has been made to reveal the extensive network of very faint filaments which are traceable over most of the constellation. These faint features are optical evidence of a substantial dark cloud of molecular gas and dust which dominate at radio wavelengths. Where hot stars are closely associated with the molecular cloud, a bright nebula appears. By far the most conspicuous of these is the Orion Nebula, M42. This spectacular object is so bright that its light is reflected from filaments of the dark cloud some distance away.

Spiral galaxy NGC 2997 in the Pneumatic Machine - Spiral galaxy NGC 2997 in Antlia - NGC 2997 is a spiral galaxy distant about 55 million years - light. NGC 2997 seems to be a galaxy seen from the front but in reality is inclined by about 45 degrees. Its arms are home to large star-forming regions while its core is surrounded by much older yellow stars. The disc of NGC 2997 is inclined at about 45 degrees to our line of sight, revealing its internal structure and giving the galaxy an oval appearance. Like most spirals, the galaxy has two prominent spiral arms, which appear to originate in the yellow nucleus, are peppered with bright red blobs of ionised hydrogen which are similar to regions of star formation in our own Milky Way. Within these gas clouds are produced the hot blue stars which generate most of the light in the arms of the galaxy. A much older population of yellowish stars are concentrated around the nucleus.

Star Formation in the dwarf galaxy NGC 1569 - Starburst galaxy NGC 1569 - NGC 1569 is a dwarf irregular galaxy in the constellation Giraffe. The Hubble space telescope measured its distance with precision, placing it 11 million years - light from Earth, or 4 million years - light beyond the distance previously established by astronomers. This new measure explains better why this galaxy has a particularly high star formation rate. It resides among a group of galaxies that by gravity compresses its gas, thus creating a hundred times more stars than in our own galaxy. NGC 1569 is located in the middle of a group of about 10 galaxies centered on the spiral galaxy IC 342. Gravitational interactions among the group's galaxies may be compressing gas in NGC 1569 and igniting the star - birthing frenzy. The galaxy is forming stars at a rate more than 100 times higher than the rate in the Milky Way. This high star - formation rate has been almost continuous for the past 100 million years. Thanks

Planets, including those like our own Earth, form from epic collisions between asteroids and even bigger bodies, called proto-planets. Sometimes the colliding bodies are ground to dust, and sometimes they stick together to ultimately form larger, mature planets. This artist's conception shows one such smash-up. Spitzer's infrared vision detected a huge eruption around the star NGC 2547-ID8 between August 2012 and 2013. Scientists think the dust was kicked up by a massive collision between two large asteroids. They say the smashup took place in the star's “” terrestrial zone,””” the region around stars where rocky planets like Earth take shape.

Elliptical galaxy NGC 1275 in Persee - Elliptical galaxy NGC 1275 in Perseus - This image obtained by the Hubble space telescope in 1995 shows a system of two colliding galaxies; in the foreground, a spiral galaxy seen almost from the edge, with many stars forming in the background, a giant, very bright elliptical galaxy, special because it has a spiral structure in its center. Its core probably houses a black hole. NGC 1275 is located about 230 million years ago - light; it belongs to the large cluster of galaxies of Persee. These images, taken with Hubble's Wide Field Planetary Camera 2 (WFPC2), show traces of spiral structure accompanied by dramatic dust lanes and bright blue regions that mark areas of active star formation. Detailed observations of NGC 1275 indicate that the dusty material belongs to a spiral system seen nearly edge - on in the foreground. The second galaxy, lying beyond the first, is actually a giant elliptical with peculiar faint spiral structure in its nucleus.

A broad dark band crosses it in the middle, a probable vestige of a collision with a spiral galaxy. This giant galaxy is a powerful radio source known as Centaurus A. It is an active galaxy whose energy comes from a supermassive black hole. The green dot visible in the dust strip is a supernova, the supernova 1986g. It appears green because the red filter image that made this trichromy image was only taken a year after the event and the supernova had weakened. Image obtained from the 3.9m telescope of Siding Spring, Australia. The nearby radio source Centaurus A (NGC 5128) looks like an elliptical galaxy, crossed by a broad, irregular dust lane. The dark band is probably the remains of a dusty spiral galaxy which is being absorbed by the giant elliptical. One
