Star T - Tauri in Orion - Bow Shock around T - Tauri Star in the Orion Nebula - LL Ori is a star T - Tauri located about 1500 years ago - light from Earth in Orion's nebula. This young star emits a powerful stellar wind that hits the surrounding gas creating an arc-shaped shock wave Image obtained by the Hubble space telescope in February 1995. A bow shock can be created in space when two streams of gas collide. The star LL Ori emits a vigorous solar wind, a stream of charged particles moving rapidly outward from the star. Our own Sun has a less energetic version of this wind that is responsible for auroral displays on the Earth. The material in the fast wind from LL Ori collides with slow - moving gas evaporating away from the center of the Orion Nebula, which is located to the lower right in this Heritage image. The surface where the two winds collide is the crescent - shaped bow shock seen in the image. Unlike a water wave made by a ship, this interstellar bow shock is a three - dimensional structure. The filamentary emission has a very distinct boundary on the side facing away from LL Ori, but is diffuse on the side closest to the star, a characteristic common to many bow shocks. A second, fainter bow shock can be seen around a star near the upper right - hand corner of the image. Astronomers have identified numerous shock fronts in this complex star - forming region and are using this data to understand the many complex phenomena associated with the birth of stars. This image was taken in February 1995 as part of the Hubble Orion Nebula mosaic. A close visitor in our Milky Way galaxy, the nebula is only 1,500 light - years from Earth. The filters used in this color composite represent oxygen, nitrogen, and hydrogen emissions — Star T - Tauri in Orion - Bow Shock around T - Tauri Star in the Orion Nebula - LL Ori is a star T - Tauri located about 1500 years ago - light from Earth in Orion's nebula.

Central region of the elliptical galaxy Centaurus A (NGC 5128) - Central part of the galaxy Centaurus A (NGC 5128) - The galaxy NGC 5128 is located about 13 million years away from Earth in the southern constellation of Centaurus. 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 of the nearer galaxies, 13 million light years away, Centaurus A is the most powerful nearby radio source and is also a copious source of X - and gamma rays as well as visible and infrared radiation.The three plates which were combined to make this colour picture have been copied to enhance the fine detail of the dust lane and to suppress the bright background of the elliptical galaxy. This process reveals many tiny red star - forming regions, especially prominent towards the end of the dust lane, and the clumps of young blue stars recently formed from them. The curious green star in the dust lane is because the blue and green - light plates were taken when supernova 1986g had just appeared, while the red - light plate was taken a year later when the supernova had faded — Central region of the elliptical galaxy Centaurus A (NGC 5128) - Central part of the galaxy Centaurus A (NGC 5128) - The galaxy NGC 5128 is located about 13 million years away from Earth in the southern constellation of Centaurus.

Several generations of stars appear on this cliche; the older ones are the blue stars in the centre of the two cavities; the younger stars are grouped at the edges of these cavities and at the ends of the gas pillars or they appear like pink dots; the white areas are home to the very young stars in formation. In this infrared image, heated dust appears in red, dense gas clouds appear in green. Composite image obtained by the Spitzer space telescope in 2006 and 2007. Generations of stars can be seen in this infrared portrait from Nasa's Spitzer Space Telescope. In this wispy star - forming region, called W5, the oldest stars can be seen as blue dots in the centers of the two hollow cavities (other blue dots are background and foreground stars not associated with the region). Younger stars line the rims of the cavities, and some can be seen as pink dots at the tips of the elephant - trunk - like pillars. The white knotty areas are where the youngest stars are forming. Red shows heated dust that pervades the region's cavities, while green highlights dense clouds. W5 spans an area of sky equivalent to four full moons and is about 6,500 light - years away in the constellation Cassiopeia. The Spitzer picture was taken over a period of 24 hours. Like other massive star - forming regions, such as Orion and Carina, W5 contains large cavities that were carved out by radiation and winds from the region's most massive stars. According to the theory of triggered star - formation, the carving out of these cavities pushes gas together, causing it to ignite into successive generations of new stars.

This image obtained by a 50 cm amateur telescope, in February 2010 for 23 hours of poses, shows gas filaments whose origin is uncertain. Located about 12 million light - years from our planet, M81 (NGC 3031) together with M82 (NGC 3034), NGC 3077 and NGC 2976 forms one of the most iconic groups of interacting galaxies. The M81 group has also been the subject of many studies searching for and analyzing evidence of strong interactions among its components. In 1965, Halton Arp detected an unusual looping feature near M81 while examining photographic plates produced with the 48 - inch Schmidt on Mount Palomar. Traditionally, ARP's loop has been interpreted as a tail resulting from the tidal interaction between M81 and M82. However, since its discovery that explanation has been doubted by many researchers. Interestingly, the region of the sky containing the M81 group of galaxies is filled with Galactic cirrus and ARP's loop exhibits colors and emission properties similar to those observed in Galactic cirrus clouds. This optical image suggests that the light observed at optical wavelengths is a combination of emissions from: recent star forming regions situated near M81, the extended disk of M81 and scattered light from the same Galactic cirrus that is responsible for the bulk of the far infrared emissions. Although our observations cannot exclude the presence of some material stripped from the disk of M81 (NGC 3031) and/or M82 (NGC 3034) that is chance located in our line of sight to and far behind this intruiging structure, our findings suggest that ARP's Loop is situated between the observer and M81 ( — Spiral galaxy M81 in the Great Bear - Spiral galaxy M81 in Ursa Major - The spiral galaxy M81 is located 12 million years ago - light from Earth.

Star Birth in Scorpio - Stellar nursery in Scorpius - RCW 120 is a star-forming region about 4200 years from Earth in the constellation Scorpio. In the center a hot and massive star emits powerful ultraviolet radiation, which ionize the surrounding gas, tearing off electrons from the hydrogen atoms and producing the characteristic red glow of H - alpha emissions. As this ionized region extends into space, the associated shock wave meets the surrounding cold interstellar gas and cosmic dust. This gas becomes unstable and collapses under its own gravite forming dense, cold clouds or new stars will be born. These very cold clouds (- 250 degres Celsius) can only be detected in submillimetre wavelength; they appear here in blue thanks to the data obtained by the APEX telescope which observes this radiation. Illustrating the power of submillimetre - wavelength astronomy, an APEX image reveals how an expanding bubble of ionised gas about ten light - years across is causing the surrounding material to collapse into dense clumps that are the birthplaces of new stars. The region, called RCW120, is about 4200 light years from Earth, towards the constellation of Scorpius.

Barree spiral galaxy NGC 2146 in the Giraffe - Barred spiral galaxy NGC 2146 in Camelopardalis - NGC 2146 is a barree spiral galaxy located about 70 million years ago - light from Earth in the constellation Giraffe (Camelopardalis). Image obtained by the Hubble Space Telescope (HST). NGC 2146 is classified as a barred spiral due to its shape, but the most distinctive feature is the dusty spiral arm that has looped in front of the galaxy's core as seen from our perspective. The forces required to pull this structure out of its natural shape and twist it up to 45 degrees are colossal. The most likely explanation is that a neighbouring galaxy is gravitationally perturbing it and distorting the orbits of many of NGC 2146's stars. It is probable that we are currently witnessing the end stages of a process which has been occurring for tens of millions of years. NCG 2146 is undergoing intense bouts of star formation, to such an extent that it is referred to as a starburst galaxy. This is a common state for barred spirals, but the extra gravitational disruption that NGC 2146 is enduring no doubt exacerbates the situation, compressing hydrogen - rich nebulae and triggering stellar birth. Measuring about 80 000 light - years from end to end, NGC 2146 is slightly smaller than the Milky Way. It lies approximately 70 million light - years distant in the faint northern constellation of Camelopardalis (The Giraffe). Although it is fairly easy to see with a moderate - sized telescope as a faint elongated blur of light it was not spotted until 1876 when the German astronomer Friedrich Winnecke found it visually using just a 16 cm telescope. This picture was created from images taken with the Wide Field Channel of Hubble's Advanced Camera for Surveys. Images through a near - infrared filter (F814W, coloured blue and orange/brown) were combined with images taken in a filter that isolates the glow from hydrogen gas (F658N, coloured red).

The nebulous galaxy features a bright central bulge and diffuse arms with distinct star - forming regions. In the background, many other distant galaxies can be seen. The constellation Dorado is home to the Dorado Group of galaxies, a loose group comprising an estimated 70 galaxies and located some 62 million light - years away. The Dorado group is much larger than the Local Group that includes the Milky Way (and which contains around 30 galaxies) and approaches the size of a galaxy cluster. Galaxy clusters are the largest groupings of galaxies (and indeed the largest structures of any type) in the Universe to be held together by their gravity. Barred spiral galaxies are so named because of the prominent bar - shaped structures found in their center. They form about two thirds of all spiral galaxies, including the Milky Way. Recent studies suggest that bars may be a common stage in the formation of spiral galaxies, and may indicate that a galaxy has reached full maturity.

Barree spiral galaxy NGC 2442 in Flying Fish - NGC 2442, a barred spiral galaxy in Volans - NGC 2442 is a barree spiral galaxy located about 50 million years ago - light. Its asymmetrical shape suggests that a galaxy interacts with it. Image made with Siding Spring's 3.9m telescope. This unusual barred spiral galaxy is in the far southern constellation of Volans and was discovered by Sir John Herschel who described one of its spiral arms as hook - like. Although not seen here, (but evident on very deep images) NGC 2442 appears to have a less massive, distant companion that is also distorted, and it seems likely that the two have had a close encounter in the recent past. If there are no further meetings, the forces that hold NGC 2442 together will restore galaxy to a more symmetrical spiral form. However, much more likely is that the companion has been captured by the distorted spiral and will eventually be devoured by it, triggering a dramatic bout of star formation.

Orion's Nebula - The Great Nebula in Orion - Located 1500 light years from Earth, Orion's Nebula is the closest region to the formation of stars of the Sun. In its heart, a group of young stars called Orion's Trapeze. To the eye, the nebula appears as a misty patch around the central star of the line of three which form Orion's sword. The central group of stars is the Trapezium cluster and 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

Dark Nebula in Scorpio - A dark cloud in Scorpius - This dark nebula is located about 5000 years from Earth. Image obtained by Siding Spring's 3.9m telescope. This curious un - named nebula is governed by radiation from very luminous stars some distance from the nebula. The direction of the radiation source can be seen from the flow pattern in the dark cloud and the extensive bright red rims at the end of the nebula that is exposed to radiation from the hot stars. This part of the nebula is reminiscent of the famous Horsehead nebula in Orion, which is also the consequence of starlight destroying a dark cloud.

This system consists of two colliding galaxies each with a central black hole; in several millions of years, they will form only one galaxy. A composite X-ray image (red, orange and yellow) and visible from the space telescopes Chandra and Hubble. This image of NGC 6240 contains X - ray data from Chandra (shown in red, orange, and yellow) that has been combined with an optical image from the Hubble Space Telescope. In 2002, the discovery of two merging black holes was announced based on Chandra data in this galaxy. The two black holes are a mere 3,000 light years apart and are seen as the bright point - like sources in the middle of the image. Scientists think these black holes are in such close proximity because they are in the midst of spiraling toward each other - a process that began about 30 million years ago. It is estimated that the two black holes will eventually drift together and merge into a larger black hole some tens or hundreds of millions of years from now.

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. This nebula is quite nearby (5500 light years) but located close to the Galactic plane and are buried in the dust of the Milky Way. Careful measurement of the colour of stars associated with the nebula indicate that they are dimmed by a factor of about 10 in the green part of the spectrum, much more in the blue, but relatively little at red wavelengths.

Spiral galaxy NGC 1313 in the Reticule - The starburst galaxy NGC 1313 - NGC 1313 is a galaxy located about 15 million years ago - light. Intense star formations are observed. Image made with Siding Spring's 3.9m telescope. In visible light, NGC 1313 seems dominated by scattered patches of star formation which give our picture a rather ragged appearance. The clouds of bluish stars seem to have burst into existence at random, without the normal trigger gravitational interaction or even a distinct spiral to prompt them. Star formation seems to have occurred in a series of irregular, self-sustaining bursts. However, a very deep image shows that the outer parts of galaxy are also very disturbed. Seen with a radio telescope, the galaxy is rich in hydrogen, the raw material of stars, and the gas circulates around the centre of the galaxy in a well ordered way, apparently hardly affected by the starburst activity or other irregularities that so colour our visual impression of this unusual galaxy. NGC 1313 is at a distance of about 15 million light years, close enough for some of its brightest stars to be seen as individuals — Spiral galaxy NGC 1313 in the Reticule - The starburst galaxy NGC 1313 - NGC 1313 is a galaxy located about 15 million years ago - light.
