Dust in Iris Nebula - Dust in Iris Nebula - The Iris Nebula (NGC 7023) is a reflexion nebula illuminated by the star HD 200775. This image obtained by the Hubble Space Telescope shows a detail of the nebula or HD star 200775 (at the top of the image, out of the field) illuminates tiny particles of dust. This close - up of an area in the northwest region of the large Iris Nebula (NGC 7023) seems to be clogged with cosmic dust. With bright light from the nearby star HD 200775 illuminating it from above, the dust resemble thick mounds of billowing cotton. It is actually made up of tiny particles of solid matter, with sizes from ten to a hundred times smaller than those of the dust grains we find at home. Both background and foreground stars are dotted throughout the image. North is down, East is right. The field of view is 3.3 arcminutes. The image is a composite of four images obtained by the Hubble space Telescope through blue, green, near - infrared and H - alpha filters

Southern cross and Coal Sack nebula - The coal bag located near the Southern Cross is a molecular cloud of a high concentration of gas and dust that absorbs almost all the visible light emitted by the stars in the background. The Coal Sack is a large dark patch lying in very rich star field of the milky way. It is a dark nebula, an interstellar dust cloud obscuring the light of the stars behind it

Nebula NGC 7023 in Cephee - Iris Nebula in Cepheus - The nebula of the Iris (NGC 7023) is a reflexion nebula illuminated by the star HD 200775. Infrared observations indicate that this nebula contains PAH (aromatic polycyclic hydrocarbons), molecules composed of carbon atoms and hydrogen. NGC 7023 (The Iris Nebula) is located 1400 Light Years away. The bright star HD 200775 shining through the nebula NGC 7023 is a 10 solar mass star centrally imbedded in a region surrounded by ambient molecular cloud material. Infrared observations indicate that this nebula may contain complex carbon molecules known as PaHS

Nebuleuse Barnard 86 & open cluster NGC 6520 - Dark nebula Barnard 86 and open cluster NGC 6520 - NGC 6520, is a cluster of young stars aged a few million years. To its right is the dark nebula, Barnard 86, a cloud of molecular gas and dust, very cold, in which these stars have become formed. In the background, the billions of years old stars of Sagittarius. NGC 6520 is a small cluster of young blue stars. In the same region is a dark cloud, Barnard 86. The cluster and cloud are probably associated and the dust is visible only because it blocks out light from the myriads of stars beyond. On the distant background, old yellowish stars in Sagittarius are visible in vast numbers

These cold gas columns are home to star embryos. The NASA/ESA Hubble Space Telescope has revisited one of its most iconic and popular images: the Eagle Nebula's Pillars of Creation. This image shows the pillars as seen in visible light, capturing the multi - coloured glow of gas clouds, wispy tendrils of dark cosmic dust, and the rust - colored elephants trunks of the nebula's famous pillars. The dust and gas in the pillars is seared by the intense radiation from young stars and eroded by strong winds from massive nearby stars. With these new images comes better contrast and a clearer view for astronomers to study how the structure of the pillars is changing over time.

Cluster of stars NGC 299 in Toucan - Open cluster NGC 299 in Tucana: NGC 299 is an open cluster located in the galaxy of the Little Magellan Cloud. Image obtained by the Hubble Space Telescope (HST). NGC 299 is an open star cluster located within the Small Magellanic Cloud just under 200 000 light-years away. Open clusters such as this are collections of stars weakly bound by the shackles of gravity, all of which formed from the same massive molecular cloud of gas and dust. Because of this, all the stars have the same age and composition, but vary in their mass because they formed at different positions within the cloud. This unique property not only ensures a spectacular sight when viewed through a sophisticated instrument attached to a telescope such as Hubble's Advanced Camera for Surveys, but gives astronomers a cosmic laboratory in which to study the formation and evolution of stars - a process that is thought to depend strongly on a star's mass

Molecular cloud B 68 in Ophiuchus seen in infrared - False - colour composite based on a visible (here rendered as blue), a near - infrared (green) and an infrared (red) image. Since the light from stars behind the cloud is only visible at the longest (infrared) wavelengths, they appear red. At a distance of only 410 light - years, Barnard 68 is one of the nearest dark clouds. Its size is about 12,500 AU (= 2 million km; 1 Astronomical Unit [AU] = 150 million km), or just about the same as the so - called “” Oort Cloud””” of long - period comets that surrounds the solar system. The temperature of Barnard 68 is 16 Kelvin (- 257* C) The total mass of the cloud is about twice that of the Sun

Nebulae of the horse's head and M42 in Orion - Horsehead and Orion nebulae - Dark Nebula of the horse's head (IC434 - B33). Further down, the large Orion nebula (M42) vast star-forming region. These nebulae are located 1500 years of light from Earth. Image obtained from the 1.2m Schmidt telescope of Siding Spring. 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. In contrast, the wisps of the Horsehead Nebula are much fainter but even here faint tendrils of nebulosity show

An artist's animation of a protoplanetary disk, which will eventually turn into a solar system. In the center is a star. As the star grows, its gravitational pull draws in dust and gas from the surrounding molecular cloud to form a swirling disk called a "protoplanetary disk." This disk eventually further consolidates to form planets, moons, asteroids and comets.

Within this nebula a yellow cloud surrounds a T - Tauri star, a very young star in formation. The orange star in this view is T Tauri, prototype of the class of T Tauri variable stars. Nearby it is a dusty yellow cosmic cloud historically known as Hind's Variable Nebula (NGC 1555/1554). Over 400 light - years away, at the edge of a molecular cloud, both star and nebula are seen to vary significantly in brightness but not necessarily at the same time, adding to the mystery of the intriguing region. T Tauri stars are now generally recognized as young (less than a few million years old), sun - like stars still in the early stages of formation

Young stars in Rho Ophiuchi - Young stars in Rho Ophiuchi - Image of the central part of Rho Ophiuchi obtained in infrared by the Spitzer space telescope. Rho Ophiuchi is a vast dark cloud of molecular hydrogen located 407 years - light from Earth in the constellations of Ophiuchus and Scorpio. More than 300 young stars aged only 300,000 years have been observed. On this picture in false colors highlighting the temperature differences present in this cloud, the younger stars appear in red, the more evolute stars in blue. Newborn stars peek out from beneath their natal blanket of dust in this dynamic image of the Rho Ophiuchi dark cloud from Nasa's Spitzer Space Telescope. Called “” Rho Oph””” by astronomers, it's one of the closest star - forming regions to our own solar system. Located near the constellations Scorpius and Ophiuchus, the nebula is about 407 light years away from Earth. Rho Oph is a complex made up of a large main cloud of molecular hydrogen, a key molecule allowing new

Nebulae B175 and VDB 152 in Cephee - Dark nebula B175 and reflection nebula VDB 152 - Located about 1400 years ago - light in the constellation Cephee, a large dust trail leads to a bluish nebula. This is the dark nebula, Barnard 175, which faces the nebula by reflexion VDB 152 (Ced 201). The reflection nebula vdB 152 is really very faint. It lies about 1400 light - years away, along the northern Milky Way in the constellation Cepheus. Near the edge of a large molecular cloud, pockets of cosmic dust in the region block light from background stars or scatter light from the embedded bright star (top) giving parts of the nebula a characteristic blue color. Ultraviolet light from the star is also thought to cause a dim reddish luminescence in the nebular dust. Although stars do form in molecular clouds, this star seems to have only accidentally wandered into the area, as its measured velocity through interstellar space is very different from the cloud's velocity

Detail of the horse's head nebula by the VLT - Horsehead Nebula, which is situated in the Orion molecular cloud complex. Its official name is Barnard 33 and it is a dust protrusion in the southern region of the dense dust cloud Lynds 1630, on the edge of the HII region IC 434. The distance to the region is about 1400 light - years (430 pc). This beautiful colour image was produced from three images obtained with the multi - mode FORS2 instrument at the second VLT Unit Telescope (KUEYEN) on February 1, 2000. Three predominant colours are seen in the image: red from the hydrogen (H - alpha) emission from the HII region; brown for the foreground obscuring dust; and blue - green for scattered starlight. The blue - green regions of the Horsehead Nebula correspond to regions not shadowed from the light from the stars in the H II region to the top of the picture and scatter stellar radiation towards the observer; these are thus 'mountains' of dust

Dark Nebula in Scorpio - A dark cloud in Scorpius - Unnamed nebula in Scorpius. Bright rimmed globules and their more evolved cousin the cometary globule represent fascinating dynamic structures formed by the interplay of cold molecular clouds and hot ionizing stars. Typically the head of the globule faces a hot O - type star. Intense radiation from the star boils away lower density gas from the head. The evaporated rim of gas becomes ionized by the stars ultraviolet flux forming a bright glowing rim we associate with many of these globules including CG4. Intense stellar winds from the ionizing star evaporate gas and dust away from the head forming the “” tail”” and completing the cometary shape. The blood cells are known to be the birthplace of low mass stars. Stars form within the blood cells by the mechanism known as “” radiation driven implosion”. This process occurs when ultraviolet flux from a hot star compresses surviving clumps of cold molecular gas eventually causing collapse

Open cluster Trumpler 5 in Unicorn - Open cluster Trumpler 5 in Monoceros - Trumpler 5 is a cluster of stars aged 125 million years. Image obtained by Siding Spring's 3.9m telescope As they age, open clusters of stars begin to lose their identity. This is partly because the brighter members tend to self - destruct as supernovae, and, though the group members share a common motion through space, they are only loosely bound. Thus stars drift away from the cluster in a process that accelerates with time. However, some clusters are big enough to retain their identity much longer than usual, and Trumpler 5 is one such. Its age is estimated to be 125 million years, and it must have been a spectacular sight in its youth. It seems to be at the edge of the Monoceros molecular cloud, where star formation is continuing new generations of young clusters

Hubble's exquisite resolution allows astronomers to pinpoint 50 separate stars tightly packed in the nebula's core within a 10 light - year diameter - slightly more than twice the distance between earth and the nearest star to our sun. The closest pair of stars is only 1/3 of a light - year apart (0.3 arcseconds in the sky). This furious rate of mass loss from these super - hot stars is evident in the Hubble picture that reveals dramatic shapes sculpted in the nebula's wall of glowing gases by violent stellar winds and shock waves. A pair of bright stars in the center of the nebula is pouri

Star Formation in the DR21 Region - Star Formation in the DR21 Region - This star-forming 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. Image obtained by the Spitzer space telescope in 2003. 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 seen in our Milky Way galaxy. The never - before - seen star is 100,000 times as bright as th

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
