Open cluster of Pleiades - Open cluster of Pleiades - The north is at top. The Pleiades star cluster, also known as the Seven Sisters and Messier 45, is one of the brightest and famous star clusters visible in the northern hemisphere. It consists of about 500 bright, hot, young stars that were all born at the same time between 75 and 150 million years ago within a large cloud of dust and gas. The cluster contains many stars, of which only a handful are commonly visible to the naked eye. The blue haze that accompanies them is due to very fine dust which still remains and preferentially reflects the blue light from the stars. This star cluster lies some 440 light years away from the Earth, in the constellation of Taurus. This image is based on data acquired by the Oschin Telescope at the Mount Palomar Observatory

Cone Nebula NGC 2264 in the Unicorn - The Cone Nebula NGC 2264 in Monoceros - The Cone Nebula is a star-forming region situated about 2600 years away from Earth. It is accompanied by a cluster of stars called the Christmas tree. Image obtained with a 50 cm telescope, composite of several images. The Cone Nebula (also known as NGC 2264) is an H II region in the constellation of Monoceros. It was discovered by William Herschel in 1785. The nebula is located about 800 parsecs or 2,600 light - years away from Earth. The Cone Nebula is part of the nebulosity surrounding the Christmas Tree Cluster. The designation of NGC 2264 in the New General Catalogue refers to both objects and not the nebula alone

Open cluster Westerlund 1 in the Altar - Open cluster Westerlund 1 in Ara - The open cluster Westerlund 1 is located about 16,000 years - light in the southern constellation of the Altar. It contains hundreds of very young massive stars as well as the supergiant red star W26. Image obtained by the VST telescope in Chile. This exceptionally bright cluster lies about 16 000 light - years from Earth in the southern constellation of Ara (The Altar). It contains hundreds of very massive and brilliant stars, all of which are just a few million years old - - babies by stellar standards. But our view of this cluster is hampered by gas and dust that prevents most of the visible light from the cluster's stars from getting to Earth.

Open cluster Westerlund 1 in the Altar - Open cluster Westerlund 1 in Ara - The open cluster Westerlund 1 is located about 16,000 years - light in the southern constellation of the Altar. It contains hundreds of very young massive stars as well as the supergiant red star W26. Image obtained by the VST telescope in Chile. This exceptionally bright cluster lies about 16 000 light - years from Earth in the southern constellation of Ara (The Altar). It contains hundreds of very massive and brilliant stars, all of which are just a few million years old - - babies by stellar standards. But our view of this cluster is hampered by gas and dust that prevents most of the visible light from the cluster's stars from getting to Earth.

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.

Markarian Galaxy 273 - Galaxy Markarian 273 - The Markarian galaxy 273 is about 500 million light years away from Earth in the constellation of the Great Bear. The presence of a 130,000-year-long maree tail suggests that Markarian 273 is the fusion of two galaxies. The collision caused a burst of star formations. This galaxy has a double core and is one of the brightest infrared galaxies. Image obtained by the Hubble Space Telescope on November 16, 2001. Markarian 273 shows an intricate central region and a striking tail that extends diagonally towards the bottom - right of the image.

Nebula NGC 3603 in Carene - Star formation region NGC 3603 in Carina - NGC 3603 is located about 7000 years - light from Earth in the constellation Carene. Within this nebula, a cluster of massive stars, Wolf - Rayet stars. Image obtained by Siding Spring's 3.9m telescope. Although stars are well known to form in clusters, most of the stars in the young groups we know of in our own galaxy are well separated in space. In NGC 3603 the stars are remarkably close together. Moreover, many of the stars in this compact constellation are Wolf - Rayet stars, extremely hot, massive objects, rarely found in such profusion in clusters. Exactly why some clusters form massive stars and others do not is a hot topic in astronomy, so this cluster and its environment has been extensively studied. This curious collection of young objects is, as far as we know, unique in our galaxy, though the enigmatic object at the centre of the Tarantula Nebula in the Large Magellanic Cloud is now known to be a similar

This example is about 6000 - 7000 light years distant. Three - colour composite mosaic image based on images obtained with the Wide - Field Imager camera on the MPG/ESO 2.2 - metre telescope at the La Silla

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 mat

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 by Siding Spring's 3.9m telescope. In the hollowed - out centre of the Rosette nebula lies NGC 2244, the cluster of young stars recently formed there. The cluster has itself created the cavity, radiation pressure and stellar winds from the stars blowing the gas and dust away from the young cluster. The hottest (and brightest) members of the group are seen as distinctly blue on this photograph, a colour corresponding to a surface temperature around 20,000K which may be compared with the Sun's 5500K. The nebula and its cluster is at a distance of about 4500 light years and shows many streaks and globules of dust, remnants of the cloud from which the stars formed

S star Monocerotis and nebula - Fox Fur nebula in Monoceros - The region to the right of the bright star S Monocerotis is called Fox Fur nebula. This region where gas mixes with interstellar dust is located above the Cone nebula, about 2600 light years from Earth. Image obtained with a 61 cm telescope, composite of several images. The region around the 4.7 magnitude star S Mon is a fascinating mixture of red fluorescent hydrogen and dark, obscuring dust lanes. Some dust patches are close enough to bright stars to reflect light from them; these appear blue for the same reason that the day - time sky is blue - because some of the interstellar particles preferentially scatter blue light. The dust is mixed with gas and this affects the appearance of the emission nebulae, giving some of the faintest a curious 'fox fur' texture in this photograph. S Mon is part of a young open cluster of stars named NGC 2264 located about 2600 light years away, just north of the Cone nebula. Image taken with

Circumpolar and Shooting Star - Circumpolar and Meteor - Circumpolar and meteor - A shooting star passes near the polar eoile. Photographic pose of 60 minutes obtained in April 1995. By pointing a camera towards the north at night, we can record the paths of stars which never set. They appear to circle the apparent position of the Earth's axis of rotation projected on the sky. On this 1 hour exposure, a shooting star appears near the pole star

Open cluster NGC 6242 in Scorpio - Open star cluster NGC 6242 in Scorpius - This cluster is about 3500 years old - light from the Sun and is about 50 million years old. A bright yellow star is in the foreground. This cluster is one of many in the sparkling southern constellation of Scorpius. It is marked by a bright yellow star (spectral type K5) which happens to be in the foreground at a distance of about 1000 light years. The cluster itself is about 3,500 light years from the sun. The cluster is slightly dimmed by foreground dust. This so - called interstellar extinction is common with object close to the Galactic plane. Despite this, it is possible to estimate the age of the cluster by measuring the color and relative brightness of its stars. The age turns out to be about 50 million years, which is quite mature for an open cluster of this type. By now, most of the brightest stars will have turned into supernovae and vanished, leaving this quite modest group to compete with the many

These two star - formation regions appear side by side in the sky and seem to be linked as parts of an extensive nebula. However, the apparent intimacy is line - of - sight effect because these two objects are at quite different distances from the Sun. The curious looped nebula NGC 3576 is about 7000 light years from us while its neighbour NGC 3603 is more than twice as far away. That NGC 3603 is the more distant is confirmed by its colour, which is a ruddier red than the pinkish hue of NGC 3576. The change in colour is due to absorption of the blue - light component of the nebulosity by dust particles in the much longer line of sight. This effect is known as interstellar reddening, though it would be bette
