Birth of stars in the nebula NGC 3372 - Star formation in the Carina Nebula - Detail of the nebula of the Carene seen in visible light (top) and infrared (bottom) by the Hubble space telescope. The top image shows a column of gas and dust eroded by ultraviolet radiation emitted by young stars. Jets are also visible, showing the presence of a nascent star. In the infrared image, the dust clouds radiate little, the nascent star responsible for these jets appears. NGC 3372 is located about 7000 light years away from Earth. Images obtained in July 2009. The pictures demonstrate one example of the broad wavelength range of the new Wide Field Camera 3 (WFC3) aboard the Hubble telescope, extending from ultraviolet to visible to infrared light. Composed of gas and dust, the pillar resides in a tempestuous stellar nursery called the Carina Nebula, located 7500 light - years away in the southern constellation of Carina. The pair of images shows that astronomers are given a much more complete vie

Nebulae NGC 3603 and NGC 3576 in Carene - NGC 3576 and 3603 in Carina - NGC 3576 (right) is located about 7000 years - light from Earth; NGC 3603 (left) is twice as far away. These two nebulae are located in the constellation Carene. Image obtained by Siding Spring's 3.9m telescope. 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

Constellations of Reticulum and Dorado - Constellations of Reticulum and Dorado - Constellations of Reticulum and Bream (top) near the galaxy of the Great Magellan Cloud. Reticulum is another small and insignificant southern constellation introduced by Lacaille in the 1750s. It commemorates a reticle, the cross hairs in an eyepiece used for measuring star positions, from the Latin for 'net' (hence reticulation, network). It is best found by looking for the Large Magellanic Cloud in the adjoining constellation of Dorado. Dorado, the Goldfish or Swordfish (Xiphias), is a constellation introduced by Johann Bayer, best known for his 1603 star atlas Uranometria, which was the first to cover the entire sky. It is notable mainly for containing most of the Large Magellanic Cloud (LMC), the nearest galaxy to the Milky Way

It is notable mainly for containing most of the Large Magellanic Cloud (LMC), the nearest galaxy to the Milky Way

In the foreground are the distinctive shapes of the Warrumbungle mountains in outback New South Wales. The exposure, on 400 ISO transparency film, was begun at the end of astronomical twilight, when the sun has descended 18 degrees below the horizon. There was a crescent moon and cloud around the south - western horizon. The exposure continued for several hours after the moon had set, and breaks in the star trails reveal that cloud had come and gone during the night

This view includes the whole galaxy and the surrounding sky, and clearly shows the asymmetric spiral arms. The longer of the two arms has intense star formation, which is visible here as a pink glow: this is due to the radiation of young stars ionising the gas they form from. The asymmetric shape and star formation are both thought to be caused by tidal disruptions from a near - miss with another galaxy at some point in its history

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

Nebula NGC 3576 in Carene - Star formation region NGC 3576 in Carina - NGC 3576 is located about 7000 years - light from Earth in the constellation Carene. Image obtained by Siding Spring's 3.9m telescope. The stars that excite this unusual nebula, NGC 3576, are not visible on this photograph. They are hidden in the dusty cloud at the 'base' (south) of the huge loops of nebulosity. This is material that has been blown out by radiation pressure and stellar winds from the concealed stars. Silhouetted against the tenuous loops are dark clouds of dust with bright rims which indicate the direction of the stars which excite the nebula. This large complex of gas and dust is at about the same distance as the much brighter Eta Carinae nebula, about 7000 light years away

Open cluster NGC 4755 - Jewel box - The Jewel Box cluster - The NGC 4755 cluster is located in the constellation of the Southern Cross at a distance of 7800 years - light from Earth. The bright orange star is Kappa Crucis, a supergiant red star. This cluster contains about fifty stars formed about 14 million years ago. NGC4755 (Caldwell 94) is called the Jewel Box, based on John Herschel's comment in the 1830's that it looked like a superb piece of jewelry. There are about 50 stars in this cluster which formed some 14 million years ago. Most of the cluster members are blue giants which in a few million years will exhaust their hydrogen fuel and become red giants on their way to a cataclysmic end as supernovae. One red giant can already be seen at the center of the cluster

The identification of Lupus as a wolf seems to have been made in relatively recent times. Both Lupus and Norma are in the rich starfields of the southern Milky Way, easily seen between Antares and alpha and beta Centaurii. The brightest object in this image is Jupiter, on the ecliptic at the top of the frame. Norma, (originally Norma and Regula, the builder's level and set square) is an insignificant scattering of stars compared to Lupus and Centaurus.

This image was obtained by the Hubble Space Telescope in September 2004. NGC 1300 is considered to be prototypical of barred spiral galaxies. Barred spirals differ from normal spiral galaxies in that the arms of the galaxy do not spiral all the way into the center, but are connected to the two ends of a straight bar of stars containing the nucleus at its center. At Hubble's resolution, a myriad of fine details, some of which have never before been seen, is seen throughout the galaxy's arms, disk, bulge, and nucleus. Blue and red supergiant stars, star clusters, and star - forming regions are well resolved across the spiral arms, and dust lanes trace out fine structures in the disk and bar. Numerous more distant galaxies are visible in the background, and are seen even through the densest regio

Interacting galaxies NGC 1614 - Interacting galaxies NGC 1614 - The galaxy NGC 1614 is located about 200 million light years away from Earth in the southern constellation of Eridan. This system is composed of interacting galaxies. Image obtained by the Hubble Space Telescope on August 13, 2002. The galaxy system NGC 1614 has a bright optical center and two clear inner spiral arms that are fairly symmetrical. It also has a spectacular outer structure that consists principally of a large one - sided curved extension of one of these arms to the lower right, and a long, almost straight tail that emerges from the nucleus and crosses the extended arm to the upper right. The galaxy appears to be the result of a tidal interaction and the resulting merger of two predecessor systems. The system has a nuclear region of quasar - like luminosity, but shows no direct evidence for an active nucleus. It is heavily and unevenly reddened across its nucleus, while infrared imaging also shows a ridge of d

Planetary nebula ESO 166 - 21 dans les Voiles - The faint planetary nebula ESO 166 - 21 - This planetary nebula was discovered in the rich southern constellation of Vela in 1966, which is why it does not have an NGC number. The 'Ack' designation refers to its identification in the catalogue of planetary nebulae edited by Agnes Acker. This beautifully structured delicate sphere of glowing gas is about 2 arc minutes in diameter and is extremely faint. Both these characteristics have contributed to the conspicuous grain 'noise' in the photograph, and attempts to emphasise the faint nebulosity also bring out the many faint stars in this direction, including the markedly blue central star of visual magnitude 18 which is seen here sandwiched between two other, brighter stars

Cometary Globula CG30 in the Stern - Cometary Globule CG30 - Cometary cells are small clouds of isolated gases. These, called CG30/31/38, are located about 1300 light years ago in the constellation Pupus. The Cometary Globules CG 30/31/38 are located 1300 light years away in Vela/Puppis constellations; they appear as finger - like extensions extending out in different directions. 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. The blood cells are known to be the birthplace of low mass stars. The globule head of CG 30 contains the Herbig Haro object HH 120, which is the outflow signature of a pre - main sequence star
