Nebula N70 in the Great Magellan Cloud - The N 70 nebula in Large Magellanic Cloud (LMC) - The Henize 70 nebula extends for about 400 years - light, it is located in the Great Magellan Cloud. In the center, a small group of very massive and extremely hot stars, stars of Wolf - Rayet. Image obtained by Siding Spring's 3.9m telescope. At the centre of this remarkable bubble - like nebula nebula is a small group of extremely hot stars. Some of these stars are rapdly losing mass and have stellar winds blowing from their surfaces with velocities that approach 4000 kilometers per second. Such stars are known as Wolf - Rayet stars and are found in galaxies capable of forming massive stars. There are many such stars in the Large Magellanic Cloud (LMC) but not all of them are associated with distinctive nebulae. The outward flowing streams of energetic particles from Wolf - Rayet (and other energetic stars) eventually interact with the relatively stationary interstellar medium pervading the LMC

Nebula N90 in the Little Magellan Cloud - N90 nebula in the Small Magellanic Cloud - View of nebula N90 in the Little Magellan Cloud, a galaxy next to our located 200 000 years - light from Earth. At the heart of this star-forming region is the cluster of stars NGC 602. These young stars have emerge from their cocoon of gas blowing the surrounding matter; the gas pillars pointing towards these stars are a sign of this erosion. In the dark clouds, other stars are forming. In the background, many galaxies are visible. Composite images obtained by the Hubble Space Telescope in July 2004. N90 is one of the star - forming regions in the Small Magellanic Cloud approximately 200,000 light - years away from the Earth.. The rich populations of infant stars found here enable astronomers to examine star forming processes in an environment that is very different from that in our own Milky Way.

Nebula IRAS 05437+2502 - Nebula IRAS 05437+2502 - Nebula IRAS 05437+2502 is located in the constellation Taurus. Image obtained by the Hubble Space Telescope (HST). The little - known nebula IRAS 05437+2502 billows out among the bright stars and dark dust clouds that surround it in this striking image from the Hubble Space Telescope. It is located in the constellation of Taurus (the Bull), close to the central plane of our Milky Way galaxy. It appears to be a small, rather isolated, region of star formation and one might assume that the effects of fierce ultraviolet radiation from bright young stars probably were the cause of the eye - catching shapes of the gas. However, the bright boomerang - shaped feature may tell a more dramatic tale. The interaction of a high velocity young star and the cloud of gas and dust may have created this unusually sharp - edged bright arc. Such a reckless star would have been ejected from the distant young cluster where it was born and would travel at 20

Galaxy M82 in the Great Bear seen in X-rays - The galaxy M82 seen in X-ray - Image obtained by Chandra in X-rays, reveals a cloud (in red) of very hot gas of several million degres emitted from the central regions of the galaxy. M82 is an irregular galaxy distant about 12 million years - light from Earth. Its nucleus, which appears to have suffered from the passage of the neighbouring galaxy M81, is in a phase of violent star activity. Its central regions are rich in star formation. These hot stars blow a stellar wind that becomes a very violent galactic wind. Chandra's X - ray image reveals gas that has been heated to millions of degrees by the violent outflow of matter blasting out of the galaxy. The eruption can be traced back to the central regions of the galaxy where stars are forming at a furious rate, some 10 times faster than in the Milky Way Galaxy. Many of these newly formed stars are very massive and race through their evolution to explode as supernovas. Vigorous mass loss f

Irregular galaxy NGC 6822 in Sagittarius - Irregular galaxy NGC 6822 in Sagittarius - The galaxy NGC 6822 is about 1.6 million years away - light from Earth. She belongs to our local group. Image obtained with a telescope of 35 cm, 12 hours of poses. The irregular dwarf galaxy NGC 6822 is located at only 1,6 million light year. It is a member of our local group and the third nearest galaxy to the Milky Way after the Sagittarius Dwarf Elliptical and the Magellanic Clouds. The galaxy was discovered by Barnard in 1881 using a 6 inch refractor. It is very similar to the LMC with its weak bar and its irregular distribution of bright OB associations and HII regions. In 1925 in a classic paper, Edwin Hubble reported on several bright objects in NGC 6822, later found to represent a grouping of bright star clusters and HII regions. The galaxy is rich in neutral hydrogen gas, the essential fuel of star formation. NGC 6822 started forming stars some 10 billion years ago. Similar to the LMC it has

The field shown in this picture covers a relatively small patch of sky, a fraction of the area of the full moon, yet it is richly populated with a variety of galaxy types. A handful of large fully formed galaxies are scattered throughout the image. These galaxies are easy to see because they are relatively close to us.

Their pulse period is measured and their absolute luminosite is calculated. By comparing the result to their apparent luminosite in the sky, they can be calculated accurately. Here, the space telescope identified cepheides in the M81 galaxy; astronomers were able to deduce a new distance for this galaxy; it would be 11 million years - light from Earth; previous estimates gave a figure of 18 million light years. Image obtained in 1993. Astronomers have discovered variable stars in the spiral galaxy M81, and measured the distance of the galaxy to be 11 million light - years (3.4 megaparsecs).

Globular cluster 47 Toucan - The globular cluster 47 Tucanae, NGC 104 - The globular cluster 47 Toucan (or NGC 104) is visible to the naked eye from the southern hemisphere. Located about 15000 years ago - light it contains several million stars, some of which are among the older stars known today. At the top right of the image, part of the galaxy of the Little Magellan Cloud; under NGC 104, a small globular cluster, NGC 121. Discovered by Abbe Nicholas Louis de Lacaille on September 14, 1751. NGC 104, better known as 47 Tucanae, is the second largest and second brightest globular cluster in the skies, outshone only by another southern globular, Omega Centauri (NGC 5139). As its name “” 47 Tucanae”” indicates, this object was first cataloged as a star and numbered the 47th in Tucana. Although a conspicuous naked - eye object, it is situated so much south at its declination of - 72 deg, that it was not discovered as a deepsky object before 1751, when Abbe Lacaille cataloged it in his li

Nebuleuse N44 in the Great Magellan Cloud - This photo shows the southern part of the spectacular N44 region in the Large Magellanic Cloud. The green colour indicates areas that are particularly hot. The field measures 27.5 x 26.5 arcmin2., North is up and East is left. The two best known satellite galaxies of the Milky Way, the Magellanic Clouds, are located in the southern sky at a distance of about 170,000 light - years. They host many giant nebular complexes with very hot and luminous stars whose intense ultraviolet radiation causes the surrounding interstellar gas to glow. The intricate and colourful nebulae are produced by ionised gas that shines as electrons and positively charged atomic nuclei recombine, emitting a cascade of photons at well defined wavelengths. Such nebulae are called “” H II regions””, signifying ionised hydrogen, i.e. hydrogen atoms that have lost one electron (protons). Their spectra are characterized by emission lines whose relative intensities carry usefu

Nebula N81 in the Small Magellan Cloud - Celestial Maternity Ward N81 in the Small Magellanic Cloud A NASA Hubble Space Telescope “” family portrait””” of young, ultra - bright stars nested in their embryonic cloud of glowing gases. The celestial maternity ward, called N81, is located 200,000 light - years away in the Small Magellanic Cloud (SMC), a small irregular satellite galaxy of our Milky Way. 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

Eagle Nebula (IC 4703) in the Snake - detail - Young stars in the Eagle nebula - Detail on young stars located in the north - west part of the Eagle Nebula (M16). Image obtained by the Hubble Space Telescope. This picture shows the northwestern part of the Eagle nebula (M16), well away from the centre, and features some very bright young stars that formed from the same cloud of material. These energetic toddlers are part of an open cluster and emit ultraviolet radiation that causes the surrounding nebula to glow. The star cluster is very bright and was discovered in the mid - eighteenth century. The nebula, however, is much more elusive and it took almost a further two decades for it to be first noted by Charles Messier in 1764. Although it is commonly known as the Eagle Nebula, its official designation is Messier 16 and the cluster is also named NGC 6611. One spectacular area of the nebula (outside the field of view) has been nicknamed The Pillars of Creation”” ever since the Hubble S
