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 gal

WWII - North African Campaign 1942 : The image from the Nazi Propaganda! depicts camouflaged tents of the German Wehrmacht in Africa, published on 29 January 1942. Place unknown. The text on the back of the image reads: ""Tents in Africa. On the flat terrain of the desert, the soldiers can often only shield themselves from enemy view through special camouflaging. But also this camouflaging is at times linked to great difficulties because there are not many trees or bushes available. Here, the soldiers have brought brushwood to cover their tents on the open terrain so that they cannot be seen in the bird's eye perspective. - On the top: camouflage works on the tent, in which they live in. - Below: The camouflaged tent that can barely be recognized even at a small distance.""

Planetary nebula NGC 2899 dans les Voiles - A distorted planetary nebula, NGC 2899 - This nebula is located about 3000 years from Earth. Image obtained by the 3.9m telescope of Siding Spring Planetary nebulae present a wide variety of forms on the sky, partly because of the random orientation of their parent stars but also because the nebulae themselves can have quite different intrinsic shapes. Theories about the shapes of planetaries range from the influence of binary companions to the central star to the distribution of material around the stars during its red giant phase, before the final outburst. Whatever the mechanism, most planetaries are symmetrical about one or more axes and only rarely do they appear curved like NGC 2899.

Planetary nebula NGC 2899 dans les Voiles - A distorted planetary nebula, NGC 2899 - This nebula is located about 3000 years from Earth. Image obtained by the 3.9m telescope of Siding Spring Planetary nebulae present a wide variety of forms on the sky, partly because of the random orientation of their parent stars but also because the nebulae themselves can have quite different intrinsic shapes. Theories about the shapes of planetaries range from the influence of binary companions to the central star to the distribution of material around the stars during its red giant phase, before the final outburst. Whatever the mechanism, most planetaries are symmetrical about one or more axes and only rarely do they appear curved like NGC 2899. A possible explanation is that the star from which the nebula was ejected had a large proper motion through space. The resulting nebula has the same velocity but vastly lower density than the star so is distorted by its encounter with the tenuous interstell

Star cluster M46 and planetary nebula NGC 2438 - Open cluster M46 and planetary nebula NGC 2438 - M46 (NGC 2437) is an age cluster located at 5400 years - light. It contains about 500 stars, 150 of which are brilliant. It is about 300 million years old. The planetary nebula NGC 2438 does not appear to belong to this cluster, and must be closer although its distance is unknown. Image obtained by Siding Spring's 3.9m telescope The open cluster NGC 2437 (M46) has an angular diameter of almost half a degree and is quite beautiful in even quite a modest telescope. It has an integrated magnitude of about 6 and so is on the threshold of naked - eye visibility. The cluster is quite old as these things go, about 300 million light years. It is about 5000 light years distant, in the northern part of the constellation of Puppis. Although planetary nebula distances are notoriously difficult to measure, NGC 2438 seems to be in the foreground and is not connected to the cluster. Planetaries are in an

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

Image obtained by the 3.9m telescope of Siding Spring In March, 1871 Charles Messier noted as number 93 in his famous catalogue this conspicuous group as a cluster of small stars. It was one of the last objects that Messier himself listed though he lived until 1817. The cluster is in the southern constellation of Puppis (known to Messier as Argo Puppis) and is in a rich part of the Milky Way, almost on the Galactic equator. The group is quite compact and is on the threshold of naked - eye visibility under good conditions. It is at a distance of over 3000 light years.

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.

Mosaic of images obtained with a telescope of 35 cm, 22 hours of poses. This rich nebula complex is located near the center of the galaxy where dust is ubiquitous and often partially obscures the view at visible wavelengths. The two bright blue clouds are NGC 6589 and NGC 6590. The clouds represent scattered starlight from two imbedded young blue stars. The two bright stars are part of a loose cluster known as NGC 6595. The diffuse magenta cloud is a complex HII region which absorbs the energy from the nearby bright stars and releases it in the visible red light of excited hydrogen. The HII clouds are known as IC 1283, IC 1284 and IC 4700. This region of our galaxy is rich with dust clouds and young stars which together produce the stunning reflection nebulae we see in the image. Mosaic of images

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.

Mosaic of 14 images, 70 hours of cumulative poses. Known as the Tarantula Nebula for its spidery appearance, the 30 Doradus complex is a huge stellar factory. It is the largest emission nebula in the sky, and can be seen far down in the southern sky at a distance of about 170,000 light - years, in the southern constellation Dorado. It is part of one of the Milky Way's neighbouring galaxies, the Large Magellanic Cloud. The Tarantula Nebula is thought to contain more than half a million times the mass of the Sun in gas and this vast, blazing labyrinth hosts some of the most massive stars known. Su

Spiral Galaxy NGC 1566 in the Dorado - The Seyfert Galaxy NGC 1566 - NGC 1566 is a spiral galaxy located about 50 million years ago - light. Its core is very bright. It is an active galaxy called Seyfert, which probably houses a black hole in its heart. Image made with Siding Spring's 3.9m telescope. NGC 1566 is the brightest member of a nearby group of galaxies in Dorado and is at a distance of about 50 million light years. It has beautifully symmetrical, tightly - wound spiral arms, which on deep images appear to almost encircle the galaxy. This striking galaxy is also of interest because it has a very luminous nucleus which has many of the characteristics of a quasar, though it is much less energetic. Galaxies of this type are known as Seyfert galaxies, after Carl Seyfert who first recognised their peculiar nature in 1943. The active region at the centre of NGC 1566 has recently been found to vary on a timescale of less than a month, which indicates that it is extremely compact. Spe

In the plane of the rings of the planet appear from left to right the satellites Enceladus, Dione, Tethys and Rhea. Saturn and its rings would be a majestic sight lording over Titan's hydrocarbon haze. The viewpoint is from 50 miles above Titan's surface and three - quarters of a million miles away from Saturn itself. Four of Saturn's smaller satellites can also be seen along the ring plane: left to right are Enceladus, Dione, Tethys and Rhea. Technically, the orange clouds mark the beginning of Titan's condensate haze, which consists of ethane, methane, nitrogen, and a variety of hydrocarbons known collectively as tholin. These gases and hydrocarbons extend upward another 250 miles, resulting in a bluish, earthlike sky, albeit darker due to Titan's great distance from the Sun. Tholin is created by the inte

The Large Magellanic Cloud - The Large Magellanic Cloud - The Great Magellan Cloud galaxy is located about 160,000 light years away from Earth in the southern constellation of Dorado. Visible with the naked eye in the southern hemishere it is one of the closest galaxies to us. It contains large star-forming zones such as the Tarantula Nebula (30 Sea bream, visible to the left), the most active star-forming regions of the local group. Image obtained by the 1.2m UK Schmidt telescope from Siding Spring, Australia. The Large Magellanic Cloud (LMC) is the nearest galaxy to the Milky Way but less than one tenth as massive; even so it contains the equivalent of over ten billion solar masses of material in the form of stars, gas and dust. The LMC is at a distance of 160,000 light years and is visible to the unaided eye from southern latitudes, rather like a detached piece of the Milky Way. The nearness of the LMC ensures that it is well resolved into stars in quite a modest telescope, and deep

NGC 7424 extends over nearly 100,000 light years, like our galaxy. Numerous bright blue clusters of massive young stars are visible along the spiral arms. Image obtained by the telescope MELIPAL of the VLT on October 9, 2004 Composite colour - coded image of spiral galaxy, NGC 7424, at a distance of 40 million light - years. This galaxy is classified as “” SAB (rs) cd””, meaning that it is intermediate between normal spirals (SA) and strongly barred galaxies (SB) and that it has rather open arms with a small central region. It also shows many ionised regions as well as clusters of young and massive stars. Ten young massive star clusters can be identified whose size span the range from 1 to 200 light - years. The galaxy itself is roughly 100,000 light - years across, that is, quite similar in size to our own Milky Way galaxy. Images obtaine

Beginning in 2002, this star illuminated temporarily becoming one of the brightest stars in the sky. Viewed here in November 2005 by the Hubble space telescope, the light echo reveals details in the interstellar dust surrounding the star. Light from a star that erupted almost five years ago continues propagating outward through a cloud of dust surrounding the star. The light reflects or “” echoes”” off the dust and then travels to Earth. Because of the extra distance the scattered light travels, it reaches the Earth long after the light from the stellar outburst itself. Therefore, a light echo is an analog of a sound echo produced, for example, when sound from an Alpine yodeler echoes off of the surrounding mountainsides.

Image made with the 1.5m Danish telescope of La Silla in Chile. At the heart of the Lagoon Nebula in Sagittarius lies the diminutive Hourglass Nebula. Its gases are excited primarily by two massive O-type supergiants designated Herschel 36 and 9 Sagittarii. These two stars lie to the west of NGC 6530 and are separated from it by a dark lane which divides the nebula like a black lagoon, giving it its name. Twisted funnel shaped clouds are visible close to the illuminating stars, especially Herschel 36. The twists are due to shear forces between the hot excited gases at the surface and the cold interior of the clouds. These stars are probably less than 10,000 years o

Jupiter is in his last quarter phase. In the distance, a volcano erupts and the gases emitted into the thin atmosphere of Io illuminate in the magnetic field surrounding Jupiter and Io - Io keeps the same face towards Jupiter as it orbits the planet. For this reason, Jupiter appears to hang motionless in Io's sky. Just as the Earth's Moon does, Jupiter goes through phases as Io orbits it.
