PIX4609776: 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 galaxy. NGC 1313 is at a distance of about 15 million light years, close enough for some of its brightest stars to be seen as individuals / Bridgeman Images

PIX4609803: Elliptical galaxy NGC 1316 in the Furnace - Giant elliptical galaxy NGC 1316 - By studying the clusters of stars and clouds of dust visible in this photo taken by the Hubble space telescope in March 2003, it is believed that the giant elliptical galaxy NGC 1316 is the result of a collision of two spiral galaxies that occurred some billions of years ago. This galaxy resides about 75 million light years ago in the cluster of galaxies of the Furnace. Also called Fornax A, it is one of the strongest radio sources in the sky. This image made from data obtained with the NASA Hubble Space Telescope reveals the dust lanes and star clusters of this giant galaxy that give evidence that it was formed from a past merger of two gas - rich galaxies. NGC 1316 is on the outskirts of a nearby cluster of galaxies in the southern constellation of Fornax, at a distance of about 75 million light - years. It is one of the brightest ellipticals in the Fornax galaxy cluster. NGC 1316, also known as Fornax A, is one of the strongest and largest radio sources in the sky, with radio lobes extending over several degrees of sky (well off the Hubble image) / Bridgeman Images

PIX4609074: Stars in the spiral galaxy NGC 253 - Stars in galaxy NGC 253 - NGC 253 is the brightest galaxy of the Sculptor's group, group of galaxies closest to the Local Group. It is about 13 million light years away. Here, the Hubble space telescope photographed the different star populations of this galaxy. A close - up view from Hubble space telescope shows that NGC 253 is ablaze with the light from thousands of young, blue stars. The spiral galaxy is undergoing intense star training. This image, taken with Hubble's Advanced Camera for Surveys, reveals colors and differing intensities of individual stars as well dark filaments of dust and gas interstellar dust intersperced among the stars. NGC 253 is the dominant galaxy in the Sculptor Group of galaxies and resides about 13 million light - years from Earth. This galaxy is part of a detailed survey called the ACS Nearby Galaxy Survey Treasury program (ANGST). The natural - color images were constructed using Hubble observations taken in infrared, visible, and blue light. Data from the Cerro Tololo Inter - American Observatory in Chile were used to fill in small gaps in the Hubble image of NGC 253 / Bridgeman Images

PIX4564265: Blue stragglers in cluster 47 Toucan - Blue stragglers in globular cluster 47 Tucanae - This image obtained by the Hubble space telescope shows a detail of the 47 Toucan cluster near its center (the field is indicated on the left image taken from the ground). The yellow circles on the right image indicate the position of stars identified by the telescope as blue trainers. Because of the high density of stars within a globular cluster, a collision between two stars sometimes occurs, merging into a single young, bright and warm star called a blue straggler. The core of globular cluster 47 Tucanae is home to many blue stragglers, rejuvenated stars that glow with the blue light of young stars. A ground - based telescope image (on the left) shows the entire crowded core of 47 Tucanae, located 15,000 light - years away in the constellation Tucana. Peering into the heart of the globular cluster's bright core, the Hubble Space Telescope's Wide Field and Planetary Camera 2 separated the dense clump of stars into many individual stars (image on right). Some of these stars shine with the light of old stars; others with the blue light of blue stragglers. The yellow circles in the Hubble telescope image highlight several of the club's blue stragglers. Astronomers theorize that blue stragglers are formed either by the slow merger of stars in a double - star system or by the collision of two unrelated stars. For the blue straggler in 47 Tucanae, astronomers favor the slow merger scenario. This photo is a three - color composite of Wide Field and Planetary Camera 2 archival images taken with ultraviolet, blue, and violet filters. Green, blue, and red colors were assigned to the filters and scaled so that the red giant stars appear orange, the main sequence stars are white/green, and the blue stragglers are appropriately blue. The ultraviolet images were taken on / Bridgeman Images

PIX4564283: 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 oldest stars known today. Image obtained from the 3.9m telescope of Siding Spring, Australia. Among the many spectacular objects in the southern skies are two magnificent naked - eye globular clusters, omega Centauri and 47 Tucanae. These ancient cities of stars are captives of the Milky Way but were formed long before our Galaxy assumed its present shape, indeed these clusters have some of the oldest known stars. 47 Tuc is about 15,000 light years distant and contains several million stars, as many as some minor galaxies. The crowded central region leads to occasional stellar encounters and it is in 47 Tuc that rapidly - spinning pulsars have been discovered by radio astronomers. Although the light of globular clusters is dominated by so - called 'red' giant stars, their colour is no redder than a domestic tungsten lamp, so the true colour of 47 Tuc is close to the pale yellow / Bridgeman Images

PIX4564335: Globular cluster NGC 1806 in Dorado - Globular cluster NGC 1806 in Dorado - Image of the globular cluster NGC 1806 located in the southern constellation of Dorado. NGC 1806 belongs to the galaxy of the Great Magellan Cloud, a galaxy adjacent to our lactee path. Image obtained by the Hubble Space Telescope (HST). The NASA/ESA Hubble Space Telescope has turned its sharp eye towards a tight collection of stars, first seen 174 years ago. The result is a sparkling image of NGC 1806, tens of thousands of stars gravitationally bound into a rich cluster. Commonly called globular clusters, most of these objects are very old, having formed in the distant past when the Universe was only a fraction of its current age. NGC 1806 lies within the Large Magellanic Cloud, a satellite galaxy of our own Milky Way. It can be observed within the constellation of Dorado (the dolphin - fish), an area of the sky best seen from the Earth's southern hemisphere. NGC 1806 was discovered in 1836 by the British astronomer John Herschel. The Wide Field Channel of Hubble's Advanced Camera for Surveys was used to obtain this picture that was created from images taken through blue (F435W, coloured blue), yellow (F555W, coloured green) and near - infrared (F814W, coloured red) filters. The exposure times were 770 s, 720 s and 688 s, respectively, and the field of view is 3.1 by 1.9 arcminutes / Bridgeman Images

PIX4564370: Centauri Omega globular cluster - The globular cluster Omega Centauri, NGC 5139 - Visible to the naked eye in the southern hemisphere, Centaurus Omega is the most massive globular cluster in the galaxy. About 17,000 light years ago, millions of stars nearly 12 billion years old are concentrated here. NGC 5139 is the largest and most spectacular globular cluster in the entire night sky, and the largest in our galaxy. At 36 arc minutes, Omega Centauri is larger than the full moon in apparent size. It is located about 17,000 light years away from our Sun and at 4th magnitude, is easily visible without a telescope as a “” star”” in the constellation of Centaurus. It contains about 2 million stars, almost twice as many as M13. The stars in globular clusters are generally older, redder and less massive than our Sun / Bridgeman Images
