PIX4564838: Globular cluster M14 in Ophiuchus - Globular cluster M14 in the constellation Ophiuchus - The globular cluster M14 is located in the constellation Ophiuchus at a distance of about 29,000 years - light; it extends over 72 years - light. M14 is a somewhat looser globular cluster than many, with a very small ellipticity (deviation from being exactly circular on the sky). Appearing in the constellation Ophiuchus, it is about 29000 light - years away and about 72 light - years across / Bridgeman Images
PIX4564913: Globular cluster NGC 6642 - Stars in globular cluster NGC 6642 in Sagittarius - Stars in globular cluster NGC 6642 in Sagittarius - Image of the center of the globular cluster NGC 6642 located in the constellation Sagittarius. The Hubble Space Telescope (HST) observed blue straggler. The core of NGC 6642, shown here in this Hubble Space Telescope image, is particularly dense, making this globular a difficult observational target for most telescopes. Using Hubble's ACS, astronomers have already made many interesting finds about NGC 6642. For example, many blue stragglers”” (stars which seemingly lag behind in their rate of aging) have been spotted in this globular, and it is known to be lacking in low - mass stars. This picture was created from visible and infrared images taken with the Wide Field Channel of the Advanced Camera for Surveys. The field of view is approximately 1.6 by 1.6 arcminutes. / Bridgeman Images

PIX4565155: Globular cluster M30 in Capricornus - Globular cluster M30 in Capricornus - The globular cluster M30 (NGC 7099) is located about 28,000 light years away from Earth. Globular clusters are generally peoples of very old stars, but here the Hubble space telescope has identified some young stars, blue stragglers. Messier 30 formed 13 billion years ago and was discovered in 1764 by Charles Messier. Located about 28 000 light - years away from Earth, this globular cluster - - a dense swarm of several hundred thousand stars - - is about 90 light - years across. Although globular clusters such as this one are mainly populated by old stars, the crowded field of stars leads to some old stars apparently reclaiming their youth in the form of blue stragglers. Researchers using data from Hubble's now - retired Wide Field Planetary Camera 2 (WFPC2) have identified two types of blue stragglers in Messier 30: those that form in near head - on collisions with one another and those that are in twin (or binary) systems where the less massive star siphons “” life - giving”” hydrogen from its more massive companion. This image of Messier 30 (M30) was taken by Hubble's Advanced Camera for Surveys (ACS) / Bridgeman Images

PIX4564826: Globular cluster NGC 6401 in Ophiuchus - Globular cluster NGC 6401 in Ophiuchus - The NASA/ESA Hubble Space Telescope has used its powerful optics to separate the globular cluster NGC 6401 into its constituent stars. What was once only visible as a ghostly mist in the eyepieces of astronomical instruments has been transformed into a stunning stellar landscape. NGC 6401 can be found within the constellation of Ophiuchus (The Serpent Bearer). The globular cluster itself is relatively faint, so a telescope and some observational experience are required to see it. Globular clusters are very rich, and generally spherical, collections of stars, hence the name. They orbit the cores of galaxies, with the force of gravity also keeping the stars bound as a group. There are around 160 globular clusters associated with our Milky Way, of which NGC 6401 is one. These objects are very old, containing some of the most ancient stars known. However, there are many mysteries surrounding them, with the origin of globular clusters and their role within galaxy evolution not being completely understood. The famous astronomer William Herschel discovered this cluster in 1784 with his 47 cm telescope, but mistakenly believed it to be a bright nebula. Later his son, John Herschel, was to make the same error - - evidently the technology of the day was insufficient to allow the individual stars to be resolved visually. NGC 6401 has confused more modern astronomers as well. In 1977 it was thought that a low - mass star in the cluster had been discovered venting its outer layers (known as a planetary nebula). However, a further study in 1990 concluded that the object is in fact a symbiotic star: a binary composed of a red giant and a small hot star such as a white dwarf, with surrounding nebulosity. It could be that the study in 1977 was simply a few thousand years ahead of its time, as symbiotic stars are thought to become a type of planetary nebula.

PIX4565011: Globular cluster M54 in Sagittarius - Globular cluster M54 in Sagittarius - The globular cluster M54 photographed by the Hubble space telescope (HST). M54 resides about 90,000 light years from Earth, in the dwarf galaxy of Sagittarius. The object shown in this beautiful Hubble image, dubbed Messier 54, could be just another globular cluster, but this dense and faint group of stars was in fact the first globular cluster found that is outside our galaxy. Discovered by the famous astronomer Charles Messier in 1778, Messier 54 belongs to a satellite of the Milky Way called the Sagittarius Dwarf Elliptical Galaxy. Messier had no idea of the significance of his discovery at the time, and it wasn't until over two centuries later, in 1994, that astronomers found Messier 54 to be part of the miniature galaxy and not our own. Current estimates indicate that the Sagittarius dwarf, and hence the cluster, is situated almost 90 000 light - years away - - more than three times as far from the centre of our galaxy than the Solar System. Ironically, even though this globular cluster is now understood to lie outside the Milky Way, it will actually become part of it in the future. The strong gravitational pull of our galaxy is slowly engulfing the Sagittarius dwarf, which will eventually merge with the Milky Way creating one much larger galaxy. This picture is a composite created by combining images taken with the Wide Field Channel of Hubble's Advanced Camera for Surveys. Light that passed through a yellow - orange (F606W) was colored blue and light passing through a near - infrared filter (F814W) was colored red. The total exposure times were 3460 s and 3560 s, respectively and the field of view is approximately 3.4 by 3.4 arcminutes / Bridgeman Images
PIX4565462: Galaxies Group: Stephan's Quintet in Pegase - Stephan's Quintet group of galaxies - Image obtained with the Hubble space telescope. This group of 5 galaxies is located about 270 million light years away from Earth. In this image three star-forming regions are visible: in the long arm of NGC 7319 (near the center); the gas debris of two galaxies, NGC 7318B and NGC 7318A (upper right); and in the upper left. Blue indicates that these stars are young. This NASA/ESA Hubble Space Telescope image is a close - up view of the central part of Stephan's Quintet, giving a magnificent view of a gigantic cosmic collision. Stephan's Quintet, as its name implies, is a group of five galaxies (NGC7317, 7318A, 7318B, 7319 and 7320) and lies about 270 million light - years away in the constellation of Pegasus (North - west of the Great Square of Pegasus). A sixth galaxy (NGC 7320C) lies south - east of the other five (upper left - hand corner of the overview image). The galaxy group was the first of its kind to be discovered and was found by the French astronomer Edouard Stephan in 1877, using the Foucault 80 - cm reflector at the Marseille Observatory. Today we know of hundreds of similar groupings, but few are as spectacular as Stephan's Quintet. This image is a mosaic of two pointings with the WFPC2 instrument made in December 1998 and June 1999 / Bridgeman Images
PIX4565503: Group of Galaxies: Stephan Quintet in Pegase - This group of 5 galaxies is located about 260 million light years away from Earth. These galaxies are interacting, however the NGC 7320 galaxy (down in the middle) would be 8 times closer to us. This group of galaxies is located about 260 million light - years away in Pegasus constellation. They are gravitationally interacting with the exception of the interloper NGC 7320 (bottom center) which is a foreground galaxy. Image made with a 32 inches telescope / Bridgeman Images
