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

PIX4565630: Galaxy clusters 1ES 0657 - 55 in the Carene - Gravitational lens in galaxy cluster 1ES 0657 - 55 - False color image of the distant galaxy cluster 1ES 0657 - 55 in the southern constellation of Carene obtained by the VLT. A gravitational mirage is visible in the form of a green arc at the top right of the image; it is the image of an even farther away galaxy curved and amplified by the gravity of this cluster. An Arc at z = 3.23 in galaxy cluster 1ES 0657 - 55. The galaxy cluster 1ES 0657 - 55 is located in the southern constellation Carina (The Keel), south of the Milky Way band. Its redshift has been measured as z = 0.29. It is a source of strong and very hot X - ray emission and has an asymmetric galaxy distribution, indicating a large mass and recent formation / 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

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
