PIX4568468: Open cluster M11 in the Sobieski ECU - M11 open cluster in Scutum - M11, NGC6705, is a particularly compact and star-rich open cluster (about 2900), located in the constellation Sobieski ECU. The image is of a young cluster of stars located in the direction of the constellation named Scutum. This tight gathering of stars, known as the Wild Duck Cluster or M11, features about 2,900 individual members - most of them are approximately 250 million years old - the newest stars appear white - blue, the older ones have a yellowed appearance. This group of stars hangs in space about 5,000 light - years from Earth / Bridgeman Images
PIX4566971: Chateau - Abbadia Observatory - Abbadia Castle - Property of the Academy of Sciences, located in Hendaye, in the Atlantic Pyrenees, this castle was the home of Antoine d'Abbadie (1810 - 1897), a scholar and explorer. It was built between 1864 and 1879 by the architect Eugene Viollet-le-Duc (1814 - 1879), instead of an astronomical observatory dating back to 1858. The castle houses a new observatory, equipped with a Meridian bezel of 2.05 m focal length, with which d'Abbadie participated in the elaboration of the map of the sky “”. Passionate about astronomy, Antoine d'Abbadie made many trips, notably to observe total eclipses of the Sun in Norway (1851), Spain (1860) and Algeria (1867). In 1882 he observed Venus's passage before the Sun from the West Indies. He was president of the Academy of Sciences in 1891 and 1892. Abbadia Castle, owned by the French Academy of Sciences, was built by Eugene Viollet le Duc between 1864 and 1879. It houses a former astronomy observatory. / Bridgeman Images
PIX4569009: Open cluster Trumpler 5 in Unicorn - Open cluster Trumpler 5 in Monoceros - Trumpler 5 is a cluster of stars aged 125 million years. Image obtained by Siding Spring's 3.9m telescope As they age, open clusters of stars begin to lose their identity. This is partly because the brighter members tend to self - destruct as supernovae, and, though the group members share a common motion through space, they are only loosely bound. Thus stars drift away from the cluster in a process that accelerates with time. However, some clusters are big enough to retain their identity much longer than usual, and Trumpler 5 is one such. Its age is estimated to be 125 million years, and it must have been a spectacular sight in its youth. It seems to be at the edge of the Monoceros molecular cloud, where star formation is continuing new generations of young clusters / Bridgeman Images
PIX4568137: Open cluster M44 in cancer - Open star cluster M44 in Cancer - M44 is a cluster of stars located only 600 years - light from Earth, in the constellation Cancer. M44 (NGC 2632), the Beehive Cluster, also known as Praesepe, is an easy naked eye object more than twice the size across of the full moon, and has thus been noted since prehistoric times. It was one of the first objects on which Galileo trained his newly acquired telescope. M44 is one of the nearest open clusters, close to 600 light - years away / 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
PIX4568519: Open cluster NGC 6830 in the Little Fox - Open cluster NGC 6830 in Vulpecula - The NGC 6830 cluster is a cluster composed of 20 to 30 very scattered stars; its distance is estimated at 5,500 years - light. This cluster of 20 to 30 stars is located 5 500 light years away / Bridgeman Images
PIX4565601: Clusters of distant galaxies CL0024+1654 - Distant cluster of galaxies CL0024+1654 - False color image of cluster CL0024+1654 obtained with the 12k camera of CFHT (Canada France Hawaii Telescope) in Hawaii. This cluster is 4.5 billion light years away. This is a colour image of the galaxy cluster CL0024+1654 obtained with the CFHT12k camera at the Canada France Hawaii Telescope on Mauna Kea (Hawaii). Distance of 4.5 thousand million light - years (about one third of the look - back time to the Big Bang) from Earth. The cluster clearly appears as a concentration of yellow galaxies in the centre of this image although cluster galaxies actually extend at least to the edge of this image. This image measures 21 x 21 arc - minutes / Bridgeman Images

The open cluster M34 (NGC 1039) is located 1400 light - years away in the direction of the constellation Perseus; it contains about a hundred stars in a region some dozen light - years across, and is visible to the naked eye under good conditions.

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. M46 (NGC 2437) is at a distance of about 5,400 light - years away from Earth with an estimated age of about 300 million years. It contains about 500 stars of which 150 are bright. Planetary nebula NGC 2438 (top) doesn't seem to belong to the cluster / Bridgeman Images

PIX4567707: Double cluster of Persee - Double cluster in Perseus - NGC884, on the left and h Persei NGC869 on the right are located about 7000 years - light in the constellation Persee. The double cluster in the constellation Perseus, normally known by its Greek designation transliterated. chi Persei (NGC884, on the left) and h Persei (NGC869) are about 7000 light - years away and less than 100 light - years apart. Although open clusters are quite common, this pair is exceptional due to the large number of young bright O and B stars in each, and their closeness / Bridgeman Images
