Hyades and Pleiades open clusters - Hyades and Pleiades open clusters - The Hyades cluster, bottom left, with the bright star Aldebaran. In the center, the Pleiades cluster. These two clusters belong to the constellation of the Taurus of which Aldebaran is the brightest star; it is a red giante. The Pleiades is a relatively nearby open cluster, which is located at a distance of 440 light years. The Hyades (at bottom left) is another open cluster located even closer at a distance of 153 light years

Interacting galaxies NGC 3256 - Interacting galaxies NGC 3256 - The special galaxy NGC 3256 is located about 100 million light years away from Earth in the southern constellation of Sails. A vestige of the collision of two galaxies, this system presents a double nucleus and many young clusters of stars. Image obtained by the Hubble Space Telescope on November 5, 2001. NGC 3256 is an impressive example of a peculiar galaxy that is actually the relict of a collision of two separate galaxies that took place in a distant past. The telltale signs of the collision are two extended luminous tails swirling out from the galaxy. NGC 3256 belongs to the Hydra - Centaurus supercluster complex and provides a nearby template for studying the properties of young star clusters in tidal tails. The system hides a double nucleus and a tangle of dust lanes in the central region. The tails are studded with a particularly high density of star clusters. Image taken by the Hubble space telescope on November 5

Star cluster M46 and M47 and NGC 2438 in the stern - Open clusters M46 and M47 - M46 (NGC 2437), on the left, is a cluster of age stars 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. On the right, cluster M47 (NGC 2422). Between the two clusters we can see a third one: NGC 2425. M46 and M47 are two open clusters that lie a little more than 1 degree apart in the sky in the constellation of Pupis. M46, containing planetary nebula NGC 2438, is seen at left in this photo, and M47 is at right. M47 is a bright cluster that can be seen with the unaided eye under dark skies. It is comprised of about 30 stars, and is 30 arc minutes in diameter and has an overall brightness of 4.4 magnitude

IC1848 nebula and the star cluster embedded in it are located just 4 degrees north of h Persei, one of the two members of the famous Double Cluster. The same nebula also hosts Collinder 33 (Cr33) and Collinder 34 (Cr34) star clusters. The faint nebulae IC1871 and Sh2 - 198 are just near the IC1848. Just one and a half degree north - west from IC1848 is located the IC1805 complex. This rich but faint nebular complex resides 5* NNE of the Double Cluster in Perseus. The largest and very diffuse part of it, IC1805, contains large and bright star cluster Melotte 15 at its center. Other star clusters (NGC1027, Berkeley 65 and Markarian 6) are located around its edges. The brightest part of IC1805 complex consists of nebulae IC1795 and NGC896 which together are intersected by narrow NW to SE streaks of dust.

Image obtained by Siding Spring Clusters of bright blue stars like M11 are found scattered among the spiral arms of the Milky Way and other galaxies like it. They are a clear sign that star formation is active, because such clusters are usually very young and short lived. The stars in M11 all formed from the same material and at about the same time, a few million years ago. In 100 million years or so, all the brightest stars in the group will have evolved into cool supergiants and exploded as supernovae, leaving behind large numbers of low mass, relatively faint stars whose lives will be much longer and whose end will be much less dramatic. Located in the constellation of Scutum, it is sometimes mistaken for a loose globular cluster. M11 is also called the “” Wild Duck Cluster”” because of it's resemblance to a flight of wild ducks when viewed in a telescope. M11, wit

M87 elliptical galaxy in Virgo - M87 elliptical galaxy in Virgo - The M87 galaxy (NGC 4486) is 54 million years ago - light from Earth, in the heart of the Virgin's cluster. This composite image obtained by the Hubble space telescope in 2003 and 2006 shows a gigantic jet of gas material ejected from the heart of the galaxy. A supermassive black hole would have caused this jet. The monstrous elliptical galaxy M87 is the home of several trillion stars, a supermassive black hole, and a family of 13,000 globular star clusters. M87 is the dominant galaxy at the center of the neighboring Virgo cluster of galaxies, which contains some 2,000 galaxies. Amid the smooth, yellow population of older stars, the two features that stand out most in this Hubble Space Telescope image of M87 are its soft blue jet and the myriad of starlike globular clusters scattered throughout the image.

Centaur Omega globular cluster - NGC 5139 Omega Centauri globular cluster - Located 17,000 years ago - light from Earth in the southern constellation of Centaur, Omega Centaur contains several million stars and is one of the oldest objects in our galaxy. One of the richest in the Milky Way, Omega Cen contains several million stars, but unlike its southern rival, 47 Tucanae, it has a relatively open structure. Like most galactic globular clusters, the stellar population of Omega Cen identifies it as one of the oldest objects associated with the Milky Way, indeed its age is comparable to that of the Universe itself. The cluster contains a large number of RR Lyrae variable stars which enable its distance to be determined as 17,000 light years

Galaxy clusters LCDCS - 0829 - Galaxy cluster LCDCS - 0829 - Gravitational lenses in the galaxy cluster LCDCS - 0829. Image obtained by the Hubble Space Telescope. The NASA/ESA Hubble Space Telescope usually works as a solo artist to capture awe - inspiring images of the distant Universe. For this picture, though, Hubble had a helping hand from the subject of the image, a galaxy cluster called LCDCS - 0829, as the huge mass of the galaxies in the cluster acted like a giant magnifying glass. This strange effect is called gravitational lensing. The object was discovered during the Las Campanas Distant Clusters Survey, which explains the cluster's unusual name. This survey was carried out in March 1995 using a 1 - metre telescope at the Las Campanas Observatory in Chile. More than one thousand clusters of galaxies, most of them previously unknown, were found in a dedicated survey of a long, but narrow, section of the southern sky.

Spiral Galaxy NGC 4522 - Galaxy Spiral NGC 4522 - Moving at a speed of 10 million km/h in the Virgin's galaxy cluster, this spiral galaxy loses some of its gas. NGC 4522 is located about 60 million light years away from Earth. Image obtained by the Hubble Space Telescope. NGC 4522 is a spectacular example of a spiral galaxy that is currently being stripped of its gas content. The galaxy is part of the Virgo galaxy cluster and its rapid motion within the cluster results in strong winds across the galaxy as the gas within is left behind. Scientists estimate that the galaxy is moving at more than 10 million kilometers per hour. A number of newly formed star clusters that developed in the stripped gas can be seen in the Hubble image. The stripped spiral galaxy is located some 60 million light - years away from Earth

Constellation Toucan - Constellation of Tucana - Constellation of Toucan near the galaxy of the Little Magellan Cloud. Tucana, represents the Toucan (Rhamphastos toco, a large - billed tropical bird), and was named by Johann Bayer in 1603. It was also known to some astronomers as Anser Americanus, the American Goose, as late as the 1870s. The constellation is circumpolar (never sets) for most of the southern hemisphere, and lies south of Phoenix, bordering on Octans which includes the south celestial pole. There are no named stars in Tucana, but it contains one of the finest globular clusters in the sky, 47 Tucanae. This is named for a star but is easily seen to be diffuse with the unaided eye. By chance 47 Tuc is seen alongside the much more distant Small Magellanic Cloud (SMC), a satellite of the Milky Way
