Globular cluster M70 in Sagittarius - Globular cluster M70 in Sagittarius - Star cluster located about 29,000 years away from Earth. Image obtained by the Hubble Space Telescope (HST). The NASA/ESA Hubble Space Telescope has captured the brilliance of the compact centre of Messier 70, a globular cluster. Messier 70 orbits close to the Milky Way's center, around 30 000 light - years away from the Solar System. Messier 70 is only about 68 light - years in diameter and can be seen, albeit very faintly, with binoculars in dark skies in the constellation of Sagittarius (The Archer). This picture was obtained with the Wide Field Camera of Hubble's Advanced Camera for Surveys. The field of view is around 3.3 by 3.3 arcminutes

Globular cluster G1 (Mayall II) - Globular cluster G1 (Mayall II) - The G1 globular cluster is the brightest globular cluster in the group of about thirty galaxies known as the Local Group (including the Lactee Way). It is orbiting the Andromede galaxy and contains at least 300,000 stars. This image is a composite of visible and near infrared images obtained by the Hubble Space Telescope in July 1994. Hubble Space Telescope has captured a view of a globular cluster called G1, a large, bright ball of light in the center of the photograph consisting of at least 300,000 old stars. G1, also known as Mayall II, orbits the Andromeda galaxy (M31), the nearest major spiral galaxy to our Milky Way. Located 130,000 light - years from Andromeda's nucleus, G1 is the brightest globular cluster in the Local Group of galaxies. The Local Group consists of about 20 nearby galaxies, including the Milky Way. A glimpse into the cluster's finer details allow astronomers to see its fainter helium - burning

Djorgovski globular cluster 1 in Scorpio - Globular cluster Djorgovski 1 in Scorpius - The Djorgovski globular cluster 1 is a cluster of light stars located near the galactic center, 40,000 years - light from Earth. Its discovery is recent (1987) and studies show that its stars are composed only of hydrogene and helium. The absence of heavier elements that are usually present in stars remains an enigma. Image obtained by the Hubble Space Telescope (HST). The NASA/ESA Hubble Space Telescope has imaged an area so jam - packed with stars that they almost overwhelm the inky blackness of space. This includes the globular star cluster Djorgovski 1, which was only discovered in 1987 Djorgovski 1 is located close to the centre of our Milky Way Galaxy, within the bulge. If the galaxy is thought of as being like a city, then this bulge is the very busiest district at its centre. Djorgovski 1's proximity to this hub - - within just a few degrees - - explains why the picture is teeming with stars.

This includes the globular star cluster Djorgovski 1, which was only discovered in 1987 Djorgovski 1 is located close to the centre of our Milky Way Galaxy, within the bulge. If the galaxy is thought of as being like a city, then this bulge is the very busiest district at its centre. Djorgovski 1's proximity to this hub - - within just a few degrees - - explains why the picture is teeming with stars.

Globular cluster M72 in Aquarius - Globular cluster M72 in Aquarius - M72 (NGC 6981) is a cluster of stars located about 50,000 years from Earth. Image obtained by the Hubble Space Telescope. This rich collection of scattered stars, known as Messier 72, is actually a globular cluster, an ancient spherical collection of old stars packed much closer together at its centre. As well as huge numbers of stars in the cluster itself the picture also captures the images of many much more distant galaxies seen between and around the cluster stars. English astronomer Pierre Megchain discovered this rich cluster in August of 1780, but we take Messier 72's most common name from Mechain's colleague Charles Messier, who recorded it as the 72nd entry in his famous catalog of comet - like objects just two months later. This globular cluster lies in the constellation of Aquarius (the Water Bearer) about 50 000 light - years from Earth. This image was taken with the Wide Field Channel of the Advanced Cam

Deep within the Milky Way lies the ancient globular cluster Terzan 5. This NASA/ESA Hubble Space Telescope image shows the cluster in wonderful detail, but it is the chaotic motions of its stars that make it particularly interesting to astronomers. Terzan 5 has an exceptionally dense core. As a result, it is thought to have one of the highest stellar collision rates for a globular cluster. And packed in at such close quarters, many stars are pushed so close together that they form tight binary systems.

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 c

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 clust

Around Baade's window - Around Baade's window - Stars field to the center of our galaxy. The bright star at the bottom of the image is Gamma of Sagittarius. The globular cluster in the center of the image is NGC 6522. Image obtained from the 1.2m Schmidt UK telescope of Siding Spring. The German - American astronomer Walter Baade selected for study a region of the crowded star fields in Sagittarius where he believed the Galactic dust obscuration was both uniform and minimal. He used this line of sight to establish the distance of the unseen Galactic centre, using variable stars as his yardstick. He found it to be about 30,000 light years away. This part of the sky, around the globular cluster NGC 6522, is now known as Baade's window. The brightest star in the photograph is gamma Sagittarii, a deep yellow, naked eye star of about third magnitude. It is in the foreground at a distance of about 100 light years
