Highlights from the VST image of Omega Centauri
This montage shows nine small cutouts from the VST image of Omega Centauri. Although each of them only shows about 0.3% of the full image they are still richly detailed and display the exquisite image quality of the telescope and camera. The upper left panel shows the core of Omega Centauri,...
Comparison of the field of view of VST/OmegaCAM and other telescopes
This image compares the field of view of OmegaCAM on the VST and several other telescope/camera combinations. The VST field is about four times the area of that of the Wide Field Imager and covers an area of sky more than 300 times greater than the imager on Hubble with the widest field, the...
VST image of the giant globular cluster Omega Centauri*
This VST image may be the best portrait of the globular star cluster Omega Centauri ever made. Omega Centauri, in the constellation of Centaurus (The Centaur), is the largest globular cluster in the sky, but the very wide field of view of VST and its powerful camera OmegaCAM can encompass even...
Omega Centauri with the NTT
Four views of Omega Centauri, the largest and most luminous globular cluster in the Milky Way Galaxy. The images, obtained in 1994, come courtesy of ESO's 3.6-metre New Technology Telescope (NTT) at the La Silla Observatory in Chile. The images demonstrate the improvement in spatial resolution...

TRAPPIST first light image of Omega Centauri
The globular cluster Omega Centauri was one of the targets observed for first light of the TRAPPIST national telescope at La Silla. The cluster contains as many as ten million stars. This image, 20 arcminutes across, shows only the central parts of Omega Centauri. It is made by combining data...
The globular cluster Omega Centauri*
The globular cluster Omega Centauri — with as many as ten million stars — is seen in all its splendour in this image captured with the WFI camera from ESO's La Silla Observatory. The image shows only the central part of the cluster — about the size of the full moon on the sky (half a degree)....
Comparing AO techniques
Central parts of the globular cluster Omega Centauri, as seen using different adaptive optics techniques. The upper image is a reproduction of ESO Press Photo eso0719, with the guide stars used for the MCAO correction identified with a cross. A box shows a 14 arcsec area that is then observed...
The globular cluster Omega Centauri (MAD/VLT)
Mosaic of images covering the central parts of Omega Centauri, the most luminous globular cluster as seen from Earth. The images were taken with CAMCAO in Br-gamma for a total exposure time of 5 minutes (the original pixel scale is 0.028 arcsec). The stars in the 2 arcmin field of view have a...
Omega Centauri tracking test
Omega Centauri is the most luminous globular cluster in our Galaxy. As the name indicates, it is located in the southern constellation Centaurus and is therefore observable only from the south. The image shown here was obtained with the VLT on May 16, 1998, in red light (R band), i.e. while the...
Omega Centauri
This photo of Omega Centauri, the brightest and largest globular cluster in the sky, was obtained with the Danish 1.5 m telescope at the ESO La Silla observatory. It shows the central part only; the cluster is actually much larger than the field reproduced here. At a distance of about 16,500...
The importance of high resolution
These four images illustrate the importance of improving the resolution of astronomical images. They also demonstrate the great potential of the ESO New Technology Telescope (NTT), in terms of finer detail and fainter limiting magnitude. The field shown is near the centre of the bright southern...
Small field near centre of Omega Centauri (NTT)
Small field near centre of Omega Centauri (NTT). This false-colour photo has been reproduced directly from the best CCD frame obtained with the ESO New Techonology Telescope during the night of ``first light'' on March 23, 1989. It shows a field near the centre of the bright southern globular...
Small field near centre of Omega Centauri (3.6m)
This photo has been reproduced from one of the best photographic plates of the globular cluster Omega Centauri obtained with the ESO 3.6 m telescope. It shows a field near the centre; the size is approximately square arcsecond. The exposure lasted 6 min 15 sec and was made on blue-sensitive...
The Omega Centauri globular cluster of stars
The Omega Centauri globular cluster of stars is the brightest of its type in the sky and contains several millions of stars. It is here reproduced from a photographic plate obtained with the ESO 1 m Schmidt telescope. The exposure time was 15 minutes on a blue-sensitive emulsion. The field...
Globular cluster Centauri observed with the ESO NTT
Globular cluster Centauri observed with the ESO NTT. This is one of the first astronomical images obtained with the ESO New Technology Telescope, during the night of "first light'' (March 22 - 23, 1989). The CCD image was immediately transfered via a satellite link to the ESO Headquarters in...
NASA's Chandra Catches Spider Pulsars Destroying Nearby Stars
A group of dead stars known as "spider pulsars" are obliterating companion stars within their reach.
Globular cluster 47 Tucanae
This NASA/ESA Hubble Space Telescope image shows a globular cluster known as NGC 104 — or, more commonly, 47 Tucanae, since it is part of the constellation of Tucana (The Toucan) in the southern sky. After Omega Centauri it is the brightest globular cluster in the night sky, hosting tens of...
Globular Cluster Omega Centauri Captured by NEWFIRM on the Blanco Telescope
During its commissioning and capabilities testing, astronomers used NEWFIRM on the Víctor M. Blanco 4-meter Telescope at Cerro Tololo Inter-American Observatory (CTIO) in Chile to capture a spectacular image of the Omega Centauri globular cluster. At about 17,000 light-years from Earth in the...

NGC 5139: Omega Centauri Widefield
The name "Omega Centauri" should hint that this particular cluster is quite special. As viewed from Earth, Omega Cen (as it is often called) is certainly one of the most dazzling of globular clusters that orbits our galaxy. Before the use of good telescopes (and optics) this cluster was known...
